Ok, my friend gave me two DMC systems this weekend. Never heard of DMC and I'm hoping someone else has. The box is about 12" high, 19" wide and about 18" deep. The front panel has a POWER and RESET switch. It says "DMC" and under that "Division of Cetec Corporation". It also says "COMMFILE". I'm assuming that's the name of this system. On the back serial number sticker, one says model 125 and the other model 130. The difference seems to be in the number of serial ports and RAM each has. Both have two integrated 8" disk drives. Inside we find a card cage with 8 slots. The cards at first look like S-100 but upon closer inspection (and a count) I noticed that they actually have 60 conductors on the each side of the edge connector. On the component side, conductors 12-51 are common. The cards are about 1.5 times the height of a typical S-100 board, and the same width. The CPU board has an 8080 on it. There are two serial ports on the back of each, one labeled "OPERATOR CONSOLE" and the other "MODEM". I got two 8" floppies (hacked into double-sided) with the system. Only one seems to boot. I plugged a terminal into the operator console port and booted the disk (it only takes about 2 seconds) and get: READY (V7.0) and then a flashing cursor. Haven't figured out any commands yet, because anytime I type anything I get: ?? INVALID COMMAND and then the READY prompt. Anyone know what I've got? I don't know if my friend knows but he wasn't around when I picked them up so I haven't had a chance to ask him. My guess is he knows nothing about them anyway. He's been sitting on them for years and finally decided he was sick of them taking up space in his room. Any help would be appreciated.

So I also would be >interested in any information you find out about this machine! I don't have much, but I can give some of what I know. Ohio Scientific made, or so I gather, four 8 bit home computers - the C1P, C2P, C4P and C8P. Most of my info seems to be on the C8P, which was regarded as The Home Computer of the Future largely due to its ability to control your security system, electrical appliances (like lights), smoke alarms and so on, as well as being able to dial up the police when needed. The C2P, according to the little I have here, was a CIP with more ports, as the IP had but one. Thus the info I have on specs is mostly for the 1P, not the 2P, so I will give that in case it helps. Anyway, the IP is said to have been the first fully packaged home computer that you could just plug in and use. It came with either the MOS 6502 or Motorola 6800 cpu as standard (depending on your requirements) and had a CPU expansion board, allowing the addition of a Z80 or one of several other popular CPU's. It had a standard 53 key keyboard, upper and lower case letters, and 64 char by 24 line mono video. 4k or 12K RAM was standard, with8k BASIC in ROM. Sorry that I don't have more, but my interest tends to lie in the history, rather than the specs. Just for fun, it is worth noting that Ohio Scientific is noted for being the first PC Company to have a woman (Charity Engel Cheiky, I think) as President. Adam.

Challenger 2P

by thedm＠sunflower.com

I recently aquired a 1040STe and STf as well. It's a great machine, If you need a monitor for one I know where you can get a color 14inch stereo monitor for 85.00. This machine will do Slip, PPP and do just about anything a PC will do on the web, {with some upgrades} the Atari ST's were very cool machines I've found. If you need any info or help with the Atari, don't hesitate to ask, Its a wonderful fun machine. ---------- > From: Adam Jenkins <adam(a)merlin.net.au> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Challenger 2P > Date: Sunday, August 31, 1997 9:45 PM > > >John R.

Are you receiving this?

by kyrrin2＠wizards.net

CLASSICCMP READERS: Please pardon the CC. I'm still not sure that Tim is able to receive mail from me for whatever reason. Ok... here's the current status. I've used SYSGEN as you described, reset a couple of cards as needed to correct some mis-set addresses, and put everything back together. I've used AUTOCONFIG ALL /SELECT=(PU,PT,XQ,TX). This should have configured the tapes, the disks, the DELQA, and the DHV11. I then issued the commands: SYSGEN> WRITE ACTIVE SYSGEN> WRITE CURRENT SYSGEN> EXIT I then shut down and rebooted. However, the second TK50 still does not appear to be available under any of the device names. It should, I thought, come up as MUB0:, PUA0: or PUB0:. I cannot mount it under any of those designators. At this point, I am reinstalling OpenVMS 6.2 from scratch on another drive. I'll see what happens then. I've borrowed some documentation that covers SYSGEN, but either I'm not doing something right or I've overlooked something so basic that either one of us might take it for granted. Could the problems I've been having with the license management affect it? As soon as I get the hardware issues dealt with, I can -- FINALLY!! -- copy that stupid tape! Please let me know if you receive this in your E-mail box or only from CLASSICCMP.

help with some recent finds

by dastar＠crl.com

Ok, I picked up some keen stuff today that I'd like to hopefully get some information for. 1. Tektronix 4041 Computer/Controller. Now this is neat. Unfortunately it doesn't do a whole lot at the moment. First a description: its about 8" wide by 8" high (front) by 2' long. It has a built-in 20 column thermal printer and a DC-100 tape drive. The front panel consists of a numeric keypad plus some other special function keys, an LED display and some status LEDs. I opened it up and found that it is a 68000 based system. It seems to use an S-100 bus, since the cards have S-100 edge connectors. It has four slots, and two of the slots are filled. One has the CPU card with the 68000 processor. The other is a Standard I/O card. The two other slots are Read/Write Memory (RAM) and an Option Card slot. The front panel also has a slot for a ROM pack. The ROM pack is a tray that pulls out and has two ROM packs plugged in with room for 4 more ROM packs. The ROM packs included allow for BASIC programming. On the back is an RS-232C port and a GP-IB (IEEE488) port. It is circa 1981. When I first booted it up the printer started spitting out paper. The next time I turned it on only the power LED came on. I then turned it off and opened up the cover to examine its innards. I pulled each card and checked them out then replaced them. I turned it back on and this time got "SELF TEST" on the display. It never does anything after that. I got two manuals with it, and of what I've read so far, the self test should check all the controllers for the tape drive, the printer, the front panel, and perform other diagnostics, then show the ROM version, but it never does this. I'm wondering if a lack of a RAM card is the culprit. This system also came with an optional programming keyboard, which was just a full size keyboard for entering in programs. If anyone can shed any light on this sucker and what else it could do I would appreciate it. I remember seeing in a book I have a picture of the graphics output of some Tektronix computer on a screen. I can't remember what book this was in or even where that book may be. I wonder if this is the system that produced that output? 2. A Lynx 460 Floppy Drive Alignment Tester. It has two connectors for 8" and 5.25" floppy drives. It has all sorts of toggle switches on it for selecting the drive (1, 2, 3 or 4), the head (1 or 0), the track address, etc. It also has status LEDs to show, for instance, Amplitude, Radial, Head Load, etc. Not that I know what any of this means (not yet at least, I got it with manuals and the manuals have a nice introduction to disk drive theory of operation). Anyway, apparently you use this in conjunction with alignment disks. Looks like a cool box (it's very small, the size of a notebook) that will come in handy in years to come. Any further information on either of these would be appreciated.

Hard Disks

by healyzh＠ix.netcom.com

Hi, Last weekend I was lucky enough to find a pallet of Apple II stuff (2 complete systems, and lots of cool things), and amongst everything was a copy of a book called the "Apple II User's Guide" published back in '81 by Osbourne/McGraw-Hill. In this book under the chapter on Drives I found that it talks about three types of disks; Hard Disks, Winchester Disks, and Diskettes. It also has a picture for each, and it's the picture of the "Hard Disk System" that interests me. It appears to be a Rack Mounted enclosure for a Removable Disk pack. I can't see how many platters the pack has (the cover is white plastic), but I would guess between 2 and 4. It has four square push buttons (looks like the kind that light up), and two small lights. Basically it looks like a "Micro" version of the disk packs I used to use on Honeywell and UNISYS Mainframes. The photo was courtesy of "Cameo Electronics", and I can see their logo on part of the case. The text says the disks cost about $150 each and the drives between $3000-10000. All in all a very fascinating looking peice of hardware! I've never seen anything like them other than on mainframes, were these very common? Zane | Zane H.

As they were often more expensive than the cpu they were on they were not frequently seen on the likes of apples and s100 systems. They were more often seen on Novas, PDP-8s, PDP-11s and other minis. The larger multiplatter drives were even to costly for the smaller minis and were seen at those sites that had the larger PDP11s or even bigger machines. Back in 1980 a Hawk (10meg) was something close to twice the price of a complete NorthStar* Horizion with two floppies, 64k and terminal. Two years later non removable drive would be quite cheap compared to that but removeable platter drives would still command a premium. Now a Zip drive compares to common IDE hard disks. Allison

1. After getting slightly sidetracked on the way to Bruce's a couple weeks ago - I'm back ;). 2. Apple III experts - what's the difference between an A3M01 and an A3M02? I'm assuming 01 is the "drop-fix" motherboard and 02 is the fixed version. Does anyone have software for a MS Softcard III? 3. Do you need Apple II parts? I have too many. I have II+s and IIe's (working and not) lots of Monitor III's. Assorted manuals for Apple II and III. Tons of disk drives. If you're looking for something and I have it it's yours for the price of shipping. I have a number of badly broken system which will ultimately be scrapped but I'll be pulling pieces so... I'll eventually put together a list but I need to make some room now so just ask. I'll also be trekking down the coast 2nd week of September so if you live along I5 in OR/WA or 101 in CA I might be able to deliver. 4. Classic Computer HOWTO's. I've been sitting at home for a week inventing things to do and started writing a how to document detailing drive alignment for various disk drives (not even close to ready yet). Anyway, seems like a cool idea for those of you who know how to do things to detail them in a howto and help improve everyone's know-how. People keep asking, for example, how to convert TV to composite output. If you've got nothing better to do ;).

VAXstation works!

by rcini＠classic.msn.com

Well, I got the VAX working last night. It has a melted power cable that I had to rebuild. It seems to boot Ultrix, what seems to be a Unix variant. Time to play... Also, can anyone point me to any FAQs about the VAXstations? Rich Cini/WUGNET rcini(a)msn.com

Bouroughs Documentation

by IVIE＠cc.usu.edu

> Anyone interested in any of the Bouroughs manuals given the lack of > precise data on what they are? I'll probably pick up most of it anyway but > if I know someone wants the stuff, I can be a little more liberal in what we > take. Yeah. I've had unhealthy relations with a B-800; if there's anything about the B-800 I'm interested. Other things to look for are COBOL language manuals, NDL language manuals, and manuals covering operating of MCP and CANDE. I'm interested in all/any of these. BTW, the B-80 is close enough to the B-800 to be interesting as far as I'm concerned... Roger Ivie ivie(a)cc.usu.edu PS: Burroughs had a really good COBOL compiler on the B-800, it just took _forever_ to compile anything...

DEC Assistance

by kyrrin2＠wizards.net

Tim or Allison, I could really use your help. Tim, I think something in the mail system may be preventing my messages from reaching you. I have O-VMS 6.2 up and running. What I need is someone else with a MicroVAX to create an RX50 floppy, initialized with VMS, with VMSTPCE (unzipped and ready to roll, ideally) copied to it. I cannot seem to transfer it from my PC, via PUTR and VMS's EXCHANGE, to save my life. This evening, I will try installing TCP/IP services on the VAX and try to FTP the appropriate file from its resting spot on my server. However, I'm not sanguine about the results given my difficulties over the last few weeks. Sheesh... it should NOT be this hard to do a simple binary tape copy! If tonight's effort fails, and no one else can help, I'll just install Ultrix and try it that way. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin2(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.

Kaypro II help needed

by SUPRDAVE＠aol.com

I decided to drag out my kaypro II for testing/cataloging/photos and noticed it's even worse than before. previously, i was able to boot a cpm disk but got no keyboard activity. now, it powers on, spins the floppy a few rotations, then prompts to place a disk in drive a: and no more than that. hitting the reset button didnt do anything. it keeps coming back to the same screen. while typing this note, i noticed it finally booted off a floppy in about 5 minutes' wait and now i'm getting no keyboard input (not even ^M or ^G) and the floppy light is staying on but not spinning. i do get an a: prompt though. someone mentioned the keyboard controller chip missing, but it's there. this machine has two half height floppies which i assume incorrect. would full height pc/xt drives be "correct"? what should i check now? david

A McDonnell-Douglas Micro-6000?

by IVIE＠cc.usu.edu

> Anybody know what this baby runs??? I heard in passing that they used > to run PICK on it. I think PICK is some kind of manufacturing software > but what was/is the operating system? PICK is the operating system. PICK is a combination operating system/programming language/user environment. It was created by Dick Pick on a military computer (I think one of those militarized UNIVAC thingies) and ported to a variety of other machines. AFAIK all legitimate ports were done by Dick Pick himself, although the book I found talks about people cloning PICK without Dick's permission (since this is a book of the "PICK rah, rah, rah!" variety, this is said to be a Bad Thing). Personally, it looked to me like there were holes in the PICK system you could drive a truck through; security seems to be done mostly through obscurity. Roger Ivie ivie(a)cc.usu.edu

Does anyone have an explanation of what the Unibus pins do?

I was curious. I have the pinout in the 11/44 book, but it doesn't say what any of the pins do. I have something I want to try, but to try it I'd need to know what the pins do.

This is an excellent idea. So far, I only have one interested American, but if others get in touch with me we will try to organize something. Be aware, though, that things will probably take some time. I don't have ready access to the attic in question and before we even start planning I will need to meet and discuss with a few people. /F

bci-20.htm

by dseagrav＠bsdserver.tek-star.net

BCI-2000 bci2000 Unibus Adapter for the PCI Bus _________________________________________________________________ The BCI-2000 Unibus Adapter enables Unibus devices to be connected to workstations supporting the PCI bus. The BCI-2000 supports both PIO and DMA Unibus data transfers as well as providing support for all four Unibus interrupt levels. The BCI-2000 consists of a single slot PCI controller, a dual-width Unibus cable adapter module, and an eight-foot shielded interconnect cable. The PCI controller occupies a single PCI slot. The Unibus cable adapter installs into the Unibus connectors A and B of an expansion chassis or user's equipment, replacing a Unibus cable. The BCI-2000 provides complete support for: * Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. * Unibus DMA data transfers including read word, write word, and write byte. * All four Unibus interrupt levels: BR4, BR5, BR6, and BR7. _________________________________________________________________ Features Provides a migration path. The BCI-2000 allows users of Unibus systems to migrate to the new high performance PCI workstations and retain their existing Unibus I/O devices without loss of function or performance. High performance. Unibus PIO and DMA data transfers occur at maximum Unibus speeds -- throughput is limited only by the Unibus device. Cost savings. The BCI-2000 provides users the choice of low cost, high performance PCI workstations while retaining their existing investments in Unibus hardware and software. Easy to install. The BCI-2000 allows multiple I/O devices to be connected to a workstation while occupying only a single PCI-slot. Easy to maintain. The BCI-2000 executes a comprehensive set of diagnostics to automatically verify module operation. _________________________________________________________________ Description PIO Transfers The BCI-2000 supports the four types of Unibus PIO data transfers including read word, data-input-pause, write word, and write byte. The entire Unibus address space is available for access by a PCI host. DMA Transfers The BCI-2000 provides full compatibility with the three types of Unibus DMA data transfers, including word read, write word and, write byte. Single and multiple data transfers are supported. Interrupts The BCI-2000 passes Unibus interrupts to the host for service if interrupts are enabled by the host and the interrupts are higher priority than the priority established under software control. The BCI-2000 stores the 8-bit interrupt vector in an internal register that is referenced by the host to determine the interrupt service requested. Unibus Termination The BCI-2000 provides Unibus termination for one end of the Unibus. The user must ensure the Unibus is terminated at the end of the Unibus within the expansion chassis or the user's equipment. Unibus Parity Unibus parity signals PA and PB are terminated but otherwise not supported by the BCI-2000. _________________________________________________________________ Software Compatibility The BCI-2000 is not supported under existing OpenVMS, Ultrix, or OSF/1 operating system software and requires software drivers to support the features offered bu the BCI-2000. Consult our factory for more information. Specifications Physical Dimensions PCI controllerSingle width card, 6.875 inches by 4.2 inches (17.46 cm by 10.67 cm) Unibus Cable AdapterDual-width Unibus module, 5.s inches by 2.3 inches (13.s cm by 5.8 cm.)

Half an attic full of old computers (help save them!)

by ekman＠lysator.liu.se

Hello! I am currently working for a company in Gothenburg, Sweden that used to be the Scandinavian importer for Sord computers (a Japanese company) during the eighties. Their attic is full of old stuff, most of which the boss would like to throw out, and which he would unless a couple of employees disagree with him. Not only are there computers and peripherals, but also loads of documentation and software. I had a discussion with the boss recently and asked if it would be possible to ship the stuff to interested parties if I would do the work free of charge. No such luck. I may be able to persuade them to let the stuff for free if the receiver pays shipping, however. But shipping from Sweden is expensive. Thus, I am now trying to see if there is any interest in having any of this for the cost of shipping. If there is, I will try to make a definite deal with the company and then make a list of what is available. I am afraid that if nothing is done soon everything will be dumped into a container. If you are potentially interested, please reply directly to me (ekman(a)lysator.liu.se). If you have any questions about Sord computers in general, reply to the mailing list. /F PS. There will be no IS-11 or M-5 stuff (I will be reserving anything such for myself) but probably several M-23 and M-243 and who knows what else. Possibly also hand-held GRiD terminals and maybe the odd PC compatible. I know there are some UNIX minis, but the company may want to keep these since they still have customers using such. Everything will be adapted for Swedish electricity net (220 V).

PDP-11/44 is Finally Up!

by dseagrav＠bsdserver.tek-star.net

It works. But I shouldv'e noticed no termination right off... That was a stupid mistake. Anyway, now that it's up, I get to find a more permanent home for it- This building goes away at the end of the month! We're looking at Jeff's garage. I was telnetted into it last night. Once I figure out how, it goes up for public access. Anyone know of PPP for RSTS/E? :) Or I could always re-write the TCP/IP protocol in BASIC-PLUS... Oh, and we're going to take it apart to move it this time. Give Jeff more opportunity to bust the OTHER foot... And less work for me! How much does a DEC cabinet weigh empty?

[[ Editor's note: Obviously, you need one of the above-mentioned portables to make use of the DVI... ]] It needs a special cable that I have seen for sale on comp.sys.tandy, and at the for-sale listing at: http://www.value.net/cgi-bin/cgiwrap/~thedock/c100sale.pl [[ Editor's note: this is a cgi-program accessable from the "For Sale" link at: http://www.the-dock.com/club100.html They also have a wanted listing and a guestbook! ]] It *does* require a boot floppy disk, I believe these are still available at Radio Shack for a few $$$ apiece (at least in the US... not sure about other countries) I have a boot disk for the DVI that boots the Model 100 -- too bad it doesn't seem to work with my T200. :-( I do have the pinouts for the cable, but the connection to the M100 was a specially wired 40-pin DIP cable, that I've heard is mongo-painful to try to build yourself (and, of course, RS doesn't stock those IIRC). The cable for the T200/T102 is easier to build with 40-pin IDC connectors and ribbon cable (I successfully converted an IBM-PC Clone IDE data cable) If you wish more information on this or most anything else from the "Model 'T'" world, just let me know.

IBM PC/Jr??

by foxvideo＠wincom.net

I am trying to revive a PC Jr. At power on I get two beeps, no video either on the IBM monitor or through the RCA connector. I have tried removing plug-in boards except for power supply, with same results. Also tried two different PC Jr keyboards, plugged in, same results. Does anyone recall what two short beeps indicates on an IBM PC/Jr? Thanks Charlie Fox

RA81 Rides Again! More problems.

by dseagrav＠bsdserver.tek-star.net

This is getting to be a real pain... Sometimes it boots, most times it won't. Usual response is I say b du or b du0 It hits the disk twice, and halts at 050110. I have run the RA down all it's diags in the manual, no faults. Same for when it boots. The UDA50 does running lights too. Doesn't matter if I use A or B. Only difference there is A lights up sometimes and B doesn't. Cables look fine. What's going on? Does it just hate me? Also, when RSTS/E does come up, it sometimes traps to 4. Timeout/sysfail vector. Something says this drive is going...
