Same here, I've a box full of 256K and 1M and a few 4M.

I've got a pair of 68020 VME cards that really could use four 16M
30 pin SIMMs each but I've never even seen any. I wonder how hard
it would be to transplant a more modern DRAM chip onto an old SIMM?

I've been using Will Kranz's TU-58 emulator to do just this sort of thing,
making images of 5 diskpacks that were included in a recent 11/23+ acquisition.
Use a null-modem cable between the second serial port on the CPU (LPS port) and
connect it to your PC's serial port. You might need a 25pin-to-9pin adapter,
but it's just a standard null-modem cable in any case.
On my 11/23+ the LPS port is set for 9600 (which I think was pretty standard),
but I could go to 19.2K with some jumper changes that I haven't got the nerve to
try yet. Your system might already be set to a higher speed. Experiment a
little and you'll figure it out, or physically examine the CPU board.
In any case, using such a slow speed for transfering 5MB or 10MB images
definitely takes a while, but it is also definitely worth doing. You want to
preserve that diskpack image! At 9600 a 5MB disk will take just shy of 2 hours.

Several working Wyse 60 and Wyse 325 terminals are available for the
taking. They are not PC copmpatable. They connect serially to a
UNIX/Linux/AIX/Sun based server. Located just outside Lebanon on the
southeastern side (Iona).

Does anyone have any idea what this IC is?
<http://www.classiccmp.org/hp/Unknown%20IC/Unk%20IC.jpg> This is the second
one that I've found but I haven't been able to find any information on it.
Not even who made it. It's a standard .3" wide 16-pinDIP and it's marked
PX032768 (9003) and it has a small window on one end. Inside the window is
what looks like a tiny tuning fork or something. Any ideas?

Close -- Canton, MA to Oakland, CA. Mapquest calls it 3113 miles, but
we took a couple of short side trips in western MA, so our trip may
just edge out Vinces's Beaverton, OR to Gloucester, MA roundtrip.
Besides, we had a 28' truck, not a poofy little van :)
(And, hmm, Key West, FL to Blaine, WA seems to be the longest driving
distance in the contiguous 48 states, over 3600 miles. Are any longer
shortest-path trips possible entirely within one country? Looks like
Canada, Russia and China have longer ones, and maybe Chile).
The major geek factor during the drive was maintaining a spreadsheet
that calculated our arrival time in Salt Lake City, factoring in
waypoint distances, driving speed, rest stops and sleep times, which
we used to ensure we'd make it to the Red Iguana restaurant for
dinner before it closed. It turned out we were only allowed three
hours of sleep in Nebraska, but it worked. Left MA on Thursday
evening, and made it to SLC on Sunday night with two hours to spare.
(Why? Seven reasons: mole coloradito, mole amarillo, mole negro, mole
poblano, mole pipian, mole verde, and mole de almendras -- worth a
trip to Utah just to eat there, but this drifting off topic, isn't
it.). Made it home to Oakland Monday night.
> When do we get to see the pictures?!
We should have some pictures of the Sunshine Biscuit Factory remodel
and the system up on ibm1130.org or maybe another site (as we have
everything but the 1130 there) sometime soon; we'll make an
announcement when it happens.

Hi Joe
I think that is a clock chip. It is for low frequency,
like 32KHz.
I think I've seen these someplace but don't recall where.
Why it has a window I don't know but it might be for
laser fine tuning.
