The easiest thing to do would be to replicate a PEP-70. It's fairly
easy as it would be one hex board with all of the memory. The only
modification needed for the 11/70 is 4 power jumpers to slot 19. Then
just route short cables from the cache boards to the new board rather
than to the external memory boxes. I wouldn't run an 11/70 any other
way. :-)
Nope. The MK-11 memory box for the 11/70 (there
are others) have
the same memory bus as the 11/750, but the MK-11 don't support 1MB
boards. Believe me, I know...
256 KB memory boards works fine in both MK-11 and 11/750 though.
And if someone *really* have 1MB boards, and an MK-11, and wants to
use them, contact me and I can start explaining what you need to do
to actually get it to work. But it requires both serious hardware
hacking and software fiddling.
I must admit, I find the idea interesting! 1MB boards do show up
from time to time, and my 11/70 could definitely use more memory. :)
