RAM
Internal ram upgrade socket can take either a 32K or a 128K chip.
- 32Kx8 parallel SRAM, 5v, low power, DIP-28
- 128Kx8 parallel SRAM, 5v, low power, DIP-32
- Hitachi HM628128LP
- ISSI IS62C1024L
- Alliance AS6C1008
Chips that would work with a simple SOIC-DIP or TSOP-DIP adapter pcb:
- Cypress CY62128E
If you want to get real crazy, this probably works, although may not fit
