Depends on who you're talking to... :-) There are 3 factors to consider in using non-DEC boards these days, I find. #1 - Can you get documentation? (In this case, yes. I have some where the answer is a resounding no, e.g. a Clearpoint DCME/Q4E 4MB PMI memory card.) #2 - Can you get the cables/etc? I don't know the answer in this case; I will note that this apparently doe not use the same cable as a DLV11-J - it uses a 40-pin header - _but_ you may be able to plug your DLV11-J cable into it. There's an page that talks about it a bit: http://www.avitech.com.au/pdp-11-03/ba11nc.html#SCD-DLV11J/8P although note that there seems to be something wrong with the URL for the image of the board on that page, this works: http://www.avitech.com.au/pdp-11-03/pictures/SCD-DLV11J-8P_640X480.jpg and according to that page, you can plug a 10-pin shell into the 40-pin header. Seems slightly dubious to me, but maybe it'd work! #3 - How good were the boards when they were new? Reliable, flaky, etc? In this case, Sigma mostly made pretty good stuff, although I have no experience with this particular card. Your call! Noel
