The ZXpand interface for the Sinclair ZX81 Home Computer

This auction is for the last pre-production ZXpand interface produced by Charlie Robson on 15th March 2011, Serial Number #00001.
The interface comes fully working and tested, together with a certificate of authenticity.


The ZXpand interface is a brand new interface for the Sinclair ZX81 Home Computer which provides the following facilities:

  • SD Memory Card reader - for instant loading from / saving to .p files (used by ZX81 emulators)
  • 32K of configurable RAM memory, which can then be set up to use the various hi-resolution graphics schemes for the Sinclair ZX81
  • New keywords are added to the system ROM to allow you to load and save programs, produce a catalogue of files on the memory
    card, configure the ZXpand Interface, and delete files.
  • You can still load programs from cassette as well as using the interface, to allow you to copy files onto the SD memory card
  • Sub-directories are supported on the memory card.
  • The new ROM can be switched off once a program is loaded, in order to allow access to LPRINT, LLIST and COPY commands.
  • There is a built in reset button to reset the ZX81 without having to pull the power lead.

  • Zon-X81 Compatible AY sound interface
  • Atari style joystick adaptor for specially written or patched games
