Want information or references on Timex/Sinclair ZX81 hardware,
>>>>> especially expansion bus pinout. <<<<<
Want to interface to Zilog Z80/Z8000 peripherals and the new $10
Seeq 52B13 E2ROM (or EEPROM), which is 'compatable' with 2716
EPROM and 6116 static RAM (see Feb 84 Byte, p343).
In case you're wondering, I want to use it as a cheap development
system for interface to Macintosh serial bus, with Z80 (in ZX81
during development) serving mainly as traffic-director/protocol
handler, so the 64K address range is not a problem.
Thanking you in advance, etc. etc. ,
Phil Stephens
