<I'm sorry. I didn't mean to imply that you were wrong, just that I was. Not an argument, just posting to the group what went private by error. <Never looked carefully at RQDX?, but the DELQA uses an M68K, that much I <*do* know. (As do the DELUA) Having two Qbus VAXen and several Qbus PDP-11s it's old turf. Also I worked for DEC Engineering. that and I've done a lot of hardware level work on my systems (repaired dead boards) so the designs are more familair. <You obviously knows more about this than I do. :-) <However, as I said, atleast the DELQA have an M68K... <And the DEQNA is old, yes... DELQA is not 68k, The DEUNA is. The DELQA is a cost reduced version (less buggy too) of the DEQNA and is largely logically the same as the DEQNA. <> The DEUNA is quite different. < <Obviously.

The board was far to small for that and had to be Qbus dual width and compatable with DEQNA. I have a few of them in my vaxen too. The Unibus versions DEUNA and the later DELUA were 68k and very good. They were partly the reason why 730s and 750s were used for routers long after they were replaced for other tasks.
