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 reply to - (hplabs,ios,allegra)...oliveb!oliven!prs
