Re: QED 933 (11/93 clone) and mystery SCSI board

[Rico Pajarola via cctalk]

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.

Is there any documentation anywhere? Bitsavers had only a thing on the QED-95.

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.

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

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 10006050-6005-B(Systems Industry?) quad
height .

Does anyone have any info or interest in these?

Thanks, Paul
