The cleaning procedure in the laboratory I used to work in for removing
organics from silicon wafers was typically acetone, then isopropanol, then
ethanol, then a deionized water rinse and nitrogen dry. We did use piranha
solution on occasion when it was particularly caked on (like really old

Does anyone have an idea what this keyboard went to? The "here is" key
tells me it's likely a terminal, but the hex key pad is throwing me off.

I guess I'm on a roll, trying to find out what some things are in the
collection. Any idea what this paper tape reader could've been connected
to?

I suspected that I could somehow get some music out of the SimH PDP-8
simulator for a while now, if I could only make it run real time and toggle
a GPIO pin fast enough say, on a Raspberry Pi. That may still be doable in
the future, but I also had a suspicion that I could generate music not in
real
Glad you guys have enjoyed it. I made SimH keep track of elapsed
microseconds based on the instruction, which means I'm no longer having to
use an average instruction time. This has improved the quality by a huge
factor!

Hi Tom,
Have you successfully confirmed the functionality of your second serial
card? Is it an M8650, M8655, or something else? If you can toggle in a
quick serial echo test to confirm it can receive characters, that'd be a
good start. Sounds like it has no trouble sending characters, which is a

I have this hunk of metal and have done nothing with it since I've owned
it, having two Asterisk systems to play with instead.
Is there any interest before I chunk it? I can possibly bring it to VCF MW
if convenient. Otherwise, it's in Alabama for now.
Thanks,

Firstly, my goal: to run MazeWar on something other than a NeXT.
I thought this would be fairly straightforward, starting with getting SunOS
4.1.3 booting with QEMU. Turns out, I've not had much luck. I get different
error messages depending on what machine type I'm emulating. I can start
booting
