Five 2 KiB UVEPROM chips produce an amount of 10 KiB ROM.
This card enables us to use a total amount of 14 KiB ROM with the reZet80 PIONEER.
See the memory map and address decoding for more details.
EEPROM chips can also be used although they were not available in the 70s (just in case an easier handling is more important than a 70s feeling).
Bill of materials:
- reZet80 PIONEER 10 KiB ROM card PCB
- 40-pin right-angled male connector
- 5x DIP-24 socket
- 5x 2716 EPROM (or compatible 2 KiB chips)
- 6x capacitor 100 nF
