I just found a QED 933. I've had Memtec boards before, but I don't remember
anything about this one.
The other board is a SI-QS 1000 6050-6005-B (Systems Industry?) quad
height .
Does anyone have any info or interest in these?
Thanks, Paul

They re not quite the same as the DEC one. If you get into the on board firmware you will

A few people bought QED-993 boards from eBay in the last few years.
For example 200688358479 or
200600166676. They are set up to use the standard 11/93 console panel,
although only 4 async ports are implemented, not 8.
While they may be faster than a real J11 CPU based board, they have
compatibility issues. The main issue is complete lack of floating
point support. I was unable to get either 2.11BSD or RSTS/E 10.1 to
run on a QED-993. Trying to build the 2.11BSD kernel without using
floating point instructions didn't help.
Maybe it is fast for running RT-11. I lost interest and never bothered
giving that a try.
