ZXpand Interface for ZX81 and Timex-Sinclair
The ZXpand interface is a brand new interface for the Sinclair ZX81, and Timex-Sinclair TS/1000 Home Computers.
The ZXpand interface offers 32K of expanded memory (which is configurable to support various hi-resolution graphics modes), instant file access to .p files stored on SD memory cards and more.
The Sinclair ZX81 ZXpand interface will also allow you to connect an Atari style 9 pin joystick port to play either specially written or specially adapted games.
The ZXpand 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.

These interfaces can be purchased easily through sellmyretro.com – we have also now produced ZXpand specific keyboard membranes for the ZX81, which have the new keywords printed on them (so it makes it easier to use).
Even better – not only does the additional AY-module for the ZXpand add 3 channel sound to the ZX81, but you can now couple it with a MrX Sound Interface, to provide 6 channel Turbo AY Sound – creating some wonderful musical possibilities
