Opening Remarks John Lohmeyer, the Chairman, called the meeting to order at 9:00 a.m., Monday June 20, 1988. He thanked Jochen Polster and John McCool of AMD for hosting the meeting. He also thanked Classic Conferences for arranging the meeting. As is customary, the attendees introduced themselves. A copy of the X3T9.2 membership list was circulated for attendance and corrections. Copies of the draft agenda and application forms for membership and mailings were made available to all attendees. Information on X3T9.2 was made available to the new attendees. 2. Approval of Agenda The draft agenda was approved with the following additions: 5.1 AMP letter (X3T9.2/88-68) 9.6 LOG SELECT and LOG SENSE commands (X3T9.2/88-6 Rev 1) 10.3 Proposal to add Stewart/Viking connector as Alt. #1 (X3T9.2/88-67) 10.4 Physical Architecture IBM Proposal (X3T9.2/88-69) The connector issues were relegated to 10:30 AM Tuesday. 3. Attendance and Membership Membership requirements were reviewed. The Chairman stated that since the last meeting Tom Anderson had replaced Dan Amey as ELCO's principal member. New members at the meeting were: Paul Nitza of OTL Engineering Ed Cieniawa of Panduit Corp. Tetsuro Motoyama and David Koger of Ricoh Corp. Tom Gardner of Technology Forums, Ltd. Peter Kurbikoff and Karl Kwait of Viking Connectors Enclosure (1) is the list of attendees at the meeting. Enclosure (2) is the X3T9.2 membership changes since the last minutes and enclosure (3) is the current X3T9.2 membership list. 3.1 Roll Call of Members in Jeopardy The Chairman stated that he had sent jeopardy letters to all representatives of the following organizations: Amphenol Corp., Archive Corp., Datacopy Corp., Northern Telecom, Inc., Prime Computer, Inc., and Storage Technology Corp. The letters said that these organizations failed to attend two of the last three plenary meetings and that their membership would be terminated unless they attended the June plenary meeting. Representatives were present from all of the organizations in jeopardy except Prime Computer, Inc. Dal Allan moved and John Lohmeyer seconded that Prime Computer's membership be retained as if they had attended this meeting since Mike Fitzpatrick is seriously ill. The motion carried unanimously. John Lohmeyer agreed to send a letter to George Till and Allen Ross of Prime notifying them of the situation regarding membership. 4. Approval of Minutes - Apr. Meeting St. Petersburg Beach (X3T9.2/88-040) The draft minutes were approved with the following corrections: "Dan Davie's" should be "Dan Davies'" in several places. The second sentence of paragraph three of Section 8.1 should be deleted. ENDL is not shown as attending. In fact, Dal Allan was there. As usual, the corrected minutes will be placed on the SCSI Bulletin Board, but will not be re-distributed in the mailing. 5. Document Distribution The Chairman stated that he had sent the most recent mailing to the X3 Secretariat on May 17 via Federal Express. It was not forwarded to the copy service until June 6, nearly two weeks later. As a result, most people did not receive their mailings on time. CBEMA has recently hired Kate McMillian to replace Patti Steiner. Hopefully, with the better staffing level, future mailings will not be delayed. The Chairman also stated that he had sent 222 letters to Principals, Alternates, and Observers on his mailing list who were not on the CBEMA mailing list for the first mailing. Included with the letter were subscription forms for the CBEMA mailings. The following new documents were distributed at the meeting: Document Doc Date Author Description of Document ------------- -------- --------------- --------------------------------------- X3T9.2/88-6 3/16/88 J. McGrath LOG SELECT/SENSE commands Rev 1 X3T9.2/88-48 6/16/88 J. Morse SCSI-2 Pinouts for Low and High Density Rev 1 Cables X3T9.2/88-59 5/26/88 J. Lohmeyer SDTR wording revisited (again and Rev 1 again) (and again) X3T9.2/88-63 6/16/88 J. Stai SCSI Additional Sense Codes for Processor Devices X3T9.2/88-65 6/20/88 P. Boulay Asynchronous Event Notification Revision X3T9.2/88-67 6/13/88 D. Hatch Proposal to add Stewart/Viking connector to SCSI-2 as Alternative #1 X3T9.2/88-68 6/17/88 C. Brill Alleged Patent Infringement Document Doc Date Author Description of Document ------------- -------- --------------- --------------------------------------- X3T9.2/88-69 6/20/88 G. Marazas Physical Architecture -- SCSI-2 Interface X3T9.2/88-70 6/17/88 Anderson/ Additional Sense Qualifier Codes DeYoung Enclosure (4) is the current 1988 document register. 5.1 AMP letter (X3T9.2/88-68) Chuck Brill presented a letter which stated that AMP had filed a law suit against Stewart Stamping request a declaratory judgment that AMP's connectors do not infringe Stewart Stamping's patents and that the patents are invalid due to prior art. Furthermore, AMP stated that they will indemnify any customers who purchase the SCSI-2 connector from them. David Hatch of Stewart Stamping stated that AMP had not responded to their request for connector drawings and samples for Stewart Stamping's lawyers to evaluate. Stewart Stamping also wants a quick settlement of the issue. 6. Liaison Reports 6.1 ISO Gene Milligan, the X3T9 International Representative, reported. He had sent a letter withdrawing the Rigid Disk Interface from consideration as an ISO standard. The appropriate person at ANSI had failed to send the SMD standard to ISO for "fast track" processing. The latest delay is due to ANSI's inability to obtain copies of the document (which they publish). The Flexible Disk Interface standard has been submitted to ISO. A letter requesting volunteers for the US delegation to the Tokyo ISO SC- 13 meeting had been sent to several X3T9 members. Arrangements have been made for delegation at the ShibaPark hotel. JTC-1 has a project underway to provide an on-line database to monitor the various ISO standards and projects. It is supposed to be implemented by end of 1988. 7. Review of Old Action Items 7.1 Dan Davies will propose revised wording in the retry counts and algorithms of REQUEST SENSE and MODE SELECT. Carry over. 7.2 Larry Lamers will review the changes made in the WRITE SAME CDB. He was previously assigned to move bit 0 to bit 2 in the WRITE SAME CDB and to reserve bit 0. In Rev 4, Bit 0 is RelAdr and Bit 2 is reserved. Completed by Jeff Stai. 7.3 Dal Allan will prepare ESDI rev 2.A and mail an original to John Lohmeyer. Complete. 7.4 John Lohmeyer will request X3T9 to substitute ESDI Rev 2.A for Rev 2.0 for the public review. Complete. 7.5 John Lohmeyer will seek X3T9 resolution on the registration authority issue. X3 and ISO are actively working on this issue. They had a meeting May 25 and 26 at CBEMA to discuss the general issue of registration authorities. Del Shoemaker attended the meeting. (See agenda item 9.4.) 7.6 Jim Semenak will find a home for the ECA control bit. Complete. Resolved at the working group. 7.7 Paul Boulay will reword the AEN and unit attention paragraph. Complete. Paul has submitted a proposal. 7.8 Steve Goldman will draft an implementors note clarifying the differences between synchronous and wide negotiation procedures. Carried over due to the arrival of a healthy baby. 7.9 Ed Gardner will revise the pin assignments for wide SCSI to reflect the changes made at the St. Petersburg Beach meeting. Complete -- document X3T9.2/88-048 Rev 1 contains the changes. It was not available in time for the June mailing. 7.10 Paul Boulay will revise the CD-ROM section of SCSI-2. Carried over. 7.11 Steve Goldman will provide a description of the sense key, additional sense code, and additional sense code qualifier hierarchy. Carried over due to the arrival of a healthy baby. 7.12 Bill Spence will further clarify the SDTR wording. Complete. John Lohmeyer foolishly offered some additional changes and has now prepared X3T9.2/88-059 rev 0 and rev 1, further clarifying the SDTR wording. 7.13 Ed Gardner will revise 88-048 (pin assignments) and send an electronic copy to John Lohmeyer. This is actually a duplicate action item to 7.9. The electronic copy arrived a few hours too late for the mailing. 7.14 Dan Davies will draft an implementors note warning that length information may not be available when using the SILI bit. Complete. 8. Working Group and/or Project Status Reports 8.1 ESDI John Lohmeyer reported that ESDI began its first public review period on June 3, 1988 and it will close on October 3, 1988. The document is known as BSR X3.170-198X. Copies can be purchased from Global Engineering Documents (800-854-7179 or 714-261-1455) for $30.00. The document is at Revision 2.A. The WordStar version of this document is available on the SCSI Bulletin Board. 8.2 Flexible Disk No report was given. 8.3 SCSI General Working Group (X3T9.2/88-050) John Lohmeyer reported that a working group meeting had been held May 9- 11, 1988 in Minneapolis. Gerry Houlder of CDC hosted the meeting. The working group made a number of recommendations that should be reviewed by the full committee. 8.3.1 Additional Sense Codes (X3T9.2/88-032 Rev 1) The working group spent most of its time preparing X3T9.2/88-032 Rev 1. This document contains a recommended set of Additional Sense Codes which maintains maximum compatibility with CCS and resolves most of the incompatibilities that existed in SCSI-2 Rev 3. The working group recommends that the remaining anomalies be retained to maintain compatibility with existing products. It was noted that an error exists in ASC,ASCQ 30h,00h: "INQUIRY" should be "IDENTIFY". Bill Spence moved and Gene Milligan seconded that the committee accept X3T9.2/88-032 Rev 1 and incorporate it into SCSI-2 Rev. 5. The motion carried unanimously. 8.3.2 Embedded Cache Disk Parameters (X3T9.2/88-049 Rev 2) There was some discussion over whether the "Write Retention Priority" field in the Read Caching Parameters page should be moved to the Write Caching Parameters page. After some off-line discussion, Jim McGrath agreed that the Write Caching Parameters page (currently one bit) should be merged with the Read Caching Parameters page to make one Caching Parameters page. Dal Allan moved and Peter Johansson seconded that X3T9.2/88-049 Rev 2 as modified be accepted for incorporation into SCSI-2 Rev 5. The motion carried: 28 in favor, 2 opposed. Jim Semenak will edit this proposal into one page. 8.3.3 Unimplemented Page Codes, Revisited The May working group felt that defining two mechanisms for reporting that a MODE page is not implemented is one too many. They recommend that we "undo" the March working group's addition of allowing unsupported pages to be returned with a zero page length. Since this issue is believed to be somewhat controversial, the working group asked that it be added to the plenary meeting agenda. Dexter Anderson moved and Paul Nitza seconded that the target respond to unimplemented pages with CHECK CONDITION status and the sense key set to ILLEGAL REQUEST. The motion carried: 32 in favor, 1 opposed. 8.3.4 "User-friendly" MODE SELECT commands There was an extensive discussion at the working group meeting about MODE SELECT command implementations that automatically deduce a consistent set of MODE parameters based off of one (or more) parameters such as sector size. It had been suggested that a "2-bit" proposal be developed to define whether permissive or strict parameter interpretation is to be used. This would actually define three interpretations: strict, permissive, and target's choice. Rather than solving the general case, the working group recommended that we address this issue on a case-by-case basis. Wording has already been adding to solve the current issue -- if an initiator only specifies the block size, then the target may set the other pertinent MODE parameters according to its own algorithm. There was general agreement with the working group's recommendation. 8.3.5 SDTR Wording Clarification (X3T9.2/88-059 Rev 1) Bill Spence managed to pass this "hot potato" to John Lohmeyer. John prepared 88-59 which was included in the June mailing. Almost immediately after Rev 0 went out, Bill suggested a further problem with the wording. John did not have the good sense to pass the hot potato back to Bill, but instead prepared Rev 1. Copies of rev 1 were distributed at the meeting. This revision restores the requirement that an SCSI device must respond to an SDTR message whenever it is received. There was general agreement to include the revised wording in SCSI-2 Rev 5. 8.3.6 Active Differential Termination on Cable B (X3T9.2/88-060) John Lohmeyer had suggested that the termination on the differential Cable B be made active instead of passive. This would be required if we expect to adopted the SCSI-3 proposal from AT&T to permit more than 8 devices on Wide SCSI. There is no similar problem with the single- ended Cable B, since no passive termination is defined for single- ended drivers. Bill Spence moved and Jim Schuessler seconded that X3T9.2/88-60 be incorporated into SCSI-2 Rev 5. The motion carried: 20 in favor, 1 opposed. 8.4 Fiber Optic Physical Layer Study Group A fiber optic study group meeting was held June 2-3, 1988 in the Sunnyvale Holiday Inn. The meeting was hosted by AMD and chaired by Dal Allan. Minutes of this meeting will be included in the next X3T9.2 and X3T9.3 mailings. The principal purpose of the meeting was to define the functional requirements for a fiber optic physical layer for IPI (most likely IPI- 3), HSC, and SCSI. The meeting also explored the fiber optic technologies that are expected to be available in the 1990 timeframe. The next meeting is scheduled for August 11 & 12 somewhere in the San Jose area. The challenge for SCSI to utilize this physical layer is to packetize the command set and move the functionality of the message system up into the logical level. 8.5 Other Items The proposed definition of caching contained in X3T9.2/88-30 Rev 1 was accepted for incorporation in SCSI-2 Rev 5. X3T9.2/88-42 on the power-on initialization procedure for sequential- access devices (Appendix H) was accepted for incorporation in SCSI-2 Rev 5. X3T9.2/88-43 Rev 1 on active format field was accepted for incorporation in SCSI-2 Rev 5. The Exabyte request (X3T9.2/88-52) for a helical-scan density code was accepted. The working group recommended that the term "non-changeable" be replaced with "target defined". Editors were requested to make the change. 9. Old Business 9.1 BUSY issue (short vs. long?) (X3T9.2/87-192 Rev 3 - Semenak) Jim Semenak had presented a third version of his proposal to the May working group. Several people, especially Bob Snively, took strong exception to his proposal for a number of reasons. The objections had not surfaced in the discussion of previous revisions, but they probably should have. It was speculated that the objections had not surfaced because people had not understood the previous revisions. Since the working group could not reach consensus, this item was retained on the plenary agenda for resolution. Jim requested that his proposal be withdrawn. 9.2 Review of SCSI-2 Draft Document (X3T9.2/86-109 Rev 4) The figure and table references are out of sync. John Lohmeyer promised to attempt to synchronize these references in SCSI-2 Rev 5. 9.3 Pin assignments for new SCSI connectors John Lohmeyer stated that the electronic copy of X3T9.2/88-048 Rev 1 had arrived on the SCSI Bulletin Board a few hours after he sent the mailing to the X3 Secretariat. Consequently it was not included in the mailing. The Rev 1 document included the pin assignments agreed to at St. Petersburg plus a DEC proposal to move toward allowing more terminator power lines. John included 88-048 Rev 1 in SCSI-2 Rev 4b, an interim draft prior to SCSI-2 Rev 5. The terminator power proposal is clearly identified as not being discussed or accepted yet. A key issue concerning pin assignments is whether 28-AWG 25-mil centerline flat cable really can be used to mass-terminate non-shielded connectors in a daisy-chain fashion. If we must return to 50-mil cable, then a different set of pin assignments should be made. The following information was provided by Fielding S. Tabb of Hitachi Cable Manchester, Inc. for 28-AWG 25-mil center flat cable: Characteristic Impedance: Ground to Signal: 86 ohms 22.8 picofarads @ 1Khz Ground to Signal to Ground: 56 ohms 42.4 picofarads @ 1Khz UL listing 2962 for less than 30 volts (4-mil insulation) There is no connector currently available that will permit mass- termination of 25-mil 28-AWG cable in a daisy-chain fashion. The connector manufacturers expect that it will be available. Twisted-flat cable for use with differential signals is available, but it is costly. 9.4 Registration Authority (X3T9.2/88-061) John Lohmeyer sent a letter to Del Shoemaker explaining the SCSI-2 registration issues. The letter was intended to aid Del in preparing for an ISO Registration Authority meeting which was held in Washington at CBEMA on May 25-26, 1988. A second meeting of Registration Authority Group (RAG) was planned for Tuesday through Thursday, June 28-30, at CBEMA in Washington, DC. The SCSI-2 standard should define its registration procedures before the document is forwarded. 9.5 Schedule for SCSI-2 John Lohmeyer said that he had added this item to the agenda in hopes that we could agree on a realistic schedule for forwarding SCSI-2. We had obviously missed the schedule established in June '87 for forwarding in February '88. The current editing schedule called for preparing revision 5 in early August. John said that NCR would make copies of revision 5 to bring to the August plenary meeting and that revision 5 would be in the September '88 mailing. He said that he hopes we can forward in October or December. A straw poll was taken on how change information should be presented in rev 5. The choices were: 1. Clean document (no change information shown) 2. Additions only (deletions not shown) 3. Deletions & Additions (Current format) The straw vote was 21/25/13. Therefore, SCSI-2 Rev 5 will only indicate additions via underscore. 9.6 LOG SELECT and LOG SENSE commands (X3T9.2/88-6 Rev 1) Jim McGrath described the changes that were incorporated in rev 1 of his proposal. The implementors note on counter lengths was not added but should have been. The page code value will be moved to byte zero of the page structure. The implied non-volatile requirement will be removed. There are currently four pages defined from Bill Spence and one page defined from Greg Floryance. Jeff Stai moved and Barton Phillips seconded that the LOG SELECT/SENSE commands be deferred to SCSI-3. The motion failed: 6 in favor, 18 opposed, and 3 abstained. 10. New Business 10.1 Review of new documents X3T9.2/88-048 Rev 1 - SCSI-2 Pinouts for low and high density connectors. This document described the pin assignments agreed to at the St. Petersburg meeting plus it introduces a proposal from Digital Equipment Corp. to redefine some pins as open (<10K Ohms to some other pin in the cable) so that in the future the number of pins for TERMPWR could be increased. DEC is interested in using higher-current single-ended drivers to use terminators with a better match to the characteristic impedance of the cable. Such terminators would draw more current, increasing the TERMPWR current requirements. Also, using a smaller wire gage would require more TERMPWR lines. John Morse accepted an action item to provide more a substantial justification for accepting this proposal. X3T9.2/88-063 Rev 0 - Additional Sense Codes for Processor Devices. Jeff Stai's proposal was remanded to the Boise working group. X3T9.2/88-065 Rev 0 - Asynchronous Event Notification Revision. Paul Boulay's proposal was remanded to the Boise working group. X3T9.2/88-67 Proposal to add Stewart/Viking connector as an alternate non-shielded connector. Consideration was deferred until Tuesday morning (see agenda item 10.3). X3T9.2/88-68 Amp letter. (See agenda item 5.1, above.) X3T9.2/88-69 SCSI-2 Physical Architecture Consideration was deferred until Tuesday morning (see agenda item 10.4). X3T9.2/88-70 Additional Sense Code Qualifiers. Dexter Anderson's proposal was remanded to the Boise working group. 10.2 Agenda for Boise Working Group The following agenda was drafted for the Boise working group. Consideration of item 41 is scheduled for Monday afternoon. Agenda Items for SCSI-2 1. [] bracket removal 2. Review of S2R4 3. WORM Device Specific MODE SELECT Page [88-44] (P. Boulay) 4.

Expanded RelAdr Bit [88-007] (Boulay) 10.3 Proposal to add Stewart/Viking connector as Alt. #1 (X3T9.2/88-67) John Lohmeyer stated that he had received a letter from David Hatch proposing that the Stewart/Viking connector be added to SCSI-2 for internal interconnections. The letter requested that the connector be designated "Alternative #1", but designations "Alternative 1" and "Alternative 2" are already in use. Therefore, if this proposal were accepted by the committee, it should properly be designated "Alternative 3". In his letter, David had requested that the issue be put to a committee vote. Therefore John took the liberty of drafting the a formal motion as follows: "Mr. Hatch moved and Mr. Snively seconded that the Stewart Stamping and Viking Connector proposed connector design be added to SCSI-2 as the third non-shielded connector alternative." David Hatch made a brief presentation in defense of the motion. Then an extensive discussion ensued. Gene Milligan moved and Bill Spence seconded that the motion be amended so that the Stewart/Viking connector be considered for SCSI-3 unless the Marazas/IBM proposal is considered for SCSI-2, in which case this issue should be revisited. The motion to amend failed: 4 in favor and 34 opposed. Gene Milligan moved and Paul Nitza seconded calling the question. This motion failed: 5 in favor and 33 opposed. There followed a lengthy discussion on the needs for a lower profile unshielded connector to use on 3.5-inch products. It was pointed out that while current product offerings may be too high for some 3.5-inch disk drives, the draft standard does not require connectors to be too high. Concern was voiced over the viability of using 25-mil cable to daisy- chain connections. The current pin assignments have been optimized on the assumption that 25-mil cable will be viable. If this assumption is wrong, then the pin assignments may have to change. The Stewart/Viking connector provides a "back-end" that is optimized for 50-mil ribbon cable. Chuck Brill moved and Bill Spence seconded that we call the question. The motion failed: 13 in favor and 13 opposed. Dal Allan moved and Jeff Stai seconded that consideration of the motion on the floor be deferred until the next plenary meeting. The motion failed: 7 in favor and 24 opposed. AMP, et al., accepted an action item to provide drawings of a low-profile version of their connector for the committee's consideration at the next plenary. A roll call vote was taken on the main motion with the following results: Name Organization Vote ------------------------------ ------------------------------ ---- Mr. Robert C.

The Chairman expressed frustration with the assumed SD-2 rule that members of a Technical Committee or Task Group must vote on technical issues. Many of the "absent" votes were the result of committee members leaving the room rather than being forced to vote on an issue that they either did not understand or did not care about. Preventing abstentions merely disrupts meetings with members rushing for the door. Mr. Brill moved and Ron Schlitzkus seconded a motion to establish a standing rule to prevent unannounced attempts to change or add to the SCSI-2 connectors. The effect of this motion is to require a two thirds majority to change or add a SCSI-2 connector, unless the proposal is described in a mailing prior to the meeting. The motion carried: 30 in favor and 5 opposed. During the debate on the above main motion questions on the "two-weeks rule" and the quorum came up. The two-weeks rule is an X3 rule contained within the SD-2 that requires documents be sent to committee members at least two weeks prior to the meeting before the committee can take a "final action" on the document, unless no one objects. The SD-2 fails to define what a final action is, but it has usually been interpreted with X3T9 to be forwarding a document. The SD-2 rules state that a quorum is 1/3 of all voting members. A meeting can continue with fewer members present until a member questions the quorum. 10.4 Physical Architecture (X3T9.2/88-69) Jerry Marazas gave a presentation on the IBM proposal to add ten lines to the SCSI A cable. The architecture was designed to coexist with existing devices, both single-ended and differential. IBM requested that this proposal be added as an option to the SCSI-2 document. The additional lines provide an electronic means to overwrite the physical device address for performance tuning and for automatic address configuration improving "user friendliness". The detection of an external cable terminator is also a feature of the IBM proposal. The first decision was regarding whether this proposal should be considered under SCSI-2 or SCSI-3. Bill Spence moved and Bob Snively seconded that 88-69 be accepted for consideration in SCSI-2. (The item would be added to the queue for SCSI- 2.) Gene Milligan moved that the motion be amended to allow suspension of the five-minute rule on discussion and replace the Spence motion with a full discussion in the meeting. Dal Allan seconded. The amendment passed: 20 in favor and 12 opposed. After more discussion Bill Spence withdrew his original motion. (Chairman's note: I am not sure that all of this is strictly according to Robert's rules, but the end result was general agreement that we should discuss the IBM proposal further before making a determination of whether it belongs in SCSI-2 or SCSI-3). A Special Subject Working Group (SSWG) was established to examine the proposal further. It was scheduled to meet Monday afternoon at the next general working group in Boise. The decision on whether it will be a SCSI-2 or SCSI-3 item was deferred until the Colorado Springs meeting. 11. Review of Action Items 11.1 Dan Davies will propose revised wording in the retry counts and algorithms of REQUEST SENSE and MODE SELECT. 11.2 Steve Goldman will draft an implementors note clarifying the differences between synchronous and wide negotiation procedures. 11.3 Paul Boulay will revise the CD-ROM section of SCSI-2. 11.4 Steve Goldman will provide a description of the sense key, additional sense code, and additional sense code qualifier hierarchy. 11.5 John Morse will provide more a substantial justification for accepting his proposal to add more terminator power lines. 11.6 John Lohmeyer will send a letter to George Till and Allen Ross of Prime notifying them of the situation regarding membership. 11.7 Jim Semenak will edit X3T9.2/88-049 Rev 2 into SCSI-2 Rev 5. 11.8 Bill Spence will prepare the log pages for LOG SENSE/SELECT commands. 11.9 AMP, et al., will provide drawings of a low-profile version of their connector for the committee's consideration at the next plenary. 11.10 AMP will prepare a thesis on removal forces for the high-density connectors in the absence of a retention mechanism. This paper should compare and contrast the current 50-pin design and the chip "walking out" phenomena of dip sockets. 11.11 AMP will investigate the mass termination capability of 25-mil, 28-AWG ribbon cable. 11.12 Harvey Waltersdorf has an action item to provide the UL, CSA, VDE listings and the electrical characteristics of 25-mil centerline, 28- AWG ribbon cables. 12.
