Anyone on this list ever seen a ThinkPad 860, have one, or know where I could buy/trade for one? Swap for a P/390? :) Thanks in advance! -Ben

I saw a dell 2000 (if memory is working) this morning, and know nothing about it other than it's big. Any interest?

Travan TR5 data tape recovery HEADERQIC113

by keithvz＠verizon.net

I'm trying to recover some data stored on an HP SureStore T20 SCSI tape drive on a Travan TR5 tape. The tape is a QIC-3220-MC format. The data was written using either HP's Colorado Backup II software or Yosemite Technologies TapeWare 6.20 SP3B, or even Backup Exec. I believe it was TapeWare. It was done on either a Win98 machine or a Windows 2000 machine. When I pull the header information off the tape, I see this http://pastebin.com/xn837e0w HEADERQIC113 volume name of Disaster Recovery 00001, Arcada Software, INC. vendor. I'm attempting the recovery in linux, using ddrescue on the /dev/nst0 device. The first 660MB is readable but of course the files still need extracted from the raw tape dump. Once an error is encountered, the HP's firmware takes the SCSI device basically off-line, and tries multiple passes, resync's the tape, tries again, and basically goes unresponsive. I'd love to go "raw" and just have the drive report a straight-up error, and move past it on the tape, because there could be more readable data stored later. Even if I'm able to extract a large portion of the data, there's still the issue of how to handle this format. I've found the QIC113 spec online, and it doesn't seem impossible, but obviously it might be nice if there were pre-made tools out there to deal with this. Anyone familiar with any tools that can manipulate this file format? Is it possible to disable the "intelligent" error handling of the drive to just read it in a raw manner? Thanks, Keith

DG Nova 3 Bulb Number?

by nf6x＠nf6x.net

Do any of y'all know the bulb number for the fragile little wire-leaded bulbs used in the Data General Nova's switch console? I have at least one burned out, and a couple have snapped off. I measure about 15V across the bulbs on my machine, but I don't know yet whether that's the correct voltage, nor do I know the nominal voltage, current or brightness ratings of the correct bulbs.

SLT/386 XENIX on boot drive

by brain＠jbrain.com

I am working on bringing up a COMPAQ SLT/386, and the unit has a bad HDD (120MB CONNER). I swapped in a 340MB CONNER from a spare SLT/286 parts machine, and fdisk shows the volume as XENIX. When I try to boot it, it says: NO OS I was going to repartition it and install something else, but I thought I'd consider other options, if any make sense. Don't have XENIX knowledge here...

Any interest in... Micro Channel cards?

by scaron＠umich.edu

Hi all, I'm doing some housekeeping and I seem to have a pile of IBM MCA-bus cards here, but no longer any MCA-bus computers that might take them. If anyone on-list is interested in them please follow up with me and we can work something out. Here's what I got; it's all for PS/2: 3Com Etherlink/MC 10Base2+AUI (qty 3) 3Com Etherlink/MC 10BaseT+AUI (qty 3) IBM SCSI (FRU 15F6551) (qty 1; sorry, no proprietary internal cable) IBM "RAM EXPANSION CARD" (qty 1; 2 out of 4 SIMM slots filled) I'm pretty sure this stuff is all Linux-compatible. The SCSI card and memory card are 32-bit; the NICs are all 16-bit. They probably all work great but obviously no promises with stuff this old. Best, Sean

any "preferred" disk format for CP/M on 8-inch double-density floppy?

by spacewar＠gmail.com

As far as I know there wasn't any "standard" CP/M 8-inch double-density disk format, with many vendors doing their own, incompatible formats, but was there any reason to prefer any one of those formats over any other? If I hack my own BIOS, I can obviously do it however I want, but it seems like it might be nice to be compatible with something. The Quay boot ROM wants track 0 head 0 to contain eight 1KB sectors, but since I'm hacking my own boot ROM anyhow, I'm not necessarily tied to that.

I've been looking for a Sun 1 for over 20 years. According to all of the info I have found (and early experience with Sun 3's when they were "new") it's not uncommon for Sun-2 boards to be in Sun 1's. Sun sold upgrades to their 1's, 2's, 3's which resulted in you finding a previous generation system with newer generation boards (depending on compatibility.. you might just find a CPU board had been upgraded.. maybe I/O cards, etc.). There are MultiBus to VME adapters as well (got some boards mounted that way). It was also common to find some Sun's with upgraded CPUs from the same generation (i.e. a Sun 3/110 board in a Sun 3/140 chassis). So, going from just serial numbers, and/or part numbers, the best I'd say you'd find would be what generation the various components came from. That's where I normally start. Then the job is to see if you have enough parts to reconstruct an "original" of a particular model. For example, I've not found an original Sun 3/110 chassis, but do have a 3/140... which had a 3/110 board in it. A 3/110 was the first Sun I used, and I've been looking for a chassis a long time as well. Parts for the Sun 2 and earlier seem to be few and far between. It took me 8 years to find a front panel for my 2/120. And it wasn't until earlier this year that I got enough spare parts to begin the restoration.... but now I have 2 sets of boards, 2 power supplies, 3 backplanes, etc., where some are known bad. But I expect to end up with some spare parts... I've not decoded all of the part numbers I have to determine where they all originally came from....but if I have Sun 1 spares, we can chat :-) I also have Sun FEH handbook info that goes back to the Sun 1 generation. I can't say I have complete docs on the Sun 1, but given I got these from a long time and fairly early Sun tech, I suspect I have relatively good coverage. In some areas they were obviously updated by "update" docs which throw off page numbers, etc. But they've definitely been useful for me as I work on my older Suns. Earl

HP 2113e I/O

by pdaguytom＠gmail.com

Hello all, Just picked up a HP 1000e series, it came loaded with 640k in memory but not a single I/O card. I've been reading up on what might be a good set up for a terminal and paper tape I/O (to hook an emulator to) but there seems to be a dizzying number of serial and drive boards that I'm a bit lost on it all. Any suggestions as to what might be a good set up to run a terminal and have some way to push programs to it? I've been reading Terry Newton's site and his hp IPL/OS looks very interesting, especially with the USB drive emulator he's put together. Also, any sources for for boards other than eBay? Tom
