Hi all,
I got 2 Memory Boards (National semiconductor) several weeks ago
(each 1MB). Somerwhere on the net, someone says, that these can be
used in VAX 11/7xx. Can I use these boards in my PDP 11/24, too ?
I don't know yet, if 32bit boards can be used on 16bit machines and
I'm afraid of putting them in and seeing some smoke when turning on
the machine...
I doubt it. The 11/24 uses UNIBUS memory, and the 11/78x and 11/750
both have a special memory bus and controller (or multiple
controllers). I don't know enough about the 11/730 (& 11/725) to say
"definitely no" but it seems quite unlikely that they used straight
UNIBUS memory.
