IC5 is the "fast" PROM. Most of the Memotech boards I have seen use a device made by "MM", although I have forgotten the full name of the companysiggi wrote: ↑Tue Oct 10, 2017 10:34 amThe board itself may probably also be used for 64K ram modules. But AFAIK the Memotech rams contain a programmed chip (PROM?) for address decoding. So you would need to get the appropriate PROM for the 64K board....
Needless to say, this PROM and others like it become obsolete many years ago.
I've got a datasheets somewhere for it.
