o Dual TIL 311 hex latching displays accessible as
output port 4
when in run mode.
Have you considered, say, a small GAL-type device driving standard
7-segment or 5x7 displays instead?
Not a GAL. I want to avoid any non-popcorn parts beyond RAM, CPU and
big I/O chips. I would _consider_ using the same BCD-to-7-segment
decoder that was in the Elf-II; it properly displays A-F if fed $A through $F.
How would you feel about a GAL that was programmed to replace
the original part - with the same pinout?
