Well, Chuck, thanks a bunch, this is very useful and quite difficult code to write from scratch. How does one compile for DOS by the way (I have to admit I am too young to have ever tried), and get a copy of MSC 8.00C. Is the DOS compiler buried in some part of Visual Studio? I have some old versions dating back from Windows 95 time, when it was called Visual Studio 97...

8-E(s) in Illinois

by useddec＠gmail.com

While pulling parts for another list member my workers found another 8-E. I thought I had 2 in the area, but who knows. Anyway, if you are going to Chicago (VCF) I'm almost 3 hours south of there, but I have several list members who plan on stopping by before or after and might be willing to deliver or get it closer for the right price. I had already planned on selling one, so now I actually have 2. Both are 8-E boxes, H724(I think) power supply, a single omnibus backplane, a switch panel, silkscreen, one has white bezel. They do not have :keys, cover (or lid), slides. I can configure the boards to anything within reason, but I suggest you go with the mos board or kit available on the list. Core is getting expensive. Please contact me off list with questions. Thanks, Paul

Slightly OT: XT-IDE

by afahimi＠fahimienterprises.com

Hello All, I've been trying to help a friend of mine get his XT-IDE (DP ver 2 board) up and running to boot a HDD in an IBM 8525. It is a bit difficult since he is across the country but we have made progress. However, we still cannot get the system to boot. The card is recognized by the system, the boot menu comes up. At first we could not get it to find a HDD. However, after a bunch of trial error we were able to get the drive to be recognized. We booted w/ a DOS 6.22 disk, ran fdisk /mbr, and everything seems to have completed but after reboot the HDD will not format. Checking with fdisk shown no partition info at all. The XT-IDE is the only card in the system, booting from floppies is fine with no issues. We also have gotten a 1h error at times. Finally, to rule out the HDD as an issue we tried to boot using the serial connection. The card is seen by the server but when we attempt to boot again we get a 1h error. Config info as follows: ide_xt.bin: v2.0.0B3 (2013-03-02) Full Operating Mode: No IDE Controllers: 1 Power Management: Disabled Device Type: XTIDE r1 Base Address: 300h Control Block: 308h Master & Slave Settings: Block Mode Transfers: Yes CHS Translation: Auto Internal Write Cache: Disabled User Specified CHS/LBA: No Boot Settings: Display Mode: Default Number of Floppy Dr.: Auto Scan for Serial Drives: No Default Boot Drive: 80h The BIOS chip is an amtel http://www.atmel.com/images/doc0270.pdf EEPROM type: 2864 SDP: Enable Page Size: 1 byte EEPROM Address: D000h Generate Checksum byte: Yes At this point I am stumped. Any help is appreciated. Thanks. -Ali

GRiD Compass power supply information

by ian.finder＠gmail.com

Hi folks, I picked up an 1101 GRiDcompass with no power supply. I'd like to attempt a retrofit. Does anyone know what voltages are in play? I'm specifically worried about the EL panel and want to know if the high voltages for it are produced in the PSU itself, or the panel. Any information, or leads on a spare power supply are appreciated. Failing that, I'll start reverse engineering the PSU in my other 1101- they're just a pain to work on. - Ian -- Ian Finder (206) 395-MIPS ian.finder at gmail.com

E-mail Archives Was: Writing 8" floppies with SuperCard Pro

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow > You can find a discussion about it in the archives (well, actually, you > can't). > Which reminds me.. > The archive have never come back to http://www.classiccmp.org/lists.html Ah, which archives are we speaking of? The CCTalk archives? If so, I've been hosting an 'un-official' copy of the archives from March '97 to January '05 here: http://ana-3.lcs.mit.edu/~jnc/cctalk/ and they should be in Google by now. I do have copies here of the archives from February '05 to Oct '14 (partial), which were wiped out in the big list failure last fall (I forget where I got them from), but they are not on-line. I think there was some talk of them coming back at the main site, but if that's not going to happen, I'd be happy to add them to the collection here. The actual conversion from mail archives to web pages (for the '97 to '05 archives) was performed by john_a_s2004 at hotmail.com (thanks, John!), and I don't have the code to do the transmogrification. I had enquired about doing the rest of the archives, but I didn't hear back. If there is significant interest in having them online too, I _could_ write new code to spit out the relevant HTML message and index files. Should I do so? Noel

More DEC boards

by useddec＠gmail.com

Well, here's another update on my never ending/ always changing list of quad and hex boards. These are all M7xxx, and the M8xxx should be done in a week or so. There are a few boards here I will be using myself, But I am planning on selling off about 80% of my DEC equipment. All is located in zip 61853 and most is shipable. There are a lot of boards to go through yet, and this list does not show any PDP8 parts or industrial control, but feel free to inquire. There are still some DEC things I am willing to trade for, but I also collect US, Great Britain, and Canadian and other coins, boy scout items, and from our English members or anyone else who knows what it is, Doulton, mostly Lambeth. Old microscopes, and almost anything Zeiss. Cash always works. Please contact me off list. https://doc-0s-6g-docs.googleusercontent.com/docs/securesc/o60568klv0gtnika…

IMSAI VDP-80 documentation?

by santo.nucifora＠gmail.com

Today I am taking delivery of an IMSAI VDP-80 and am very happy to have found one. This helps fill in my IMSAI collection. While it comes with some disks (and I can deal with restoring the Persci drives), it comes with no documentation. I do want to restore it to working condition. I also have a PCS-80/30 that, I believe, shares some of the cards but not all and have the documentation for that one. Would anyone have any IMSAI VDP-80 documentation they can share? There doesn't appear to be any online; at least in the usual places. Thanks, Santo

Wang PC260 memory fault

by thrashbarg＠kaput.homeunix.org

Hi List, So a good friend of mine recently resurrected his childhood 286 Wang PC260 after I suggested he replace the keyboard controller. In the 14 or so years it's been unused, it has developed a memory fault in one of the conventional memory banks. The memory is soldered to the board so we're looking for anything that might assist in tracking down the dud memory IC. He can get it to boot if the memory size is set to 256kB, so I'm guessing the second 256kB bank is bad. Is there software that exists that can identify individual dead or faulty memory IC's, or at least the corresponding bit(s) which may not be working? According to Dr. Google, this machine was built by Tandy for Wang. Perhaps there's a Tandy diagnostic disk that'll work with it, or better yet a Wang diagnostic disk. (I'm wondering if this question has been asked/answered before too) Cheers, Alexis.
