np. Are you interested in hacking any of xSU drivers?

Yet another obscure 32-bit workstation from 1980s, custom CPU, custom OS, the works...

Wonder if Leo knows all the code is gone.

Errr... actually it's there, I've just checked a copy out.

In the Browse view a lot of the folders are empty, and some aren't.

And it's unclear how to bootstrap a working system. OS seems to be written in Modula-2.

Perhaps authors of this code still remember that...

A kind soul scanned the technical manual for iskr1030 keyboard, this should make it work in MESS (given time) -- https://www.sendspace.com/file/9hoy55

Al K -- perhaps you can publish it (and other docs) on bitsavers?

First step towards emulation of DVK desktop series (uses PDP-11 instruction set architecture) -- its text-only video board. It's designed to be used with a clone of LK201 keyboard so I've tried to plug in an emulated one, but it doesn't seem to send anything to host?

Next step -- the color graphics board, KCGD. Text-only was easy since it uses 8080 and the ususal support chips, but KCGD (and its host system as well) uses an unique microprocessor implementation of pdp-11 ISA. Here's the skeleton displaying fake input from the host:

(Reply to #96768): DVK hardware

As far as i know, there is no working LK-201 implementation in MESS (both 'rainbow.c' and the similar VT-100 driver abort with keyboard related errors during ROM intialization).

Perhaps R.Belmont or Mister Burke (who provided details about the original DEC LK-201) could give some hints?
