The most common "upgrade" was to replace
this card with a two card set of
the 11/03 (M7270?) and the M8044-Dx 64KB card.
Yes it was or in a later time frame m8186 (kdf11, 11/23) with m8044s. that
workes better than 11/23+ (m8189) as it was a dual solution and the hath
backplane was rather cramped.
know that I was unsuccessful getting anything other
than the 11/03 cards
running in it.
Other cpus have been run in it namely 11/2 and 11/23 (m8186). You need to
jumper the a16-a21 lines for 18/Q22 and you cannot mix some of the old
non-BBS7 selected IO. The 11/03 used a few of those lines for other
purposes and mixing some of the older cards and newer ones could conflict.
