Hello,

I would like to order 27C160 EPROM but confuse between what to chose.
27C160 50F1
27C160 120F1
It's most be a speed for transfer data, no?
Whats is better, 50F1 or 120F1 ?

Those numbers are measured in nanoseconds from when the CPU changes the address, or asserts /CE, to when the output is guaranteed valid.

With the sole exception of maybe the PC Engine, both of these speeds should be fine for every 5V console I can think of.
