- PROLOG-TO CBM:
-
- In July 1985 we purchased our first C=128 Computer, upgrading from
- three years of use of the C=64 for our routine business operations. We
- are a small AI/Expert Systems R&D Consulting firm dedicated to the
- propagation of the considerable talents of our Principals to a
- distinguished list of Clients, which includes Fortune 500 firms. Most
- of our services are conducted on Large MainFrames and MiniComputers -
- but we learned a considerable respect for the capabilities of the CBM
- MicroComputers through practical business use of the C=64. The
- economies were outstanding in both the Hardware and Software costs for
- this purpose.
-
- Our first C=128 (July 85) was a Beta Unit, distuinguished by a two
- column grey right border on the Graphics Screen, and improper vertical
- striping of all VIC output in odd color assortments. A replacement was
- not available until October - during which time, denied full use of the
- 64 and 128 Modes, we began evaluating the CP/M Mode. Ours was one of
- the first of many letters to CBM pointing out the numerous "bugs" and
- deficiencies in the first two issues of the CP/M+ Operating System.
- Long TeleCons with CBM Customer Relations about our early findings
- resulted in a formal invitation in December 1985 to Beta-Test the 6
- December '85 Revisions and CBM future upgrades to CP/M+.
-
- Two preliminary "Letter Reports" were submitted on a timely basis,
- allowing CBM sufficient time to respond to our recommendations before
- completing our Beta-Tests. This is our Final Report to CBM of the
- results of our tests and evaluations. It has not been paid for by CBM,
- nor will it be. It is therefor PROPRIETARY COPYRIGHTED information and
- the property of RAMA Corporation, intended for public release to the
- Media catering to Commodore Computer users. It was submitted to CBM
- March 1986 for comment and response.
-
- Two attempts to gain interest of RUN and Compute Gazette in publishing
- this report have resulted in null answers.

-
- INTRODUCTION:
-
- Like Christmas, there is always a sense of tense excitement when
- unwraping your new Computer, be it the first, third or n-th. It was
- July '85 and I had anticipated this moment since last February when the
- first public information releases had been made on the new Commodore
- C=128 MicroComputer. The decision had been made then to upgrade our
- Business Computer System with the new C=128. I had read everything
- available, even written a brief article about this "NEW THREE-IN-ONE"
- for a local Commodore User Group......
-
- FINALLY! It had arrived and I eagerly got it out of the boxes and
- quickly connected to the existing peripherials (a compatability unusual
- in itself). The old C=64 was laid aside....retired from its three
- years of daily fault free service as our busy business computer... I
- connected the 40/80 Column Screen switching box (made a month earlier),
- then the Modem, High-Res Composit Color Monitor, Printer, and two new
- 1571 "smart" Disk Drives. NOW... lets see what this beauty will do!
-
- I doff my hat to the sage who once said "anticipation is nine-tenths of
- the pleasure....", however in this case, he was wrong. The C=128 was
- MORE than Commodore had said it would be... so busy selling "features"
- CBM had dramatically understated the full CAPABILITIES of this Mean
- Machine! It was perfect for our business use - and a great deal MORE.
-
- The uneasiness caused by the opening screen - which states that BASIC
- 7.0 was Copyrighted in 1977 by MicroSoft, and updated by CBM in 1985 -
- soon disapeared as I began to try some of the BASIC features provided.
- Help, Tron, Sound, Graphics, Sprites and the new BASIC 7.0 commands
- made programming effortless - all greatly enhanced by the 40/80 Column
- Screens, extended CNTRL and ESC codes. I BOOTed the CP/M+ which I
- hadn't played with for years (V 1.4 ....as I recall) and discoverd a
- near CP/M-86 capability imbedded in the Calls - approaching a REAL
- "Operating System"... that CP/M never was before.
-
- I had purchased an early Beta-Test Unit, distuinguished by a small
- brown dot under the "M" in the word COMPUTER on the Name-Tag, and a
- grey stripe on the right side of the Graphics Screen. This one had a
- ROM fault that caused random character errors and a bad VIC Chip. Our
- software worked alright for business use...but the Graphics were
- Verticle Striped in an odd assortment of colors. This didn't bother me
- much... having accepted it as a high probability for one of the first
- units sold... but a replacement would not be available until October.
-
-
- DISCOVERING CP/M+:
-
- Denied the full use of graphics in the 64 and 128 Modes of operation
- until a replacement Unit was received, I concentraited on the fully
- independent CP/M Mode....learning all there was to know about the CBM
- upgrades to CP/M 3.0, and ordering the "DRI Special Offer". The later
- is one of the best buys in the country... and probably the ONLY
- "support" we will ever receive from Digital Research Incorporated (DRI)
- for their Operating System. The "Two Utility Disks" in this DRI Offer
- are more than just that... they contain the assembly level ASM/LIB
- Files, Macros and Object Codes - plus the necessary MAC, RMAC, SID, ED
- etc. utilities which are ESSENTIAL if any programming is to be done, or
- Public Domain Software installed on the System. The two inch thick,
- three-in-one Manual(s) that comes with these disks, also an essentail,
- is cryptic to a fault.... but I would hate to do without it. It, sort
- of, explains the functions (NOT the functional use of) the Utilities
- and reveils the content and details of the BIOS, BDOS, CCP and other
- incorporated subroutines of the Operating System. A forth manual,
- "Programmer's Utilities Guide for the CP/M Family of Operating Systems"
- refered to frequently in the above Manual(s), is not available from
- DRIs publisher for seperate purchase. Rather than pay an outlandish
- $75 for repeated purchase of the Manual(s) materials, I recommend the
- Osborne/McGraw-Hill CP/M Users Guide, Third Edition. CBMs Manual and
- Programmers Guide should have eliminated this serious problem, but did
- not.
-
- The first thing to do when starting any new System is read the File
- Headers and DOC files. The HELP file on the first Distribution Disks
- serves as a reference untill the "DRI Special Offer" arrives - although
- it is just as cryptic as the DRI Manual(s). There is NOTHING you can
- do with all these files until you obtain some Applications Software or
- the ESSENTIAL Utilities for Programing contained in the DRI Utilities
- Disks. You're stuck, except to study what you have on the origional
- Distribution Disks, and try them out against each other. Furthermore,
- the first two CP/M+ issues by CBM did not permit a required DEVICE
- assignment to a Modem (RS232 Port) - and thus NO Telecommunication and
- Downloading of Applicaions Programs is possible. Remember, the big
- sales pitch by CBM for the CP/M+ Operating System was the "Free
- Software" available in the Public Domain - now inaccessable.
-
-
- DISCOVERING PROBLEMS IN CP/M+:
-
- I tried the simple exercises of the CP/M+ Operating System and
- Utilities and fortunately all the Utilities DID work properly (I have a
- few words later to describe my feelings about the archaic SID and ED
- file editors). The first, most obvious problem discovered was that the
- Printer would not properly copy (echo) the screen - no matter what I
- did to the Intereface configuration switches. This was later reveiled
- to be a problem within the Interface (it works fine in 64 and 128
- Modes) that was not designed to handle the eight-bit ASCII or PETASCII
- codes (nulling the high-bit), and was "coloring" the printing with odd
- [SHRT] "soft-returns" mid-line and mid-word. I also had some random
- graphics and Font Switching codes being sent to the Printer at carrage-
- returns. Asking others about their Printer problems reveiled that ONLY
- the CARDCO Plus and Plus-G interfaces did not have all these CP/M+
- problems, although Upper-Case characters were still being printed in
- Italics. I had to get rid of the PETASCII and Print with the Interface
- in ASCII Transparent mode.
-
- Further testing reveiled that, although the intent of CBM was to
- default (Boot) the system in an ADM-31 Terminal Configuration, the BIOS
- KEYCODEs were wrong...resulting in a keyboard that, at best, was and
- ADM-3A Terminal Configuration plus some odd ESC codes unique to the
- C=128. The Console Commanad Processor (CCP) was also deficient and
- trying to install and run Commercial Applications Software was, in many
- cases, a disaster. In some, the opening Screen and Menus were in all
- graphics characters (the alternate key-set produced by ESC-G-1) or
- resulted in a resounding CRASH because they wrote to high memory
- overwriting the CCP. Furthermore, random character errors kept showing
- up on the screen and printer outputs, along with double characters -
- most annoying and unpredictable crashes resulted. At that time I was
- compelled to advised CBM of my consternation and frustrations. My
- letter was not complementry - I learned later that it had been read to
- the Board of Directors and circulated to CBM Management. The reply (I
- actually got one..) was from the CBM Legal Council denying all
- responsibility. (Naturally! Thats what he is paid for.)
-
- When the "DRI Special Offer" finally arrived six weeks late, the
- READ-ME file was not the least bit illuminating, but the MAKEROM.DOC
- and MAKESYS.DOC files did guide me through the exercises of assembling
- and linking the Object Codes that fill these disks. DO NOT try to make
- sense of the File names and Headers with the DRI Manual(s) - there is
- NO CORRELATION between these, (this information should have been in the
- READ-ME file, according to the DRI Manual). This lack of correlation
- was the source of enormous frustration to me and my innate compulsion
- to MAKE IT WORK! The second curiousity was that although the MAKESYS
- exercise did, infact, assemble and install a new (and supposidly
- improved) CP/M+ System.... ALL the faults discovered in the first issue
- prevailed - including the denial of use of a Modem for Downloads. IN
- ADDITION the MAKEROM exercise dead-ended with a set of BIOS "CXROM...."
- files of absolutely no utility or reason, since they had already been
- included in the MAKESYS files under other/different Object Code file
- names. DRI refused to answer my questions - sending me back to CBMs
- Hotline Mummies. The Author, finally reached directly, admitted to me
- that this mess was intentional, not an accident or oversight, in the
- process of developing these Files. It DOES provide us with a fairly
- complete set of the CP/M+ Object Codes...and we may all be greatfull to
- him for these in any future upgrades of our CP/M+ Operating System.
-
-
- INVITED TO BETA-TEST CP/M+ REVISIONS:
-
- I tried using SID and ED to find and make corrections to the CX....ASM
- files that governed the functions that were faulty in the BIOS/BDOS/CCP
- Codes... and decided this was an exercise in futility without very
- extensive study. Did you ever try to edit someone elses Codes, on a
- limited display screen, without seeing the Curser position and without
- having full screen edit capability..... it is AWFUL!! Furthermore, some
- of the most dramatic Crashes imaginable resulted from these efforts -
- resoundingly slaping my sensativities as to my own capability as a
- programmer (now seriously in doubt). Once again I let CBM know about
- my concern and frustrations with this situation - and was invited to
- help constructively solve them as a "Beta-Tester" for the third issue
- of CP/M+ which was alledged to solve all these problems. It would
- accomodate the Modem , RAM Disk and other DEVICE assignments, and much,
- much, more. Having already developed a small effection for this "Mean
- Machine" - I agreed to Beta-Test the CP/M+ revisions.
-
- This latest CBM revision of CP/M+ (6 Dec. 85) for the C=128 was to be a
- fully corrected version, removing of all the faults I had cited above.
- It would now allow Modem (RS232 Port) operation in CP/M for downloading
- software that would make the Beta-Tests a significant exercise, and
- covering a wide range of Utilities and Applications Software. I
- immediately sent some 38 letters to the top CP/M Software suppliers
- (very few of whom responded) for Test Samples. I also promptly
- downloaded (in 128 Mode) and converted the Public Domain release of the
- 4 Dec. CP/M+ BIOS, and went to work in getting a first-class Terminal
- (MODEM7) Program up and operating. Finding a properly overlayed
- IMP244.LBR (which I highly recommend) was a bit of a struggle, but it
- had just made available on ComPuserv. My Downloading began, and over
- the next few weeks - while waiting for CBM to send me the Beta-Test
- Issue of the CP/M+ BIOS - I accumulated an outstanding set of Utilities
- and Software.
-
-
- THE FIRST CP/M+ REVISION:
-
- The disk that arrived from CBM in January was folded into a U and
- stuffed into our Postal Box. With heart sick feelings about the
- condition of the disk (and a bitter word or two to the Postmaster)... I
- hurried back to the office and was pleased to find I could gently
- unfold it and run the Disk in the 1571 Drive - copying everything
- promptly to a new disk, just in case.
-
- Along with a new CPM+.SYS file was a SCREEN40.COM file that I
- investigated immediately. This little ditty solved several serious
- problems. It turned off the 40 Column Screen and completely eliminated
- the random character errors experenced above, particularly in 1200 Baud
- Modem transfers. The source was thus reveiled for at least one of the
- faults in the CCP/BIOS - although SCREEN40 is no more than a Band-Aid
- for more serious problems that were still internal to the CP/M+
- Operating System. My downloads from the BBSs would now be clean of
- random errors that plagued our first test software. About this same
- time the C=128 "Configurator" CONF.COM and its Menued HLP file became
- available on the Public Domain. With the proper settings of the O.S.
- using CONF.COM, and the Printer interface set transparent to eight-bit
- ASCII, my STAR Delta 10 Printer properly recieves and prints the direct
- ASCII codes without interference from the interface. Calling CONF
- PRT1=ASCII turns off the PETASCII conversion (that has been fouled up
- in the CP/M+ Codes) needed for CBM Printers. Calling CONF 40COL=OFF
- turns off the 40 column screen (like SCREEN40), switches to Two
- MegaHertz and gets rid of the random character errors at 1200 Baud and
- double keying problems. There is a full menu of other configuration
- control and set-up Calls in CONF.COM, as well, (see below) that
- provides the needed configuration control of the system - including
- screen colors. The controls provided by CONF.COM are REQUIRED for the
- successful use of the 6 December issue of CP/M+. They are only a Band-
- Aid "fix" however, to the many serious problems that are still imbedded
- in the CP/M+ source codes.
-
- With the improvement of the printer operation (by setting the
- PRT1=ASCII in CONF.COM) I realized my first real success with echoing
- the screen, and running several NLQ Font Programs that bit-map output
- to the dot-matrix printer. I use the "CBM emulate mode" of the
- Interface only in 64 and 128 Modes now, with the software designed for
- CBM Printers. With the Beta-Test CP/M+ you must still configure
- Commercial Software for the ADM-3A Terminal Configuraton, and thus are
- denied use of the full keyboard features and the much faster Screens of
- ADM-31 Terminal operation. Since this is not a hardware problem, but a
- fault of the CP/M+ Codes, we should expect CBM to properly correct this
- problem. Several of the Commercial and Public Domain Software
- packages evaluated require that the CCP be overlayed or made a PRL
- (program relocatable) File to work with their Resident Commands. As
- the CCP MUST be reprogrammed to correct remaining errors in its codes,
- WE NEED an assembly level copy of the CCP (ie CCP.ASM or CPR.ASM) to
- successfully run this excellent new software. Several Z80
- Disassemblers I have tried all crash the CP/M+ O.S. - although nearly
- all CP/M 2.2 or 3.0 Commercial Software and Utilities run great on the
- C=128 (in ADM-3A Terminal mode with the Band-Aids affixed to the O.S.).
-
- Not one piece of Osborne Software from the First Osborne Groups (FOG)
- Public Domain Library that I have acquired will run on the C=128. Yet
- nearly all CP/M-80 Software from the SIG-M Library, and so called
- "vinilla" Programs (ie. without special Machine Unique calls imbedded)
- downloaded HAVE properly run. (I do NOT recommend that the C=128
- CP/M+ be reconfigured to accomodate Osborne Software - even the
- Osborne Executive's CP/M 3.0). All Osborne, QX-10 and KayPro Disk
- configurations DO load and copy properly (even between disk formats)
- with the 1571 Disk Drives. As a matter of fact....the 1571 is
- remarkably fast and fault free in the CP/M Mode (although we cannot
- say the same for the 128 Mode where the DOS fails periodically).
- Although our C=128 Unit does have the infamous "shifted Q problem",
- our C=64 software is 100% compatable. Even the fully loaded FLIGHT
- SIMULATOR II will run without having to disconnect the Printer
- Interface and Cassette ports (thanks to CBM for cleaning this mess
- up).
-
-
- SOFTWARE REPORTS = SUCCESSES:
-
- The following abstracts are briefs of the software I have tested and
- which does operate successfully on the C=128 (under the certain
- conditions stated above and with the band-aids) with the 6 Dec. Beta-
- Test issue of CP/M+. We anticipate that CBM will make all necessary
- changes to the BIOS and CCP, and correct the remaining faults
- discovered in the codes, for the final release of the Upgraded CP/M+
- Operating System scheduled for May of this year (now 5 Months late).
- I will not belabor this point further here. Only positive results are
- presented below, but rest assured - there were many failures.
-
-
- MODEM PROGRAMS - PUBLIC DOMAIN:
-
- MEX114.LBR - Contains an excellent Terminal Program (needs Jump
- Table edits to work on the C=128). A full set of Utilities and large
- set of Overlays for various systems and Modems are contained on several
- disks. The C=128 overlay has been installed on one version available
- on local BBSs, but only for the CBM 1670/Hayes Modems. It is loaded
- with set-up controls and toggles, for those who like this feature, and
- will Batch Transfer in several protocols that include ComPuserv's. It
- is very well documented and available on SIG-M Library Vol #218, 219,
- 220 and 241.
-
- IMP244.LBR - Another excellent Terminal Program with all the
- features of MEX - but most are automatic and transparent to the user.
- It also will Batch Transfer 128, 256 and 1K Byte Blocks and has KMD or
- XMODEM (Christensen) Protocols. I much prefer this one (its fool
- proof)... and have recommended CBM license it and adapt it to all CBM
- Modems. There is an C=128 overlay (I2C8-1.OVL for the 1670) and a
- converted version (IMP-128.COM) available on most local BBSs. The
- needed Utilities are included only in the LBR file - so get both. It
- is very well documented, but the overlays must be ordered from the
- Author.
-
-
- UTILITIES FROM THE PUBLIC DOMAIN:
-
- CONF.COM/HLP - The C=128 Configurator. These files MUST be on the
- CP/M+ Update Disk. It was released to the Public Domain on 21 Jan. 86
- by the author Von Ertwine and has been a lifesaver. The command and
- help file support the set-up of system:
- - 40COL: toggles on/off the 40 column screen (and eliminates
- random character errors).
- - BAUD: sets the baud rate for the RS232 Port.
- - BACK/BORD/CURSOR: set colors on the screen.
- - DATE: sets system date and time.
- - DRV: assigns Disk Drive device numbers to A:,B:, etc..
- - DUMP: dumps 16 bytes of memory from ROM in Hex from a
- selected address.
- - FEEL: sets key scan frequency.
- - HELP: types the help menu and instructions
- - MAP: maps the keyboard assignment by KEYFIG.
- - PARITY: sets byte character (ie 8/N/1, etc.)
- - POKE: pokes a Hex code into memory at selected location.
- - PRT(1 or 2): sets printer output to ASCII or PETASCII and
- selects character set.
- - REPEAT: toggles repeat keys on or off.
- - VOL: sets audible key-click volume level.
-
-
- NULU151.LBR - Menued and well documented LIB file utility. Makes
- and unmakes libraries with squeezed files. Has features for reading,
- extracting, squeezing/unsqueezing, making and erasing files. You will
- want to find the COM and DOC files seperately to get started (or get
- USQ.COM and DELBR.COM files to open this LBR).
-
- NUSWEEP107.LBR - Library file utility with some features not found
- in NULU. Well documented and Menued for ease of operation. Actually,
- both are needed and complement each other. Both will allow indexing of
- files and in one "sweep", extract only those files selected -
- unsqueezing as it goes.
-
- USQ/DELBR/BISHOW.COM - A nice set of individual LIB file utilities
- contained on all SIG-M Disks. Unsqueeze/Extract (ie de-library)/Read
- files in squeezed or unsqueezed format, respectively. BISHOW (or
- QSHOW) outperforms the TYPE.COM utility on the CP/M+ Distribution Disk.
-
- CPM3UTIL.LBR - Excellent set of CP/M+ utilities found in SIG-M
- Library Volume 234. Contains the following:
- - DISK3.COM: full directory listing and available space.
- - EDIT3.COM: Text Editor enhanced over ED.
- - IMAGE.COM: track by track disk copier, any disk format.
- - PASSWORD.COM: to protect the CP/M+ System in PROFILE.
- - UNLOAD,COM: converts Binary file to Intel Hex file.
- - VERIFY3.COM: checks all disk sectors - any format.
- - DISKED3.COM: menued sector editor for direct read/write.
- - WRTSYS.COM: writes boot to system tracks of disks.
-
- UNERA+.LBR - Poorly documented, it restores erased files.
-
- SUPERZAP.LBR - Full screen Disk Editor, with Menues.
-
- CPM3-CAT.LBR - Disk Catalogue maker.
- BRADFORD.LBR - NLQ Printer software like Fancy Font. Few fonts,
- not documented "free ware" - but worth it.
-
- COMMERCIAL SOFTWARE TESTS:
-
- WORDSTAR 3.3 - Latest version of the Word Processor standard. Do
- not bother with earlier versions. Good books are available to cover
- documentation needs.
-
- WORD FINDER - Thesarus for use with WordStar. Excellent to check
- for spelling, as you type the document.
-
- SUPERWRITER - Fine Word Processor with SpellChecker and
- Dictionary. Works with SUPERCALC2 to print full reports.
-
- SUPERCALC2 - Great spreadsheet software that has Data File Format
- Converter included for CP/M-86/80 formats. Works with SUPERWRITER to
- produce full reports.
-
- FANCY FONT - Excellent NLQ Printer Software in many Type styles
- and almost any ASCII file format. A very large library of Fonts are
- available, in sizes from 4-72 Point. Very well documented, Bit-Maped
- and S L O W !!
-
- TWIST & SHOUT - Sideways and Banner printing Utility for Dot-
- Matrix Printers. Few Fonts compared with Print Shop.
-
- TURBO-PASCAL - A MUST for any CP/M+ system. Compiler, editor and
- other utilities. Makes the Public Domain T-Pascal software usable.
-
- C/80 3.1 & MATHPAK - C Compiler and Utilities for C language
- programming. Well documented and recommended.
-
- GAMES - We tried ZORK II, Adventure 80, SNAKE, ELIZA and some of
- the other CP/M text games - with some limited interest. Not as
- exciting as the C=64/128 Arcade games, to say the least.
-
- COMPUTER CHEF - The main software of a set of four recipe disks
- and meal planners. As an amature chef I liked it - particularly the
- Chocolate Bytes Library. Auto-sizes recipes to number of guests.
-
- ZCPR3.LBR - Im still in the process of evaluating this MASSIVE set
- of Files (seven disks full) to replace the CP/M CCP and E X P A N D !
- the limited capability of the Operating System - DRAMATICALLY! It was
- written for CP/M 2.2, and will take a great deal of time to install. I
- will report on this seperately, later. I HIGHLY recommend that CBM
- take a long and serious look at this outstanding option.
-
-
- WRAP-UP OF THIS REPORT - TO CBM:
-
- We have taken the process of Beta-Testing of the CP/M+ Upgrades to
- their logical conclusion consisting of the preceeding series of
- recommendations to CBM for needed correction of several problems. The
- software tests are by no means completed - but will continue and be
- published as appropriate for unique software available as well as
- future CBM issues.
-
- Our recommendation that CBM fully investigate ZCPR3 implementation is
- taken seriously by Exchelon in California - it has promise of making a
- MAGNIFICENT MONSTER out of this 'Mean Machine'. The origional CCP is a
- mess inherented from an archaic CP/M concept. With its replacement,
- ZCPR3, the capability of the C=128 will be greatly expanded to include;
- Shells, Aliases, I/O Redirection, Flow Control, Named Directories,
- Search Paths, Custom Menues, Multi-Command Lines, MANY Resident
- Commands .... and Much More! With it we will realize the UNIX like
- Operating System capability from this MicroComputer, that exceeds any
- other available on the market today in this price range. A "MUCH
- Higher Intelligence - at a MUCH Lower Price" - indeed!
-
- On the Hardware Front...we do highly recommend that an expansion
- package be made available, from CBM, to add two more banks of 64K Bytes
- of RAM/ROM in the "Empty Socket". The upgraded CP/M+ BIOS should
- accomodate this capability. Your promise of a GEM capability will thus
- be realized...and the full utility of the C=128 for us, the BUSINESS
- COMMUNITY of USERS, will be greatly enhanced.
-
- We have enjoyed performing this extensive Research and Evaluation
- exercise for CBM, and their loyal following of Commodore Computer
- Users. We have recognized the enormous potential of the C=128, better
- than most, - perhaps better than CBM at this time.
-
