Well, I feel a bit like Michael Jordan and Magic Johnson, but "I'm back..." I've been fighting a few demons, some still unsuccessfully, but I feel like I can devote more time to my beloved hobby now... The collection has grown a bit, and shrunk a bit :-), some given away, some sold, some gotten free, some purchased (are there any other ways? :-)). Some stuff will continue to leave over the next few months as I settle down a bit ... So, to keep on-topic, what have I gotten lately? - A SWEET Heathkit H89, with manuals, disks, etc. (Yes, I'll be contacting Tom off-list). This was bought from a man in Kansas, who was the original builder, and even included the original receipts! He kept great records, and passed it all on to me. Cool! Now I just need to find some blank 5.25" hard-sectored disks to make backups of what he sent me. - A couple of Motorola Single-board computers, 6802D5 and 6800D2 I believe - An Intel SDK-85 -- Needs work on the keypad, but OK otherwise - A Xerox 820 (CPU/Monitor, Keyboard, 5.25" floppy drives), with disks/manuals/spare parts. - An Apple IIe "upgraded" to a IIgs -- This is basically a IIe case, but with a ROM 01 IIgs motherboard, and a special back plate for the IIgs ports. Also replaces the IIe logos on the case with "IIgs" ... Very nice! - Various Apple II stuff -- CMS SCSI cards w/ manuals and disks, A "Quickie" hand scanner for the IIgs w/ manuals and disks, RAMfast SCSI card, Zip GSX accelerator for the IIgs, Syquest removeable 44MB drive for the IIgs (not Syquest drive, but uses Syquest 44MB media), High-Speed SCSI card, various software - PowerMac 8500 w/ 500MHz G3 (1MB cache) upgrade -- Yeah, not vintage, but a sweet deal! :-P Anyway, thanks for letting me ramble ...

TRS-80 Model III

by foo＠siconic.com

I am trying to get a TRS-80 Model III working. When I turn it on the disk drive spins for a while looking for a disk I presume. All I get on the screen are wispish diagonal lines as if the horizontal hold is all whacked. I managed to unstick one of the video adjustment knobs on the left underside but all it does is affect the brightness level. The other one requires a screwdriver to move at all (shimmying it up and down) and does not seem to affect the display. I haven't opened it yet to see what adjustments are inside. I'd rather not, but there don't seem to be any adjustment pots accessible from outside the case. What's weird is that I have access to a bunch of TRS-80 Model 3's here at the ACCRC and pretty much all of the ones I have played with so far are basically "dead" in this manner. The one I'm working on just came in today and is in the same state. Also, the video knobs on the left underside are all stuck on everyone I've tried to get working. What is the deal with that? Do they get rusted over time or something? Very annoying. The fact that the disk drive spins up when I turn it on is a good sign I hope. Any help on this would be appreciated. I know next to zero about the TRS-80 series.

Sorry to use the list for this, but I lost some older emails, and no longer have the email adresses for you... Gene/Toth, Remember those PS/1 diskettes I told you would be coming 4 months ago?? They're finally sent (thankfully, your mailing addresses were stored separately from my email), along with humblest apologies... You may flame at will... John, Hard to believe I am so inept as to still owe you for the DEC LN03R stuff you sent eons ago.... Do you have a PayPal account? If not, the money will be sent in tomorrow's mail...

More NeXT Stuff

by jrkeys＠concentric.net

After digging into the boxes I got Thursday I found over 150 3.5 FD with various Next software on them and 12 CD's with Next software. Also I got 10 optical disk in cases for the Next along with a Pinnacle Micro external SCSI optical reader, model PMO-650. Got two sound boxes that were in parts and need to be repaired. Will put together a list of the software and send it later.

RL01 termination pack pinout

by classiccmp＠hexamon.org

Just to clarify, the following is the pinout of a terminator that works with an RL01 drive. It *should* work fine with an RL02 since the same interface card works with both, so unless there's some oddity about the RL02, this should do the trick: Opening the pack, there is a single large resistor pack, 40 pin. Looking at the back of the resistor pack (i.e. looking at the outside of the RL01 drive connector) the pack is marked with pin numbers; pin1 is at the bottom right, pin 2 is at the top right, pin 39 is at the bottom left and pin 40 is at the top left. Pin 39 has been cut. All other pins are connected. The resistor pack part number is 13-13242-00 SSM 7934 Neither side appears to have commoned pins. Each opposing pair of pins has 160 ohm between them (i.e. between pins 1-2, 3-4, 5-6 etc.) Obviously 39-40 is open circuit. I think it would be easy to make using a 40 way pcb-mount idc header with some shrink sleeving as the terminator isn't subject to any mechanical strain (unlike the cable). You could then attach this to the 40-way IDC socket which normally plugs into the DEC connector on the inside of the drive, and you would then just be using the external DEC connector as a seal to stop dust, etc from entering the unit. Even though the RL01 seems quite tolerant to the ingress of dust, (some of the maintenance procedures involve running the drive the the covers off) it doesn't do to take any unnecessary chances with kit this old. Hope this helps, Francis ---- Patrick Finnegan wrote: >I'd much appreciate that if possible.

reviving a HP 9000/310

by rumi_ml＠rtfm.hu

Hello! I'm currently trying to make an old HP 9000/310 machine work. Some information about the machine and the status of the "project" can be found out at: http://paranoia.rulez.org/~rumi/hp310.html What I currently need is either a way to crack into the HP-UX that is already installed on the box, or a floppy set (== images which can be written to floppies) of HP-UX that would run on this machine which sports a Motorola 68010/10MHz CPU, 2MB RAM, and a HP9153C 40MB HP-IB hard disk drive / 3.5" floppy drive combo. If you have such floppy images, or could help me with any software, documentation, or information regarding this system, please don't hesitate to contact me via email. If I succeed, I'm planning to put a nice webpage together about the system, with pics, history, infos, etc. Thanks, Szabolcs Rumi -

PDP-11 boards

by uban＠ubanproductions.com

Hi Patrick, I am very interested in the 11/40 board set. And if you want to get rid of one of the core boards, that would be fine too, but not a requirement. I happen to have an 11/23 CPU board somewhere, which I would be happy to trade you along with that RL02 terminator for the 11/40 boards (and possibly one of the core board sets). --tom At 07:38 PM 8/27/2002 -0500, you wrote: >I managed to grab a whole bunch of UNIBUS boards without knowing what they >were today, and found out that they are basically the boards to an 11/40 >CPU.

If you looked in the end of the remote, you could see the metal rods (one for each button). The end of the remote had a screen covering it. We found that you could use a belt buckle as a remote, but the results were pretty random, but when you want to confuse people that was enough.

CP/M & Z180 - wow lots of work was done

by archer＠topnow.com

I guess the magic search key for Google is CP/M and Z180. Wow, a boatload of stuff. Came across schematics for a P112 board, SB180, others, and BIOS listings for CP/M customized to these boards, and lots of other goodies. Does running 10+ year old software on new homebrew hardware count as "half-classed" (or maybe just half-assed) classic computing? Maybe we need a name. I nominate: Repliputing. :) -- Ross

TK 50 with VMS???

>Isn't the RRD50 the one with the wierd "pincer" caddy? I've found it to be >very bootable and useful. Sure it's *SLOW*, but hey, the important thing is >that it boots! OTOH, if you try and hook it up to something like an >AlphaStation 200 4/233 I know for a fact it won't work. No - the RRD50 is the tabletop device with a pop-up lid. I'm pretty sure it is slower than the (later) RRD40. Both used the KRQ50 Qbus interface, although the RRD40 was also available with an internal converter board that turned it into a SCSI drive. Quite popular in the early VAXstation 3100s, IIRC. I have an RRD40 right in front of me and (again, AFAIK) it can be used as a boot device but unlike the RRD50, it's only dog slow :-) The RRD40 and RRD50 both came from Philips (I think). Both used their LMSI(??) interface. The converter board that helped the RRD40 do SCSI was reputed to be "not that good". Put another way, the RRD40 has a bunch of quirks. I'm not in the least suprised that an AlphaStation turns up its nose at it. (I vaguely remember some alpha console command that can tweak the SCSI interface - perhaps you can persuade the two to get on that way ... assuming you can find the details which I've helpfully forgotten!)

While I would agree with the recommendation to go with a modern OpenVMS variant (V7.3 or V7.2), the VAX 4000-200 was in fact supported as far back as VMS V5.4-2. TF85 support may not go back quite that far: I don't have the old VMS SPDs to hand. Antonio

TK 50 with VMS???

by Antonio.Carlini＠riverstonenet.com

The TF85/TZ85/TK85 are all the same basic drive, with DSSI/SCSI/STI interfaces respectively. Everything up to the TZ87 can read TK50 (CompacTape) and TK70 (CompacTape II) carts. The TZ87N was a cost-reduced TZ87, some of the cost saving coming from dropping the backwards compatibility. Beyond the TZ87N, nothing (AFAIK) can read TK50 or TK70 carts. Antonio

reviving a HP 9000/310

by glenslick＠hotmail.com

Can you stop the boot process when it is searching for a boot device and then manually select the boot device and add the ISL option? If you can get to an ISL prompt then you should be able to boot in single user mode. I have no idea if older HP 9000 systems have an ISL prompt, my experience is limited to 9000/700 series systems. >From: "Rumi Szabolcs" <rumi_ml(a)rtfm.hu> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: reviving a HP 9000/310 >Date: Tue, 27 Aug 2002 01:53:48 +0100 > >Hello! > >I'm currently trying to make an old HP 9000/310 machine work. >Some information about the machine and the status of the >"project" can be found out at: > >http://paranoia.rulez.org/~rumi/hp310.html > >What I currently need is either a way to crack into the >HP-UX that is already installed on the box, or a floppy >set (== images which can be written to floppies) of HP-UX >that would run on this machine which sports a Motorola >68010/10MHz CPU, 2MB RAM, and a HP9153C 40MB HP-IB hard >disk drive / 3.5" floppy drive combo. > >If you have such floppy images, or could help me with any >software, documentation, or information regarding this system, >please don't hesitate to contact me via email. > >If I succeed, I'm planning to put a nice webpage together >about the system, with pics, history, infos, etc. > >Thanks, > >Szabolcs Rumi > >- _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

Conclusion: Commodore 64 *is* lame!

>Worse, I can't get the video to work if I plug the cable into the back of >the 1702. I can only get it to work with the composite connector on the >front. Maybe it's because I still don't have the right cable. Whatever. >This is a nightmare. The rear connectors on that monitor are Y/C connectors, not Color Composite. So unless the cable is dumping out a Y/C signal, it might not work there (although, IIRC, you should still get a B&W image when plugged into one of the two channels... so maybe the rear inputs on that monitor are broken?) I also recall a switch back there for something. I can't verify as I sent my 1702 to Toth along with a complete C64 system (which I have regretted ever since, as it was a very complete system... but I suppose with him it has a better home where it is really being used, as compared to me where it probably would have sat in a box for the rest of time) -chris <http://www.mythtech.net>

MMD-1 / Mini-Micro Designer programming

Karl Bernst writes: > I've got an octal keypad plus the letters "H,L,G,S,R,A,B,C"... Anyone = > who knows exactly what they do? After doing a web search, I found a listing for the keyboard routine. http://www.classiccmp.org/mail-archive/classiccmp/1998-04/0779.html It appears that you enter an 3 digit octal number and then hit a function key. H - puts the number in the H register L - puts the number in the L register S - puts the number into memory pointed to by HL and then increments HL. G - Loads the program counter with the contents of HL I dug out my copy of "the 8080a Bugbook", but it does not discuss the operation of the keyboard.

BACK-OT: which CP/M machine is best (to copy)? :)

by doug_jackson＠citadel.com.au

I vividly remember my Pulsar Electronics Little-Big-Board. It was an STD bus board, sporting a 4Mhz Z-80, 64K ram, 8" floppy disk interface (1.2Mb!!!), RTC, and dual serial ports. The board came with a full BIOS listing, as well as the device specific CP/M stuff. I remember that you could re-link the CP/M innards to allow HDD support (I was never *that* rich). Spent *many* hours on that box, running Wordstar, and a cool pascal compiler called Turbo Pascal. I used a terminal that I brought from the US (ZRT-80). I still have it, in a 19" box, with dual M4854 (5.25" 77 Track) drives. (Boy, it was hard to find the HD media then). The box had the bigest storage on the block, and I was the envy of all my friends when it came out. A mate had an kaypro system that supported dual 170K? disks. (grin) From memory, the board cost about $500 Aus, each drive cost about $450 Aus, and the Apple II power supply for the case cost about $35US from Jameco. All in 1985 currency. Anyway, back onto topic. I still have all of the listings, and the full schematics for the box as well.

Outbound (Mac-compatible) laptops.

by mtapley＠swri.edu

All, got in contact with an old friend of mine, Jeff (no.trag.spam(a)io.com, remove the obvious and the dots before the @), and got some information relevant to the Outbound systems. Here's the useful stuff: >Yes, Outbound. I don't know why so many people write Outback. Maybe >because of the steak house? He goes on to say he has one and some parts, but not any he wants to dispose of right now. >Chris mentions the docking ability to a Mac Plus (could also be a Mac >SE). I don't have that docking adapter. The thingy that goes >inside the Mac Plus. I really want one too, but have not been able >to find one anywhere. I put an ad in the news groups every so often >with no results. ... >I >have taken them apart and done repairs and such so I know them pretty >well. Most of that work was close to ten years ago though, so the >memory may be hazy.

UnixPC 7300 --> 3b2

by MichaelDavidson＠pacbell.net

FWIW the UnixPC 7300 which was belatedly adopted into the 3B family, and renamed "3B1" by the marketing guys, despite having nothing in common with the other 3B machines, was actually a close cousin of the CT Miniframe. (I'm not sure if Convergent actually manufacured the 7300, but it was certainly their design)

MMD-1 / Mini-Micro Designer programming

by karl＠jagegud.com

Hello. I just subscribed to this list because I got my hands on an MMD-1. My teacher in digital tech was going to throw it away but I managed to stop him. He had already gotten rid of the instruction book. My problem is that I've never programmed anything like this before, and I'm having a hard time understanding anything of it. I have read a few threads in this list about the MMD-1, but they didn't help much. Let's say I want to put a number in one of the ports, how do I do that? address data mnemonic comment ------- ----------- -------- -------------------------------------- 004 000 076 123 MVI A<-123 ; load 123 into A 004 002 323 000 OUT 0 ; write it to port 0 004 004 166 HALT (code from http://www.cs.unc.edu/~yakowenk/classiccmp/mmd2/programs/setPorts.html, so it's really for the MMD-2 but I think they are quite alike) Now that would put the octal number 123 in port 0, right? How do I enter this into the MMD-1? I've got an octal keypad plus the letters "H,L,G,S,R,A,B,C"... Anyone who knows exactly what they do? /Karl Bernst?l

Shameless Plug Alert

by kyrrin＠bluefeathertech.com

Hi, gang, Well, I'm back. I may not collect computers much any more (my ham radio and test gear interests have flared, big-time), but I still have some decent stuff to get rid of that I think just might find a good home with some of you. I still come across classic stuff in my travels as well, so I think it's worth it to maintain contact. Here are some links to stuff I currently have listed on Ebay. S-100 system owners should take special note of a couple of the items. ;-) DEC Micro-RSTS 2.1, and various PDP diagnostics and formatters on RX50's: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048901683 MultiBus Extender boards and a MultiBus prototype board: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1761718677 S-100 Bus Extenders and Prototyping Cards, all unused/NOS: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048953253 Wombat QBus-to-SMD disk controller: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048984536 S-100 Bus Passive Backplane Cards (six-slotters): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048994932 Also: I still have available, for local pickup southeast of Seattle, a MicroVAX 3 (KA650, 32MB RAM) in the BA123 (end table) enclosure, priced at $100.00 or best offer. It includes a Sigma RQD11S SCSI/Qbus host adapter that can work either disk or tape drives, two 760MB SCSI disks, TK50, etc. Last time I fired it up a couple of years ago, it was still booting from the NetBSD load I put on the disks. I don't recall if the Sigma adapter will boot from CD-ROM or not, but I'll throw in an RRD40 and its controller if I can find them. Thanks for putting up with a most shameless plug.

I hate to do this, but.. FA Osborne 1

by nerdware＠ctgonline.org

I didn't want to go ebay, but last time I posted here with surplus stuff and asked for offers, I got no response. However, in case you're interested, I have put my Osborne 1 up on ebay. It's an original beige case unit. Monitor lights up, but can't get it to access the drives to boot, which I understand is a common fault amongst surviving Osbornes. The AC cord cover is intact, it's in good cosmetic condition as well, and includes the original disks in the original disk box. The included disks are: CP/M system CP/M Utilities MS Basic Wordstar (includes keyboard overlay) Supercalc. If you want to see it, it's at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2047971573 I'll try offering a bunch of Apple II stuff here on the list in a couple of days.... it's time to get out and concentrate on the things I do have time for.

HP Apollo Series 700 model 705

by hansp＠aconit.org

I have been given a couple of these (thanks Paul) and would like to know more about them. These were obviously used as network stations, neither has a hard disk and from the looks of the inside hard disks were never installed. Both power on and blink the indicator lights on the front but I get nothing on the connected multisynch monitor - is this normal? Any pointer to technical info would be welcome, the HP doc archive does not mention this model. Regards, -- hbp

HP gear

by pat＠purdueriots.com

I've just come across an HP 9000/300 and 9000/220 in a dumpster over here at University Salvage. I see that the 300 has a 68010 (first one I've owned), but am not sure about the 220. Both have video and 'keyboard' connections. I've found some 300 info using google, but nothing helpful on the 220. Also, are these worth anything? I've got no drives with them, but I did get a bunch of lab I/O boxes (multimeter, and other things) with them. -- Pat

Conclusion: Commodore 64 *is* lame!

by foo＠siconic.com

Ok, here's how lame the C64 is. I have three of them. I have three different types of video cable. The first thing I notice is that the C64 I've been working on has a different video connector than the other two. The other two are older; the one I've been working on newer (based on serial numbers and internal differences). The one I've been working on is most likely dead. I can't get anything out of it after trying various combinations of cables and monitors. So how come none of you C64 experts piped up to tell me that the video connector on the C64 changed over time? The later one had more pins, and the C64 video cable (that I searched all over for and finally found) only plugs into the newer style connector. It won't plug into the older ones because there are too many pins. Worse, I can't get the video to work if I plug the cable into the back of the 1702. I can only get it to work with the composite connector on the front. Maybe it's because I still don't have the right cable. Whatever. This is a nightmare. See, this is why I have such a poor opinion of the Commodore 64. Sure, technically it's a nice computer. But practically, it's a pile of shit.
