QED 993 Processor Board

[marmotking]

The QED 993 is apparently an 11/93 processor board from what I can find. It's quad width. I'm wondering if I could put it in an 11/23+ with the 22-bit backplane?

The QED 993 is a Xlinix FPGA emulation of a PDP-11. It does not appear to be fully compatible with a J-11 processor. For example, it does not appear to have any FP11 instruction support, which is assumed to be present in a J-11. I haven't been able to get RSTS/E 10.1 or 2.11BSD to run on one I have so for me it is not as interesting as I had hoped.

I tested mine in a BA213 chassis. Should also work fine in a BA23 chassis.

Oh, wow. Thanks! You saved me a lot of potential headache...
