Are these all derivatives of the 3274 and its protocol?
What were the various "IRMA" cards?
I have some protocol docs in the 3274 FE manuals.
Anyone have interest in an IBM 3363 drive? I've seen a couple
on e-bay that didn't sell.
I have one, with 2 PS/2 controllers, and a couple of blank media.
I don't (and never have had) a functional PS/2 machine to plug it
into. Status is unknown (as I have no way to test it), in original
box with original manuals/driver disks/etc.
What is it's value, anyone want it for reasonable value/shipping
costs?
Anyone have a few drives to sell/swap?
I'm restoring a few old systems and have come up short!
I could use:
1 or 2 5.25" full height DSDD drives
1 or 2 5.25" full height SSDD drives
a single Shugart 801R
a few extra 50 wire cables for 8" floppy drives

Hi William,
I have a Documation M300 and M600, Both might say DEC CR11. Also some
Decitek paper tape readers that seem to be RS232. Might be able to scrape up a
PC05. I know where there were some IBM 026s, but not sure if they are still there.
And a few tons of DEC stuff.
Thanks, Paul
Just bought a Compudyne 386 desktop at the thrift store and need help opening the all plastic case. The case has two latches at the top rear corners of the case and a case screw in between the latches. Spring the latches and remove the screw and the top back part of the case comes loose, but it binds in the middle to front of the case and won't remove. Any ideas?
Thanks,
Steve Phipps

I have a copy of the manual on its way to me,
(thanks Jack!) but in the mean-time does anyone
have a PDF of the Altair 88-DCDD floppy disk
manual? In particular, I'm looking for the
section regarding data encoding - format of the
data on the disk itself. Probably some form
of FM, but with hard-sectors.
I've looked everywhere, but for some reason,
most Altair doc sites don't have the DCDD scan.
Yup, the Altair is the next target for the SVD.

Looking for a nice working Compaq Portable 3 (the model with the flat plasma display). Included system disks and manuals would be a plus. Would like to use it to run DOS emulators and do file / disk transfers to my other old machines. Might consider other "luggable" models with 5.25" drives if the price is right. If you have one available, please E-mail me off list at kawninja at cableone.net with price and shipping cost to my zip 64801.
Thank you,

If you haven't seen this yet, there is an amazing
lot of unit record equipment up on ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8792244955
It should go to a museum. (The Computer History Museum has all of
these items already but someone else...) Heck, it IS a museum.
The 2821 controller is a particularly useful if you want to hook up
the 2540 card read/punch and a 1403 printer to your parallel channel
mainframe :)
The seller has some other mainframe gear up. All of the prices
at least 5 times too high, but maybe will be negotiable after the
lots close without a bid?
If anyone is interested in a part of this, perhaps we could put
together some group proposition. I'd be willing to discuss it anyway.
Write off-list if interested
Brian
