This will be a long shot...
Do any of y'all happen to have PDF documentation for a Digital Equipment Corp. DECpos2 computer, model MT100-AA? This was a small Pentium PC made for point of sale applications. I found documentation online for an older 386SX based DECpos system, but nothing for the newer DECpos2 yet.
Yes, this is related to Other Stuff I've been asking about here recently. ;) In particular, I want to find out whether its onboard floppy controller can be disabled. The 386SX-based version does appear to have that option in its BIOS settings, according to the user/installation manual I found.

I'm trying to remember how to get a OpenVMS/VAX Hobbyist license. I have
the media. I have an account number for Encompass US, I just don't remember
where to get the license.

Here is a thread on my site about my Pentium III system dedicated to imaging
disks, plus a link to the class notes from the talk at the VCF East last
spring:
http://vintagecomputer.net/browse_thread.cfm?id=561
I am using a generic Pentium III, which will handle the Adaptec card you
have in place of the Catweasel I have.The drive controller of the Pentium
III has no issues with a 5 1/4" HD drive, which with an adapter can mimic a
77 track 8" drive. Note that I have a dual boot system, Dos 6 and Windows
2000. Works perfectly. Very little I can't image with this that is
image-able. I also intend to put in a Quad Density drive, but I have not
gotten around to it yet. The quad density I believe will look to the
Pentium Bios as a 720 3.5" drive.
In short, make your life easy, use a Pentium III with a compatible BIOS.

Hi guys,
I'm a long time lurker but this is my first to the list, If anyone
still running OS X on PowerPC Macintoshes is interested, I've started
building packages on Tiger 10.4.11 using pkgsrc & publishing them for
others to use.
I've written up a brief post on how to get started at
http://www.geeklan.co.uk/?p=1579 if you've not used pkgsrc before.
Packages are currently published at http://sevan.mit.edu/packages
Let me know if you experience any issues, the aim of this exercise is
to get familiar with building software & through that improve support
for Darwin in pkgsrc.
The number of published packages is growing (slowly), if there's
something you specifically need, it'll show up eventually as the
pkgsrc tree is built but feel free to email me off list if you'd like
to add something to build list beforehand.

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?

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.
