Re: QED 933 (11/93 clone) and mystery SCSI board
I bought one on ebay a while ago, but I didn't have a QBus enclosure to try it. I finally got an enclosure at VCF west, and I'll give it a try as soon as said enclosure has made the trip home. I never found any information on it except that it is a "compatibility challenged FPGA based 11/93 clone without FPU". If anyone has a manual, that would be great.

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.

They re not quite the same as the DEC one.
