Sinclair ZX80 / ZX81 / Z88 Forums

Hi All I have a few add on keyboards and would say that the fuller is the slickest to use with the best feel, but suffers the usual key press lag as it does not have the memotechs buffering.

He describes various differences between old and new roms and how a few old roms are fitted with the add on to correct arithmatic errors caused by just three bytes of c...
