- -={ DataCOM Systems -- Three Nodes }=-
-
- It's now official, the new DataCOM PCBoard(tm) node went online
- on August 31, 1986. This new system is for IBM-PC or clone users
- only as all online software is IBM-related. The system accepts
- 1200 or 2400 baud at logon and displays online color and graphics
- to other IBM or compat machines with CGA card and color monitors.
- If you have only a monochrome system, then answer "N"o at the
- first prompt for color graphics.
-
- This new system becomes DataCOM's third remote node and adds
- another 32mb to our online data storage. With the multi-user
- system and the new IBM system added together we now offer our
- callers over a 100 megabytes of online files!! TBKUG/DataCOM
- members have access to all three systems for one low annual fee
- of $35.00.
-
- According to Telenet, PC Pursuit service will be available for
- the Tampa/St Petersburg/Clearwater areacode (813) by early fall
- and is one of their next projects. Telenet is also installing
- 2400 baud modems in all the present 14 outdial areacodes and will
- be doing the same to any new areas being added. The new 2400
- baud service will be provided at no extra cost and will be
- available in most areas very soon.
-
- We are offering a 20-minute demo access on the new PCBoard to
- non-members who complete an online registration. You will have
- enough time to see what the board looks like and you can download
- the DATACOM.INF, MEMBER.APP, and MASTER.ARC files. The
- MASTER.ARC file is a daily-updated listing of all online files on
- the PCBoard system, it presently lists about 18mb of files!

- -={ Kaypro II/IV 256k RAM Mod Update }=-
-
- by Dr. Michael W D Liddle
-
-
- Ron Rock had problems with my 83 Kaypro II/IV 256K upgrade. I
- hope the following will help him and others. I also hope that
- those of you who didn't spot my two typing mistakes will be
- generous and forgive me.
-
- Ron found that after installing the mod while still using 64K
- chips that small programs worked but large ones didn't. This
- suggested to me that different parts of RAM were being addressed
- simultaneously. I had this at one stage whilst debugging my
- prototype although from a different cause.
-
- NOW FOR THE CAUSE AND CURE :- My circuit as published has PIO 1
- and A14b coming from U3 labelled the wrong way around. I accept
- full responsibility for this mistake it slipped past all my
- checks. Pins 10 and 11 of U3 (the 74LS153) should connect to
- A14B (Kaypro U33 pin 11) and Pin 12 of U3 goes to the PIO as PIO
- 1 (PAD E29).
-
- My error results in A14 not reaching the memory and thus the
- first 16K overlaps the second 16K whilst the third 16K overlaps
- the fourth 16K. Thus any program bigger than 16K overwrites
- itself and dies. This would explain Ron Rocks problem.
-
- If you get this far you will find another problem. The REFRESH
- for RA8 won't work until you earth PIN 2 of the 74LS393 (U1).
-
- Anybody adding 256K to their machine please let me know how you
- get on with it (especially Mr Rock and his son to who I owe
- special thanks for bringing this problem to my attention). Do
- tell me of any other problems and any solutions you find to them.
-
-
- P.S. The transposition of A14 and A15 (U33 pins 10 and 11) was
- something else I hadn't noticed. I took the lid of my machine
- and find that Micro-C have it right. I apologise to anyone who
- had problems using the circuit in the file that appeared on
- various BB's shortly before Micro-C published the official
- version. This particular bug would only show up once you had
- 256K up and running.
-
- P.P.S. The Micro-C version is correct in earthing pin 2 of the
- 74LS158 although my system does work fine without this it may
- make a difference to others.
-
- P.P.P.S. Since submitting the design to Micro-C I have altered
- the PIO connections. Both work with the 63K CBIOS I recently
- made available however the ZCPR3 BIOS needs the newer PIO
- arrangement. For those who want an exact duplicate of my system
- the following is straight from my (working) motherboard to you:
- PIO 1 = PAD 29. PIO 2 = PAD 31. PIO 3 = PAD 28.

- -={ ZCPR3 Shells - What Are They? }=-

-
- Msg #3858 posted 08/17/86 by JOHN LIN
- To: ALL USERS About: What are Shells? (6 lines)
-
- It did not occur to me last night as I was reading the latest
- issue of Z-NEWS as to what shells really were. The Conn manual
- gives a treatment to shells, but assumes you have seen them in
- use already. Does anyone with greater background in operating
- systems have a defintion of shells and what they can be used for
- practically?
-
- Msg #3859 posted 08/17/86 by Steve Cohen
- To: JOHN LIN About: What are Shells? (56 lines)
-
- [Reply to msg #3858]
-
- Good question, John, and one that is not so easy to answer.
- A shell in Zcpr3 anyway is a program which when loaded into
- memory, "installs" itself in such a way that it "pre-empts" the
- user interface of the operating system (The CCP) and substitutes
- its own interface. Whenever the Multi-Command Buffer is empty,
- you would normally be put back into the CCP. Instead, with a
- shell you are put into its special and hopefully more convenient
- (for certain purposes anyway) interface. Thus if you want to do
- a lot of file management, coying, deletion, etc., VFILER is a
- much more convenient place to be than the ZCPR3 prompt. In fact,
- VFILER has been so expanded with so many options it is for me
- almost always a more convenient place to be such that VFILER is
- practically my operating system.
-
- VCED is another shell (HSH is quite similar in function). It
- is virtually identical to the straight CCP except that it
- "remembers" in an accessible file commands previously entered,
- yet another kind of function that can be done with a shell. MENU
- and VMENU allow the user to enter a number of possibly complex
- multiple commands at a single key-stroke by a substitution
- mechanism (VFILER also has this capability). Yet another shell
- is my own W.COM which allows wildcard capability to be given to
- some commands that do not normally accept them. It, unlike most
- other shells, does this without further user input once the
- initial command is typed. It creates a new command line
- incorporating the name of an unambiguous file name in place of
- the wildcard typed in by the user, doing so sequentially through
- a list ofall matching files.
-
- Soon you will probably see a text editor that is a shell. An
- ideal use for this would be with assemblers or compilers. The
- compiler command line would be generated from the editor and
- control would be returned to the editor after the compilation
- something like the way Turbo-Pascal works now. The advantage of
- the shell set-up is much greater flexibility. One of my gripes
- with Turbo is you can't go TURBO MYPROG.PAS and immediately start
- editing that file. You will also have access to the full Z-
- SYSTEM commands including aliases, ARUNZ, CMDRUN and all that
- other neat stuff you don't get from TURBO.COM's internal mini-
- CCP. (Yes that's what it is.)
-
- So you see there is no limit to the variety of uses for
- shells. What they hold in common is:
-
- 1> the ability to generate new command lines (either manually or
- automatically or by some sort of simplifying substitution scheme)
- and pass them to the CCP for execution.
-
- 2> the fact that control is returned to the shell after the
- command has been executed rather than to the raw CCP and,
-
- 3> which I haven't mentioned but must quite obviously be the
- case, that every shell has a way of exiting such that control is
- then passes back to the command processor.
-
- There is one major disadvantage of shells. They must be
- loaded into memory from disk each time they are re-invoked. Thus
- hardware speed is critical for shell performance, so much so that
- VCED and HSH are virtually useless on floppy-based systems and
- only really come into their own on Ramdisk-based systems. To
- some extent this is also the case with VFILER, VMENU and MENU.
- But with fast hardware, shells greatly increase performance with
- only a small penalty in speed.
-
- Thanks for asking the question. You stimulated me to expound
- on something I understand but have never tried explaining to
- anyone else.

- [CP/M]
-
- RCPM0986.LQT The Sept-Oct 1986 remote CP/M systems listing.
- This list is updated every month - please use the latest copy to
- avoid placing modem calls to numbers no longer in service.
-
- LX12.LBR This version of LX (Execute file from a library)
- determines if the COM file to be executed is a ZCPR3 utility. If
- it is, it auto-installs it (sets the address of the environemment
- descriptor) so you don't need to install with Z3INS.
-
- PHONER.CMD This is a DbaseII phone-dialing routine, tested under
- Dbase 2.41 on a Kaypro II (old II w/ upgrade). It's a handy
- demonstration of the Dbase Poke routine, commented so users can
- adabpt the program to their needs.
-
- SPLTFST2.LBR is a trick little program that "splits" large files
- into smaller files by number of lines. I like it, I can split a
- large file into small enough chunks to use KP-EDIT or VDO.
-
- FINDF25.LBR Latest version of FINDFast, a ZCPR3-only file
- finding utility. Let's you choose a single drive to search...
- ex: ff b:*.mqg to search drive B: for any MQG ext files.
-
- DD12.LBR is a ZCPR3-specific directory program with all sorts of
- commandline options and toggles.
-
- NEWRITKP is a new formatter for TOUR20 (PD outline processor)
- files. Real Turabian outlines with nice indentation. Runs on
- KP, source (Pascal) included. Buggy, but produces nice output.
-
- VIDLOG20.LBR is set of dBASE command files to provide an easy
- method of maintaining a simple catalog of your video tapes. The
- only requirements for this program is that you own dBASE II, and
- that you can type. Two members had been damaged in the
- originally named VIDEOLOG.LBR and are replaced in this library.
-
- [IBM-DOS]
-
- PKX32A11.COM is a self-unpacking archive that contains Phil
- Katz's newest ARChive utilities: PKARC11 is a very fast utility
- to create, add, or freshen an existing archive. PKXARC32 is a
- very fast archive extractor utility. The doc files are also
- included in this self-unpacking archive.
-
- ARCA122 is the latest (fast) archive create, add, or freshen
- utility from Vern Buerg and Wayne Chin.
-
- ARCE206 is also from Buerg/Chin and is a super fast archive
- extractor utility.
-
- NOTE: All of these new ARC utilities are MUCH faster than the
- ARC512.EXE utility from S.E.A. and are completely compatible in
- format. The users are benefitting from a minor update "war"
- currently going on between Phil Katz and Buerg/Chin to see who
- will create the fastest ARC utilities.
-
- PCBBS28D.LQT The Sept 1986 remote PC (IBM) systems listing.
-
- LIST60H.ARC is the latest version of Vern Buerg's excellent ASCII
- file listing utility. This program just keeping better with each
- new release. You can list files one at a time or use wildcards,
- send the output to screen or printer or both. LIST now has a
- split-screen mode where you can freeze part of one file on the
- top window and list another on the bottom window. LIST will even
- display binary files! I would recommend this utility very highly
- to anyone with a DOS machine!
-
- CT515 is an excellent personal/small business finance manager,
- you can keep track of up to TEN checking accounts, likewise for
- investment/savings accounts.
- SHOW is a Dir utility that displays the filenames, sizes, and
- also the cluster(s) used by the files.
-
- DPROT102.ARC allows you to set your hard disk drive to read only
- status while testing newly downloaded (and unknown) programs.
-
- CHAIN, OWNER, & MARKC are three nice utilities for finding out
- what file uses what cluster(s) on the actual disk. MARKC is used
- to mark or unmark "bad" disk clusters.
-
- JAXHST3A.ARC is a remote mini-host for IBM-PCs or compatibles.
- It allows access to the DOS commandline and uses the XFER150
- program for XMODEM/YMODEM protocol transfers. This is a nice
- system for those who wish to access their computer remotely
- without the hassle of setting up a "full blown" remote system.
-
- QMODEM22.ARC Latest version (as of 9/1/86) of QMODEM. This is a
- super modem program for any IBM-PC or compatible with internal or
- external Hayes-type smartmodem. Supports all popular file xfer
- protocols and has moveable pop-up help and xfer display windows.
-
- EZFRMC24.ARC is EZ-FORMS ver c.24. This is a form generator that
- makes any form that you may need. It comes with several forms
- that you can use or adapt for your needs. Documentation is
- thorough and included.
-
- ALTPAGE.ARC Print on both sides of paper. Do one side and then
- flip it over, calculates internally for multiple page printouts.
-
- GALXY12C.ARC is a Wordstar clone with multiple-file editing,
- multi-windows, word-wrap, print formatting, pop-up help menus.
- All of GALAXY's functions are faster than Wordstar and it's
- screen appearance is very pleasant and easy to work with. Five
- stars for this editor!
-
- DISKVR41.ARC Diskover v 4.1. Prints an insert for disk jacket
- which lists all files and explodes ARC and LBR files. It uses
- the compressed printing mode of most dot-matrix printers, has
- built-in config for Epson FX/RX/MX, IBM graphic, IBM Pro, HP
- Laser Jet, Okidata 192/193/Plug-n-Play, Toshiba P321, AT&T
- 473/478/479, & C ITOH 8510/1550 printers - plus you can enter
- your own sequences for any printer not listed. This new version
- now has a preview function for viewing the output before printing
- if desired. I'd be lost without this fine utility!
-
-
- -={ Until Next Month ... }=-
-
- That does it for another month folks, check out the DataCOM Super
- Systems, we just added a new 85mb drive. Lots of new files
