I'm sorry. I didn't mean to imply that you were wrong, just that I was.

Never looked carefully at RQDX?, but the DELQA uses an M68K, that much I
*do* know. (As do the DELUA)

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...

> The DEUNA is quite different.

Obviously. But it is also pretty old. Not as buggy though, which should
have been a clue. :-)
