Depends from CP/M, yes.
From basic in Eprom, no.
?
Keep in mind when you do ram banking your changing the active memory map
and stuff may disappear or end up in the wrong place.
?
The memory map is not at all explained.
?
Base machine (no SIO) rom is lower 32K and ram U2 is always upper 32K.?
At reset EProm U3 is the lower 32K.
?
Add SIO with standard AS6c1008 128k byte ram...
That ram exists as one of 4 banks of? in the lower 32K or as 32K eprom.
How they are selected is the Bank register U5, memory decoder U4,
and bits from the output of the 8250 register.
?
Picture included of what the memory map can be logically.
