I second everything said here.
Funny though, that they'd use 2114's together with a 6845. I believe DRAM's
were cheaper than SRAM's then, as it is now. The 6845 handles the refresh of
dynamic RAM's, so they could as well have used cheaper DRAM's. The only
thing I can think of are that you'd need at least 8 DRAM's, and only 4
2114's.
Does anyone have schematics for an 80 column card for the Apple 2? I have
lots of old Hercules compatible cards, I could make my own 80 column card
:).
