HP Vectra VL2.
Very sturdy machine, with 4 ISA slots and 486 overdrive compatible.
Mine works perfect for more than 15 years, I use it for the hp language processor board and elv ic-tester.

Onderwerp: Help building a DOS system for ImageDisk
I'm trying to put together a DOS system on which to run the ImageDisk software, as found here:
http://www.classiccmp.org/dunfield/img/index.htm
The ImageDisk documentation recommends at least a 486-class system for best results, although it'll run on an original PC:
"ImageDisk requires a DOS based PC with an AT type floppy
controller. Although ImageDisk will run on a 4.77Mhz PC/XT type
machine, some of the analysis functions are real-time intensive
and best results will be obtained with a 486 class machine or
better."
ImageDisk is naturally finicky about its floppy controller, since it uses modes that are not normally employed for MS-DOS disk formats. After studying the list of controllers known to work well with ImageDisk, I ended up buying an Adaptec AHA-1522A SCSI controller on eBay, because it's built-in floppy disk controller happens to be a good one for this application. It's a 16-bit ISA card.
I thought I already had a computer to plug it in to on my junk pile, but those all turned out to be much too new, with PCI slots only. Thus, I'm looking for some help looking for a machine that I can buy for running ImageDisk on. I don't want to waste space with any old arbitrary no-name clone machine; I'd like to get something that has some collector appeal all by itself, besides its utility for running ImageDisk with that AHA-1522A.
The only PCs I'm familiar with that particularly interest me on their merits would be the original IBM PC and PC-XT. Those seem like they would be under-powered for this application according to the ImageDisk documentation, though.
I hope that somebody who's more familiar with vintage PCs than I am can help me find a machine that meets these goals:
* Must have at least one 16-bit ISA slot to accept the AHA-1522A board.
* Must be able to disable any on-board floppy controller so that the AHA-1522A's floppy controller will not conflict with it.
* Should be "486 class" according to the ImageDisk notes... yeah, I know that's a bit of a nebulous requirement.
* It would be nice if it has an IDE controller so I can use an IDE to CF adapter in place of any hard drive.
* It would be nice if I can use an SVGA LCD monitor that I already have with it.
* It would be nice if I can use the Model M keyboard with PS/2 interface that I already have.
* I really, really, hate orange Compaq displays. :)
* Preferably not too huge.
* Preferably not too expensive, and something I'll be able to find in short order on eBay or from another collector on this list.
* I'd just run DOS on it, and I wouldn't care at all about things like mice, sound, etc.
* Not a no-name clone; something that has some unique collector appeal of its own. This will be hard to satisfy, as I consider the "486 era" to have been an especially boring era of computing. :)
* It'll be helpful if the case is easy to open, since I'd regularly need to plug in various disk drives, even including 8" ones.
Do any of y'all have suggestions?

Madness takes its toll - please have exact change.
The P112 kit has been claimed. I hope to have more available in a couple
weeks.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
With a keyboard that works well enough to get into setup. Ideas using it as a logging terminal, Since they keyboard is missing a few keys, but it's been in my garage too long. I believe it's amber.

Are list messages being actively archived and put online anywhere these
days? I have a shade over 68,000 messages in my classiccmp folder, going
back to 2008, and Thunderbird is about ready to explode.
I need to have a clear-out; can I delete them because they're available
somewhere, or am I better off keeping a snapshot of what I have? I'm sure
other people have offline copies too, but I'm more interested in them being
immediately accessible should I want to refer back to something I know I've
seen in the past. If I remember right, the archives on classiccmp.org
itself have always been a bit patchy.
(Thunderbird question: If it is sane for me to keep them, do I just need
the 'classiccmp' file at ~300MB, or do I also need the 'classiccmp.msf'
file at ~36MB? I'm not sure if the latter's perhaps just an index which
will get regenerated in its absence anyway?)

My insatiable terminal collecting habit has cost me another couple
square feet of space. By way of a well-spotted Craigslist ad, I have
acquired an IBM 3278-5 terminal:
https://picasaweb.google.com/102190732096693814506/IBM3278Terminal
I'll need a terminal controller, so it'll be a long time before this
term sees a mainframe session again. But it does power up and I'd
like to at least test the local mode, so I'll need a keyboard, too.
A few have appeared on eBay recently and sold for much more than I
expected. Apparently there are a lot of 'boardless terminals out
there. Aside from waiting patiently for one to come along cheap, what
are my options here? The keyboard connector is a 25 pin and I believe
it uses a serial protocol. Are there other IBM keyboards that may
work? Any that can be adapted? For terminals, I have a 3178 keyboard
(p/n 6052141) with the 15-pin connector.
I know there is a 3278 -> PS/2 adapter project out there but it was
intended to go the other direction, to use the 3278 keyboard on a PC.
Perhaps it can be adapted to go my way?

PDP guys and girls,
There's a nice looking PDP 11/34 with tape drives, disk drive for any one
close to Menlo, CA on a certain auction site for $300, bet it won't last
long. I'd be telling about my new 11/34 if I in driving range.

I've got an HP 85a that didn't fare well in it's recent travels to me. The
flyback transformer broke away from the video board breaking 4 of the 6/7
leads (this was apparently an early flyback, it had a U shaped threaded rod
secured with nuts & washers on the backside of the video board that broke
at the outside bend). The unit did boot and run before it's trip so its
worth repairing. I've not been able to source the transformer (or the
video board) at anything below just buying a complete machine again.
Anyone got a lead on one or know of a transformer that could be substituted?

Just picked up a HP 9836 sans monitor. After doing a little research on
monitors for these, I've discovered that it ain't quite plug and play.
I've scrounged through the HP Museum site (and google, google, google....)
trying to determine pin outs, sync, anything to determine what might be
substituted. Has anyone been there done that, have a hint what might be a
direction which direction to begin in?
Tom.
