Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X
(175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production.
I'm fond of it, but probably more for the fact that it comes in a rackmount
sled, which appears to be quite rare. It fits nice at the co-hosting
facility (it's www.thistle.com, but it doesn't talk to anyone but me right
now).
What I know:
Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM
slots, but it will only accept 8MB, true parity, generic SIMMs (giving
64MB). And it's damn finicky about those. My 3000s spits on SIMMs that
everything else in the basement has no trouble with. It will also accept
Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that
I've found will work, but that could just be me. If anyone has any of these
SIMMs they don't want, do let me know...
Video: AFAIK, none of the free *nix systems support the built in TC frame
buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and
display to another machine. Real men do serial consoles anyway.
Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one
of my PPro 200s for (other than the swanky rack-mount sled). Definately
useful for low volume web, mail, etc., but "make build" isn't pleasant. My
PC64-275 is way, way faster, but still not that fast.
There's lot's of good info out there, and I know there are people working to
support all that isn't currently supported. Drop me a note if anyone wants
to know anything else.

How about Earth-Moon-Earth? Or data-encoded chromosomal strings? Hmm, or
fragrances (data stored in the molecules of a volatile chemical)?
Or --
Data encoded in the hand gestures of a person depicted in a video tape made
available to the world.
Networking, indeed.

I was going to ask about that, but I didn't want to "make any
waves". :)

Correct.

I hope your eyes are better than mine -- these friggin things are *tiny.*

The stringy floppy is flawed the same way an 8-track audio tape is -- it
only moves in one direction. As a result, A&J didn't write any OS for
their drives, just a couple of simple commands. You search for the file
you want, and you either find it (after several minutes) or you don't
(after several minutes).

Nope.

Ahh, neat! I've heard a bit about Wang VS systems, but I had no
idea they were TTL CPUs. Very cool. How wide is the processor? The
74LS181 is 4 bits wide...how many does it use?
Have you had a chance to take pics of this system? I'd be highly
interested in seeing them if so.

Cyrix made a 586 m1sc which was their 586 pentium clone
modified for use in a 486 motherboard, its the fast cpu
for 486 motherboards.

MicroTest is still around.. They sold off their NAS stuff, but a quick search
for
for 'NAS Microtest GPL violation' tells me the new company is xStore at
http://www.xstoreonline.com

This pass Saturday was a long drive MN to IL (12 hours total drive time)
to pick up 2- Cromemco System Three's, a Systemv CS-300, one new in the
box KB for these systems, lots of manuals and software for them, a
Cipher 1600BPI tape unit, a model BRZ-III fan for the units, and some
parts. All will have to be cleaned up as they are pretty dirty and need
some loving care. The guy had over 1600sq feet of computer stuff he is
selling most on eBay.:-( At a local thrift I got some Sega master
stuff, like the 3D glasses that have been selling on eBay for $50, I got
mine for a couple dollars. Got a Virtual Boy system for $11.99. Got
some Atari 2600 stuff also they were selling cartridges for 80 cents and
they had two big boxes full. Now I will start the clean-up and entering
all the info into the database (my paper notebooks). Keep computing John

Correct, RCA data book lists as CD4063B CMOS 4-Bit Magitude Comparator

Here's the pinout:
