SuperBoard done; which might be quite a while yet.
But unless they have a web
browser what do you need 512K memory for?
No wait ... a web broweser with graphics has to fit in 64k of memory.
OK, just kidding, but - to venture into where my brain
& dynamic memory
part understanding, the 41256 uses a particular refresh[1]
which newer memory doesn't deal with well[2], so going *beyond* 512K is
problematic.[3] *If* I can figure out how to get 512K of SRAM to work in
a CoCo3, going *beyond* 512K might become a bit easier.
Good I can sell you 24 bit
computer design good to 2 MHZ with real 12 bit
bytes ... :)
