Yes, I'm interested. I also have a broken LK201, and I have a Trinket
lying around.

Does anyone have, or know of low level documentation for Evans &
Sutherland Picture System 2 hardware?
I walk past a PS-2 monitor all the time and some of us started talking
about bringing it back to life. I'm not sure if more of the system
exists, but it might. I plan to check.
I looked o

Sorry, I can't help. Is there any software for it?
I do consider making an emulator for the E&S LDS-1.
I have one, but no documentation I'm afraid. The last time I turned it on was
20 years ago. The last thing I remember is the fuse in the display blowing. I
ordered replacements, but never got it going again.
They take a lot of power, where mine is currently sitting I don't have the

I would absolutely be interested in this - while I'd love to use original
hardware where possible, it's not always easy to get peripherals at the same
time as machines. A long term dream of mine is to build some sort of
general-purpose box that can make connections to arbitrary vintage computer
Do you guys want original LK201s, or other keyboards that LOOK like LK201s
in the caps and layout, or converters?
I am a little confused... LK201 clones do not have the clip offset on the
terminal connector, so you would have to replace the connector. I have no
idea if the protocol, voltage, etc

Readymade cables exist to allow Wyse and other terminal keyboards to work on
USB. Would a reverse of this work?

Interesting starting point, but I tried to browse the code and it
flashed up instructions for how to use cvs or rsync to pull the code
down
Lets have another go (but this time I have some pictures)
Decstation 5000/125 – also houses a CD drive.
Two expansion storage boxes – one has a tape drive and the other one has
a floppy drive.
Two very large and heavy RGB Digital monitors – one has both Digital and

Tai-Ho (Taiwan) was the OEM supplier for flyback transformers used by Apple in
the early Macintosh computers (1984+).
Russell Industries (New York, USA) produced replacement flyback transformers
for monitors and TVs, these appear on eBay and remaining TV repair supply
houses.
