I just hada eureka moment.
Preparingnotes for the EPROM project I had a look at the schematics and then it hit me.
Practical problemwith EPROM emulation are the 2-byte wide parallel interface needed.
What ifwe skip that side of the memory control and let the clock on the voice card simplycontrol a modern serial EEPROM, or better - a (micro)SD memory card?
Write upand notes on its way, updated frequently so for those interested pleaserefresh. And as always, corrections and direction are welcome.
