I have an Intel MDS that needs special care. As you may have heard, I was
in a car accident at the beginning of last month. The main casualty,
except for the car, was an Intel MDS. I offered it to the Computer
History Museum and was turned down because they don't have anyone who
understands the MDS well enough to attempt to restore it. Please take a
look at photos of the machine[1]. I can't really let this go for free
because I promised its owner that I would sell it, so please offer
something decent. Except for the lid of one chip getting knocked off, the
boards all appear to be intact. The CRT is not cracked and there's no
apparent evidence of it being breached. If the floppy drive is bad, I
have some replacements. The chassis however, is in sorry condition. It's
made of a foamy sort of polymer similar to the stuff used in older Sun
workstations. The impact of the crash cleaved the chassis into two
pieces: the top containing the CRT and floppy drive and the bottom holding
the backplane and cards. No keyboard was present to begin with.
This owner is the same one who had the Nova 4 I offered
here in September.

I was one of the people who evaluated the offer, and restoration was NEVER
discussed.
Anyone who has seen a picture of what you had offered would understand why.
I've seen gear in dumpsters that look better than that MDS.

Hey, where's my cut? Seems to me I sold you a like-new chiclet keyboard
for that baby for a song...

If you find a shell and need a board I've got a nice challenge for ya:
a 2001 mobo that someone started to convert to 64K dynamic RAMS...

The MC68000 only has a 16 bit ALU and longword operations are done in
low/high word sequence. This is why some longword operations take two
more cycles than their equivalent word forms.

At VCFX I was able to get the last major component for my TRS80 setup
(already have the monitor, drives, and expansion interface). I got the
keyboard unit for $20.
Looks like all I'm missing is a real tandy power supply for the Model 1
(yes, I know I can rig something up, but I'm looking for the real mccoy),
and the buffered cable between keyboard and expansion interface.
Anyone have one of those two items and is willing to trade?

Someone please help my friend Peter. He's outside of Detroit and needs
to move some files from a Mac IIsi, onto CD, to use inside a (presumably
modern) version of Windows. Email him directly.

I am having a very hard time translating Mac files that I have on a CD
into a Windows format. I have found a Mac IIsi computer that works well,
but it only receives input from floppies. This may solve much of my
problem, since a lot of my old work was preserved on floppies, but I
still could use an external drive device that would let me import data
>from my CD to my IIsi. If you have any associates in MI who might be
able to sell--or even to lend--me an old external CD drive, I would
appreciate learning a name or two. I am in Ann Arbor, broadly speaking
in the Detroit area.
Has anyone bought disks from http://www.athana.com ?
I'm pretty sure I sent a price quote request in before, but don't
remember hearing anything back. I just sent in another.
What kinds of prices do these guys have?
Anywhere else that has new 32 hard sectored 8" disks for sale?

Nope, the IP12 SIMMS have an ASIC on board to handle (something
semi-undocumented). Looks like the SIMMS are 16-bits wide, too (2 rows
of 9 chips, with 2 of the chips a different capacity). Anyone tooling
up to make an adaptor might as well go ahead and make the SIMMS and
spare the physical install hassles (an adaptor probably wouldn't work
in an Indigo). I have some 2MB IP12 SIMMS that I've been mulling over
the possibility of putting higher capacity chips on, but I don't know
if I have chips to deal with the different-sized ECC/Parity (probably,
making a guess here though) components.
