Wanted: Processor Technology GPM card...

by wh.sudbrink＠verizon.net

Reposting due to the resounding lack of response and the possibility that something went wrong with the list right after I posted the original... I can buy or trade but I would prefer to trade. I have a large collection of S-100 cards and some other goodies to work a trade with. If it has the CUTTER ROM, all the better. If not, I can burn a 2708 (and I'll probably post a "Wanted: CUTTER ROM dump" message). Thanks, Bill Sudbrink PS... To engender some discussion, does anyone on the list have an operating Processor Technology Subsystem B machine?

Tektronix 4225 -- is it an X terminal?

> All this makes me realise just how much Tek knowledge seems to be a lost - I > mean, the earlier Tek terminals seem to be pretty well understood, but then > most of the hardware, software and docs from the later years has just vanished. It would be nice to try to get this documentation and software archived, if it can still be found. There were a couple of generations of workstations, including the obscure AI workstation that supported Lisp and Smalltalk. A friend of mine worked on the 32000 based system before moving down to the valley. The development systems that had their own OS, then a port of Unix called Tnix. And, all the DC300 based 405x software..

8088 vs. 80c88

by steven.alan.canning＠verizon.net

Intel does some squirrelly crap but I can assure you that unless it says 80C88 it is NMOS ( the -2 version of the 8088 is Enhanced NMOS or HMOS, but still not CMOS ). CMOS is not necessarily slow either, but at higher frequencies it looses it's low power advantage. We used SOS ( Silicon On Sapphire ) 1802s on spacecraft because of the low power, and the SOS makes it much less static sensitive and Radiation Hardened. Intel screwed us when they stepped the 8031 to CMOS ( 80C31 ) as they forgot to mention the multiple pages of errata of things that didn't work right, like Power on Reset and Interrupts.....

Saving TU-58 Tapes

by jhfinedp3k＠compsys.to

I just received a number of TU-58 tapes. Most seem to have VAX software. Is a list of the contents of such tapes available somewhere? I want to save the files before I use them for RT-11. I have seen such a collection of VAX software before and I presume that I am not the only person to save the files. So if this has already been done, it will not be necessary to repeat the exercise. I attempted to look at bitsavers, but there does not seem to be anything much there in the way of software for the VAX. I assume that since there are hobby licenses for the VAX that all of the software is also available. By the way, the dates on the files are 1983 to 1985. Some of the contents are: VAX/VMS 3.4 FORTRAN C PASCAL Are these tapes useful? How are the files saved? Can the files be easily saved using RT-11? What is the best media to save the files? Probably the only reasonable method with RT-11 is to save all 512 blocks of the TU-58 tape as an image so that a VAX/VMS system can easily ATTACH the file as a TU-58 tape drive under SIMH. Sincerely yours, Jerome Fine

Altos 8000-2 booting, SD> DD (CPM)

by g-wright＠att.net

as long as I'm on the Altos thread. I'm trying to make some disks for another list member for the 8000-8200 Z-80 based machines. Both of my systems have floppy disk boot or write problems. So I decided to look into the easier machine which it a 8000-2. basic Z-80 , 1791 FDC and 2, 8" SSDD floppies. The machine will boot a single density CPM disk, read and format a SD disk, but dies if a DD disk is either inserted for boot or the format program on the SD disk is told to format a DD disk. These all have SD Boot tracks, then have to switch to DD, if formated in DD. I have the wiring diagrams and there is a "EN DD" coming off the PIO chip and goes to the 1791 chip, that never changes state. I would believe it would have a floppy density code on the 1st track to tell the OS what the remaining tracks are ??? (just a guess) I know the disks are OK, they can be read in another machine. ( just not copied.). i have looked at the data lines on the PIO chip and have replaced it just in case. I have scoped the started up circuit which also has the "EN DD" tied to it. (input) The software can only be copied by another Altos due to the disk layout. The boot ROM could be damaged?? but not knowing what it should read, its hard to guess. Can't be much there just a 2708. Anyone have a 8200-2 that can read the ROM on, or any ideas. The manual is on Bitsavers under Altos, ACS8000 users manual. The motherboard is a 8100 series (double density) Has 8000 SD, 8100 DD and 8200 in the manual. - jerry Jerry Wright g-wright at att.net

Altos & M/PM manuals available

by silent700＠gmail.com

I have a large box of Altos materials here that I would like to find a home for. About half of it is standard bound books, which will go first. The remainder is ringbound and I am going to attempt to scan them. In addition to manuals there is a lot of dealer sales material, including about a dozen issues of the monthly sales newsletter "ALTOgether." The first lot includes manuals for the Altos 486 (which was really an 80186,) Altos 586/986, Altos XENIX, and a few for the M/PM-II and MPM-86 operating systems. A couple books are a bit warped from sitting in a box too long, but they're all in pretty good shape otherwise. All in all about 16lbs of books. Free for the cost of shipping (Media Mail rate shouldn't be too bad) from 60074. -j

Tektronix 4225 -- is it an X terminal?

by legalize＠xmission.com

See ebay item # 360132413754 That listing just includes the base unit, but thankfully has closeup pictures of the connectors on the back. It looks like it takes AUI ethernet or RS-232 and outputs RGB video. Anyone familiar with these puppies?

Any have a CMD CQD-200/M manual?

by toby＠coreware.co.uk

Hi, Has anyone by change got a manual for a CQD-200/M (QBUS SCSI controller). The device is pretty similar to the CQD-220/M, which has a pdf on bitsavers, but jumpers are alas not the same and I just want to check I've got everything set correctly and enable its bootstrap I've fired it up on my PDP-11/23+ with an RZ27 disk and I can indeed access it via RT-11 but I only get a 32MB (65K blocks) disk after an initialize. Does RT-11 have a 65K block limit on a disk? Thanks, Toby -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Source for 12.44Mhz crystals?

by derschjo＠mail.msu.edu

Hey all -- While I'm waiting for other parts to arrive for my Tek project... anyone know where to find 12.44Mhz crystals? I acquired an old SSM VB1B video card (with an amazing 64 cols by 16 rows display capability!) that was only mostly-assembled, and the crystal is missing. According to the manual (http://www.classiccmp.org/dunfield/s100c/ssm/vb1b.pdf), it's a 12.44 Mhz part but I can't for the life of me find one anywhere -- even my Google searches mostly return links to the VB1B manual :). (And while we're at it -- my Tek project needs a pair of 39M-ohm resistors... anyone know where to find _these_? I know I can hack one up by putting a few others in series, but it's quite a mess...) Thanks, Josh

Datasheet for ICT 27CX321 EPROM?

by ian_primus＠yahoo.com

I've got a handfull of these things that I've been trying to use. My programmer supports them, and I was hoping that they would have the same pinout as a 2732. At the moment, I'm not so sure. So far, I've had three of these chips in the eraser for a good 45 minutes total. If I set the programmer to the ICT 27CX321, it won't blank check - although reading it in and examining the data produces something composed mostly FF's - though not entirely. If I set the programmer to a generic 2732, it passes blank check. I haven't tried programming one yet - although I suppose I could try to fill one with zeroes. So, I take it that these things have a different pinout? I can't find any data on these. Any help would be appreciated. -Ian

A picture of a keyboard or the connections on the back of a terminal would confirm my guess. Tim.

Nicolet 660

by aek＠bitsavers.org

> test equipment seems to be a poorly covered area in the museum > and archive world. I was thinking about this some more last night, and there is little activity preserving the software for test equipment. Brokers keep the manuals and the hardware, but rarely keep the software to make it work. For example, the Biomation CLAS 9000 logic analyzer had no built in user interface; it was a SCSI periperial connected to a Macintosh. They didn't document the protocol to talk to it, so it is a rather large boat anchor without a Mac and the software to talk to it. Then, there are all the PC instruments that had custom cards and software to talk to their widget. The parts are separated, and no one saves the card inside the PC or the software to make it work.
