Well CCP is a user interface as is command.com, changing out command.com for Win3.1 still doesnt change the fact that it's a DOS OS with a GUI instend of Command line.

Great. I'm looking forward to getting them. I haven't found anything that can read my SB-180 disks so I hven't been able to transfer the ZCPR to anything else yet. I think it would be cool to get it running on a PC! I stuck out. I looked through my ZCPR docs and book but none of them tell what the differences are between ZCPR3 and ZCPR 2.2. "ZCPR, The Manual" only gives the differences between ZCPR3 and CP/M 2.2. I don't know anything about the earlier versions of ZCPR so I guess I'm no help. Joe > >Regards, >-dq > >

B&C Microsystems up600a software, anyone?

by ethan_dicks＠yahoo.com

I keep meaning to ask this... I have an ancient B&C Microsystems universal programmer, model UP600a. I'm running version 3.0something of the software. The largest device I can program is half of a 27040 at a a time. At one point in the past, I tried to download the newer personality files from the B&C Microsystems BBS, but the file was corrupt (full of text garbage, as if caused by either a rampant disk overwrite or a disgruntled employee or customer). Does anyone out there happen to have one of these beasts? I'd love newer software that supported newer devices, both memory (EPROM) and logic (PAL/GAL, etc.). Thanks, -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away. The permanent home is: http://penguincentral.com/ See http://ohio.voyager.net/ for details. __________________________________________________ Do You Yahoo!? >From homework help to love advice, Yahoo!

Nupon LTS-4, terminal server

by ncherry＠home.net

I have a Nupon LTS-4 terminal server and I'm wondering if anyone has software for the beast. I managed to find software for it but the software appears to be for a model with a different serial interface (a newer Cirrus chip, this one has a CL-CD180-10PC-C). The symptom is if I set the buad rate to 9600 it runs at ~7K (or about a 20% error). I'm not really proficient at 386SX disassembly (yet) so I can't find the rate table to adjust them.

FS: Heathkit EC-1

by badger＠vbe.com

I have a Heathkit EC-1 Educational Analog Computer with original manual I'd like to sell. The computer is in unknown functional condition (I don't know if it works right or not) but it looks pretty good. I'd guess I'd have to sell it as unworking. All the parts are there but some of the knobs are "stiff". This EC-1 was in storage since the 1970's ...... it was with some electronic test equipment I purchased at a surplus sale at a college. If you have an idea of it's worth .... either to a collector or as a parts unit please email me at badger(a)vbe.com Thanks, Mike Melland, W9WIS (Oshkosh,WI)

This system included DOS ver. 2 and BASIC ver. 6, Release 3 >and is also copyright 1977. Actually no. NSdos was a simpler file system but actually robust and very fast. It lacked editor/assember/debugger but did have a good set of diags for ram, monitor and NS* BASIC. Which for it's time was pretty good. Also it could boot in as little as 4k of ram and run basic in 24k. Allison

ultrix disktab entry for an RF73?

by thompson＠mail.athenet.net

Greetings I have an elderly version of ultrix (4.2A) which knows nothing of disks of mind boggling capacity such as the two gigabyte RF73. Does anyone have a later version of Ultrix with the dimensions of this disk specified in the /etc/disktab file? (p.s. has anyone else noticed that Altavista seems to be lamed deliberately or otherwise so that Linux or Netscape clients can no longer search properly? I have noticed this for a couple of weeks...I go into work and use Internet Extorter on NT and everything is fine.) Thanks in advance Paul

Cadnetix

by jjackson＠salsa-digital.com

OK. I've been quiet long enough, I think. <grin> Now it is time to ask a question. I have an old Cadnetix 50000S workstation. It still works - sortuv. I would like to find a replacement board for the ailing one (graphics), or locate technical manuals on this beastie. What is a Cadnetix 50000S? It is a CAD workstation that performs Schematic Capture, PCB Layouts, runs Berkeley unix (I think it's Berkeley), uses a 68020 processor, and can still run rings around many Windows CAD software packages... ok, just barely. <grin> What I'd _really_ like is to find one of the Sun-2 Cadnetix platforms. (I think it was a Sun-2 - it's been a while folks.) Now, these puppies - they could really scream! Anyway, I saw a bit on the 50000S platforms a while back - was just wondering if anyone might still have one and want to swap something or other. I know where there is a Cadnetix burial ground - it's just that I'd have to pay homage to the groundskeeper. Regards, James Jackson

ZCPR is a replacement for the rather anemic CCP (console command processor) and a few additional utilities. Of ten the BDOS and BIOS are unchanged and that is the core of CP/M. The CCP is user interface. The DOS analog of that would be Windows3.1 is not DOS. See the point!

Hello from a new member

by jjackson＠salsa-digital.com

Hello, I found this group while looking for information on an archaic computer system. I have several systems at home that may qualify as 'classic' computers... a Heathkit 6500 computer trainer (I think) with documentation SWTPC 6800 - in storage with a hefty 4k RAM Amiga 1000 Amiga 4000 ...and a few others. I am going home tonight to look at them and see if I might have something of interest for someone else. Intel (360?) Multi-Bus I system used for development... complete with software and manuals. I also have much documentation. I'm a packrat when it comes to User's Manuals. But it is now time to clean out the storage room. <sigh> I have information for those of you with Amiga 4000's for repairing your A3640 CPU boards. This is on my web site. Also - for replacing the capacitors in the Audio section. (This applies to any of the Amiga series. They used polarized caps in a uni-polar output stage of an op-amp.)

Old HP Stuff Available

HP SRMs (pre-Unix - will run HP BASIC) available Some CPUs, some hard drives. All have HPIB ports. Possibly some printers. and HP 340's (diskless) with ethernet, HPIB, serial, & parallel built in. Will run Unix. Your cost on any of these would be shipping plus packing at Mailboxes, Etc., plus $10 per item for us to haul them from the basement, put them in our trailer and tote them to Mailboxes. If you're interested, let me know ASAP, as they go to the scrapper on Monday, 10/30/00 when the company's lease runs out. If you're familiar with HP stuff and want details, please contact me. If you're not familiar, I can't help you much, although I *can* read numbers >from front panels if there's anything in particular you're looking for. Just trying to save some good, old hardware from the shredder. It's located in Lincoln, Nebraska, so if you're within driving distance this weekend, we can probably arrange something to save you shipping and handling.

We only just in the last few weeks finally got a listing of the full DPS-8/M instruction set (or was it the Level 68?) posted to the web. So at least one of the most important resources for getting started is now available... -dq

Using Toshiba XM3301B scsi cdrom on old MACs...help?

by claudew＠sprint.ca

Hi Bought several XM3301B Toshiba CDROM drives very cheap. (I am looking for some caddys by the way...anybody got some they wanna throw out?) Trying to use these on old compact MACs and MAC IIs using Mac OS 7.5.5 Used a driver that sees cdrom drive (icon with scsi id for drive appears on os startup) as soon as iso9660 format cd is inserted, it reports that it cant read the disk, it reports the size of the data used up on disk and asks if I wanna format it or eject it... All support files are in the extensions folder (high sierra, foreign files acces...etc...) I am using a driver that says it supports the xm3301 is the readme file. (something from lacie company...off a www page with older MAC drivers.) I have tried apple generic cdrom support. Does not see the xm3301b. (whats the b for anyways?) I have used a newer Pionner scsi cdrom with pionner driver on the same system with success. The newer pionner drive with same driver/support file does same thing.... This must be something simple I cant see...but I am no MAC OS expert... Thanks for reading Claude

Using Toshiba XM3301B scsi cdrom on old MACs...help?

Probably the block size. The older Macs require the blocksize on the CDROM to be set to 512 bytes, as do older Suns and SGIs (newer machines work with normal 2048-byte blocks, and issue a SCSI command to reset the size). To fix this requires some minor surgery on the drive. This works for XM3301 and XM3401, but not XM3601 or later, BTW. I believe it works for XM5401 but I can't be sure about others. On the 3301/3401 PCB, there are two solder pads near the rear right corner. Each looks like two semicircles bridgeed together, and they might be labelled 0 and 1 -- if not, 0 is the one nearest the edge of the PCB. The default setting (for PCs) is for 2048-byte blocks. Cutting the bridge between the two halfs of either or both pads gives you 512-byte blocks; the resulting three possibilities are supposed to be for different systems: open, open Sun bootable open, shorted SGI bootable shorted, open generic 512-byte shorted, shorted normal 2048-byte (default) I've fitted a DIP switch to all my old Toshibas, so I can move them between systems fairly easily. -- Pete Peter Turnbull Dept. of Computer Science University of York

If you have 3-phase power, you'll likely be feeding a breaker box from two of the three phases, which would then be 120 degrees apart. That would, I believe, technically be 208v, not 220v. It wouldn't really be 220v center-tapped, though, at least not the way I'm used to thinking about it. -Dave McGuire

Free Epson JX-80 Color Printer & Summagraphics graphics tablet for Z100 in Ann Arbor, MI

by whdawson＠mlynk.com

These are free for the cost of shipping from Ann Arbor, MI. Please contact me off list if interested, and I'll supply the owners email address. Bill ? Your computer will do far more than you ever expected it to, and that won't be enough. Pournelle's First Law Dear Bill, Way back in February you put in a bid on my Z100. As you no doubt surmised, you were outbid and the Z100 went to a collector out in California. For your information, the winning bid was $350 and that was just for the computer and monitor. Looking over my basement recently I came across the two other items that were part of my Z100 setup, namely the JX-80 printer and the Summagraphics graphics tablet. These are boxed up in their original cartons, complete with documentation and ready to ship. You didn't get my Z100, but I thought you might want these other beautiful vintage items, still in good working order. You can have them for the cost of UPS shipment. The JX-80, boxed up, weighs about 25 lb. The tablet, boxed up, weighs about 10 lb. I'm in Ann Arbor, Michigan, which is about a 5 hour drive from Washington, PA. (Shipping should be less than $20). If you ever get your hands on a working Z100 I'd be glad to send you my Blokpix software at no charge. I quote here below the text of the description I sent out to you about this equipment. ------------------------------------------------------ Additional hardware supported by Blokpix is a Summagraphics graphics tablet with a 2-button stylus and a 4-button cursor. Attaches to the serial port. The active surface of the tablet is 12" x 12". Also an Epson JX-80 color dot matrix printer, which we used to print out our designs. Attaches to the parallel port. I still have a few unused 4-color ribbons for this printer, but they may well be dried out by now. Such ribbons can be reinked. There are a couple of places that do this kind of reinking. Epson no longer makes the ribbons, but you can still get black ribbons that work on it. These are for MX-80 or FX-80 machines. I'll be glad to throw in a handsome custom-designed lucite printer stand. This is a good workhorse 9-pin printer, still working fine. The most interesting software is that which I wrote myself. I have a graphics program called Blokpix that my wife and I used for years to design repeating designs for the fabric, apparel and wallpaper industries. You can have this. I even wrote a manual for it. I also wrote a demo program that displays graphic designs until you stop it. It can be controlled by writing a script. You can have this program along with the script I wrote for showing off our designs at trade shows. This makes a nice display. ------------------------------------------------------ If you want the lucite stand, that will have to go in a separate box. It would add another dollar or two to the shipping cost. Bill, please let me know soon if you would like these items. If not, they will go to the local recycling center where they will be cannibalized for valuable metals. At least they will not go into the landfill. But I'd much rather see their working lives extended by a caring collector like you. Bob

TRS80 PT210 terminal (original owner/manual works) $10 TRS80 100 portable $10 (needed 2 keys fixed now ok) TRS80 102 portable $10 (oxydation in power connector now all ok) 1 box full of TRS80 COCO stuff (coco, drives, interface etc...) including old RS catalogs from early 1980's $5 1 SCSI CDROM tower with 4 NEC caddyless 2X CDdrives $10 (not true vintage but good find IMO) 1 Xtra clean MAC SE complete $10 1 Eprom programmer PC card/zif socket $10 I am still hunting for a TRS80 model III.

Pinout signal connector + specs for NEC JC-1216DFA monitor?

by claudew＠sprint.ca

Hi Hate to throw this one in garbage, it's like new. Looking for pinout for signal and specs for a (1985 production date) NEC JC-1216DFA COLOR CHARACTER DISPLAY monitor. Looks like a standard ttl color but its got a 8 pin (2 rows 4 pins with 2 top ones spaced for polarisation with DND stamped on it) connector that I have only seen on old (1970-1980) video camera equipement and such. Never seen this for a computer video signal connector. I looked inside and judging from the chips around the input connector looks like it's ttl color. Did not bother to trace circuit more to figure out pinout. Taught someone would know... Before I throw it out or give it away, I want to know more, see if it can be used in some way for me... Thanks for reading Claude

MULTICS Installation, Halifax

by dhquebbeman＠theestopinalgroup.com

Hello, I've gotten mail from the guy who is supervising the decommisioning of the Canadian DND Multics System at Halifax. Not much new, but it's a little clearer in that all someone needs to do is attend the auction and buy it and bring it home on a truck. At least I doubt any "schools" will bid on this, if they do, they'd have their hands full. -dq ---------------------------------------------------- Douglas, I'm supervising the removal of our MULTICS system here in Halifax. John Macleod has indicated that you were interested in the details. On 13 Nov 2000 we will load the 5 CPU system along with FNP's etc. onto a truck destin for Crown Assets disposal. Crown Assets in turn offers the equipment to school projects then publicly auctions it off. We were planning to cut the serial cables to expedite the removal of several hundred cables under our computer room floor. The drives will be held locally for destruction (Security issues) but replacments could be available from GENTRONICS. If you have any questions let me know.

Timex Sinclair stuff for sale

by kevskvk＠inx.net

I was sent this adress by somone at another comp users group..I hope you can post it or pass it on..and I hope no one is offended I have recently found, while helping my landlady in her warehouse in Brooklyn, the following Timex Sinclair stuff. It all appears to be new, or unused, though many of the boxes are beat up from being moved around in a messy warehouse for years. Some of the boxes are very clean though. (TEN) Timex Sinclair 1500 computers..eight of them complete in (if rather beat up) boxes, two out of box. All of them new..never used. in original wrapping. (TWELVE) Timex Sinclair 1000 computers, Mint, New in unopened boxes. (THREE) Timex Sinclair 2068 Computers, new, out of box..without accessories attached, although I have found some power supplies and cables lying around loose. (TWO) 16K Ram Modules #1016 one in box, one out. Six plastic carrying cases for the 1500's (I think..the are little molded cases that say timex sinclair on them) some assorted TS software on cassette tapes, in original wrapping..(will check titles if interested) A whole lot of Timex 2040 printers, Alphacon 32 printers and cases of printer paper for both. All mint, new in unopened boxes of twelve. A reasonable offer...for anything anyone interested? thanks Kevin Skvorak kevskvk(a)inx.net

Splitting binary files for burning EPROMs...

by ethan_dicks＠yahoo.com

OK... so without taking the time to write a C program to do this for me, I have this binary file that is a memory dump of 256KB saved on a 32-bit machine.. I need to output four files, 64KB each, that are the component bytes of that memory space. I know I can write a program to do this. Are there any handy tools lying around so that I don't have to?

Q-bus cards available.

by Mzthompson＠aol.com

A good while back I hauled home what was the control box of an 8" floppy duplicator. The information of the box: Formaster Corporation 1983 Concourse Drive San Jose, CA 95131 Model 4400 I hauled home only the control box thinking the case might come in handy for some project. Earlier I opened it up and found a card cage full of what I assumed at the time was Q-bus cards. Now with the aid of the Field Guide maintained by Megan, I have identified the main card as a Q-bus LSI-11/2 CPU 16-bit card. I have no need for the cards and thought some might be of use to those on the list. A couple of the cards were made by Formaster, so doubt much demand for proprietary cards, but are included anyway. Cards 1-4 are dual height and 5-7 are quad height. So here is the list: ---------------------------------------- 1) M7270 KD11-HA LSI-11/2 CPU 16-bit Q-bus ---------------------------------------- 2) National Semicondutor Memory Systems card Has 4 rows of 9 4116's, so 64k Numbers on the card: 55110358-003C 980103858-001 REV L ---------------------------------------- 3) Sigma Information Systems This card appears to be a disk controller. It has 4 WDC TR1865PL controller chips on it and there are 4 ten pin header connectors on the card edge. Numbers: Assy 400200 CPX-6-0 ---------------------------------------- 4) Formaster Corporation I would say this is a proprietary card. Only meaningful number 003-30026-01 It has a 50 pin header connector and a 16 pin header connector. ---------------------------------------- 5) Acorn Systems memory card Has 8 rows of 18 4164's, so 1 mb Numbers: Copyright 1981 30019-01 ---------------------------------------- 6) Acorn Interface and ROM card I am guessing on this one. I say interface because has 4 50 pin header connectors and 1 34 pin header connector. IIRC, the 34 pin went to the front panel control board. It also has 4 EPROMS (24 pin) with ID stickers on them (Formaster) ---------------------------------------- 7) Formaster card I would say this is a proprietary card. Only meaningful number 003-29978-01 It has two 50 pin header connectors. ---------------------------------------- If you would like one of these cards, then here is the game plan. 1) Send an email reserving your card(s), first come first served. 2) I will not ask any specific amount for these cards. I will ask that you send something to cover a little of my time and the trip to the post office. I'll leave the amount up to you. Hint: Priority Mail stamps make nice tokens. 3) All cards will be shipped by Priority Mail, one card to a box. So send a $3.20 stamp for each card you want. Your card will be properly packed and mailed back to you. 4) Any cards reserved and no stamp received by October 15th will be 'unreserved' and tossed into the recycle pile.

Also true. I'll be guessing because the ROM sockets are not numbered on the board. :-( It's a VAXstation/MicroVAX 2000, if anyone happens to know what the EPROM byte order is.
