URGENT: Computers & parts needing home - New Haven CT

by woyciesjes＠sbcglobal.net

It's moving time, and for various reasons I need to get rid of a few items: DEC Multia 166 MHz Alpha workstation, not sure what CPU. Apple PowerBook150c Cardinal 386 computer. All in one case, like a Mac SE/30 2 external CD drives, SCSI, with carts various 72 pin SIMMS, some parity, some other 30 pin SIMMS 2 PS/2 keyboards various cables. First come, first served; take it all in one shot, it's free. If you feel this pile is worth something, I won't turn down cash or good beer. If you want to disperse the items to others, that is your choice. If you do make a profit, great! Enjoy it. I just need this stuff to disappear by Thursday, Nov. 13. I tried to give some of these things away before, but the recipient never got back to me about something. Let me know ASAP. Thanks very much -- --- Dave Woyciesjes --- ICQ# 905818 --- AIM - woyciesjes "From there to here, From here to there, Funny things are everywhere." --- Dr. Seuss

Systems based on Fairchild 9440 / 9445

by tshoppa＠wmata.com

Chuck asks: > Anyone remember the > Fairchild F8? Around the same time as the 9440, the F8 was hugely > popular in embedded type applications. Mostek's 3870, a derivative of the F8, was popular throughout all sorts of mass-produced products in the late 70's and through the 80's. STMicro had a chip that was very similar (clone? derivative?) of the 3870 that appeared in consumer products in the 90's. General Instruments certainly took a very similar microcontroller (now known as the PIC) and built it up and out in several directions. Tim.

Systems based on Fairchild 9440 / 9445

by kahrs＠caip.rutgers.edu

As I recall, the 944x series did away with the high order indirect bit just as the Xerox Alto did, thereby permitting full 16 bit addresses. I wonder what became of my data sheet...

Fairchild 944x

I was trying to get the attention of the Fairchild sales department around 1978. You'd have thought with DG not selling the MicroNova CPU to outside customers and the 9440 being a Nova-like chip that Fairchild could have cleaned up. There weren't many other 16-bit chips at the time (e.g. NS PACE, GI CP1600, TI TMS9900). But Fairchild seemed not to be interested in selling the stuff. My understanding is that the 9440 is an "almost" Nova in that it lacks certain features needed to run Nova software. Can anyone verify this? Cheers, Chuck

PDP-8/e and terminals in West Sussex, UK

by paul＠frixxon.co.uk

Thanks to Martin for grabbing 14 DEC terminals from me last week -- very pleasant to meet someone who is still working with PDPs and real terminals in the wild! I've just passed our waste electrical skip at work and noticed that someone has dumped a PDP-8/e box in there. I'm being imprecise about this because I've never seen one before. This isn't a big rack, just a single heavy box fronted by an orange and brown PDP-8/e front panel. I assume it's the processor itself. If I can chuck this in my car this evening, would anyone here be able to pick it up from me by the end of this month? And here's a reminder that I still have a bunch of terminals left; see my previous email for details. The later DEC ones have gone but there are at least 20 Wyse WY-420 terminals available, which have (I believe) a competent VT320 emulation. These are for pickup only from here in Crawley, West Sussex.

Oh man, I am really interested but I really wish I didn't live in Western Canada ;_; If I knew someone close to you I would ask them to pick it up for me and then ship it in chunks but even then it would still be expensive.

OmniProm programmer

by jeffj＠panix.com

I'm trying to revive an EPROM programmer: the bottom label says Omni-Prom Programmer model OMNI-01 SherTek, Inc. Memphis, TN USA but the inner label says P/N OMNI05, V7.0, R0.0 (C) 1986, SherTek Inc. It has 28, 40 pin ZIF sockets on top, internal power supply. But the only interface is for the PC's parallel port so I'm unsure what protocol it uses to read back the results. I'm missing the floppy with OMNI.EXE the DOS program that ran it. The manual only documents the program menu, not the parallel port protocol. Any clues? -- jeffj at panix.com

UK source of small UNC nuts and bolts?

by ard＠p850ug1.demon.co.uk

This is classiccmp-related in that I am repairing an old HP 'Multiprogrammer' (a modular input/output system for HP2100s, HPIB machines, etc). While dismantling it I had one screw shear off and had to drill out pop-rivets holding a heatsink to the side casting. So waht I am looking for is a source of small UNC nuts and bolts in reasonable quantites. 'Small' means 4-40, 6-32 and 8-32. I would be looking for countersunk and pan head scewws, nuts, lockwashers, etc. 'Reasonable quantities' would be a bag of 100. These are not at all common in the UK, we tend to use BA (older machines) or metric (M3/M4 sizes). Does anyone know a company who can sypply these to the UK? Preferably one based in the UK (to save on postage charges), but there's no real problem with shipping a ag of nuts and bolts from anywhere. -tony

Monroe OC 8820 - OS8MT

by leaknoil＠comcast.net

I just picked up one of these old CP/M boxes but, I've been unable to locate any software for it or documentation. They ran a custom version of CP/M called OS8MT and came with a few different software packages. They were made around 1984 I think. Old-computers.com has a little bit about it if it helps ring any bells. http://www.old-computers.com/museum/computer.asp?st=1&c=1078 If anyone knows of a source for any of these disks or docs I would love to know about it. The system is in excellent shape and the monitor clear and sharp. Really a shame for it to not be able to do anything but, hold my doors open. Thanks

Memory test util for classic macs?

by mc＠media.mit.edu

Josh, If you can't boot the OS, you'd be hard-pressed to run a memory test. As you already suspect, that error strongly suggests a hardware error. Assuming the memory is not soldered to the motherboard, the first thing I would do is to re-seat the memory. If that doesn't work, I'd try removing some of it, and try different combinations of memory cards to see if some subset works. Usually memory from that era needs to be added and removed in pairs, and needs to positioned in the right slots. --Tim On Nov 1, 2008, at 5:09 AM, cctalk-request at classiccmp.org wrote: > Message: 26 > Date: Fri, 31 Oct 2008 17:24:54 -0400 > From: "Joshua Alexander Dersch" <derschjo at msu.edu> > Subject: Memory test util for classic macs? > To: cctalk at classiccmp.org > Message-ID: <E1Kw1UE-0002Q9-LD at sys27.mail.msu.edu> > Content-Type: text/plain; format=flowed; charset="utf-8" > > Anyone know of a decent memory test utility that runs on classic > macs (68k > based)? > > I have an old Mac Portable that I'm struggling to get an OS on -- I > consistently get "bad F-line instruction" traps when booting from > System 7 > disks (floppies and CD-ROMs), which from what I can tell probably > means bad > memory.

Looking for a ST419

by jeff.kaneko＠juno.com

Geez, the 419 was uncommon, even in it's own time. And then, most of the ones I saw didn't work. If you don't mind 'wasting' part of the drive, I would think just about any 6-headed mfm drive would work. There's some difference (which I have been unable to quantify) between different models of MFM drives (of equal or similar geometry) that allows some drives to work in some applications, but not others. If there's anyone out there intimately familiar with the ST-506/412 interface, now would be a good time to offer some suggestions as to why this is so. -- Jos Dreesen / Marian Capel <jos.mar at bluewin.ch> wrote: I am in the market for a known working ST419 MFM disk System software forces me to the 306 Cyl / 6 Heads format (@ 32 256-byte sectors ) Location : Switzerland .

Zilog System 8000

> From: Oliver Lehmann <lehmann at ans-netz.de> > Subject: Re: Zilog System 8000 > So - none has a S8000... at home? ;) The MARCH computer museum at New Jersey's Infoage has a Zilog Z8000 model 21. http://www.infoage.org http://midatlanticretro.org/ Sadly, I scrapped my model 21 and 31 when Linux overtook Unix as the preferred software developer's platform. I still have some pieces (SMD hard drive) but I gave away some of the main boards to someone claiming to want them for the CPUs. I'm unsure how to get it running from bare boards because I suspect the backplane was not just parallel connectors. All the slots were specific to the CPU, RAM, disk controller, serial ports, tape drive, etc. How I wish I had photos of the Exxon Office Systems office in New York's Rockefeller center in 1982 when they were selling the Zilog System 8000 running the Zeus OS as servers to Z80 systems running Z-net (their proprietory coax network). Only a few years later at the NJ Trenton Computer Fest, a fellow was selling a pair from the back of a red pickup truck.

I suspect you'll need the front panel with the reset and interrupt buttons (and a few LEDs) to invoke the ROM monitor. Or at least know where they connect.

It is lost in my container. I saved the hard drive since I was hoping to use it on another system, failing to predict the amazing velocity of new technology becoming available to everyone.

Memory test util for classic macs?

by derschjo＠msu.edu

Anyone know of a decent memory test utility that runs on classic macs (68k based)? I have an old Mac Portable that I'm struggling to get an OS on -- I consistently get "bad F-line instruction" traps when booting from System 7 disks (floppies and CD-ROMs), which from what I can tell probably means bad memory. I'd like to find out if it IS memory, and if so, whether it's the onboard 1mb (I hope not) or on the 4mb expansion... My internet searches have come up dry (I've found stuff for OS X, and early PowerMacs, but nothing for the 68k line). Thanks, Josh

HP9133D disk replacement.

by jeff.kaneko＠juno.com

Yah, I done that. The key is to find an MFM drive that has the same or greater Cylnder/Head geometry: It has to have at least the same number of cylnders, and at least the same number of heads. Keep in mind, though, that geometry alone does *NOT* guarantee that this will work!! The 9133 seems to be allergic to some MFM drives-- I could get most Seagate drives to work, for example, but not NEC's. My fave at the time was the Quantum Q540. I 'wasted' over half the drive, but I had alot of them at the time! When you format such a drive, you will not have a capacity greater than the original.[1] [1] Not quite true for the older 9133 V/X/XV drives. If you have a 'V' for example, you can replace it with a bigger drive, adjust the jumpers inside, and format for 10 or 15MB. -- Jos Dreesen / Marian Capel <jos.mar at bluewin.ch> wrote: Closely related to the previous post : I actually have an ST419, but is in use inside a HP9133D. Looking back to old classiccmp articles indicate that it is not easy to replace the ST419 by other MFM drives of different geometries. Has this changed ? i.e can somebody report a success in replacing the internal drive of an HP9133 ?
