What is it?

This is a clone of the 1980s Sinclair ZX80 Computer, the predecessor of the ZX81 and ZX Spectrum computers. This is based upon my Minstrel ZX80 Clone boards, which use real hardware (not FGPA or emulation) faithful to the original design. The only change is the addition of an few extra logic gates to improve the video output for modern TVs and Monitors.

Connected to this is a second board contains a matrix keyboard PCB with 40 individual tactile switches.

This version comes with both the original 4K BASIC ROM or the upgraded 8K BASIC ROM (selectable via a jumper), and has 16K of RAM built in (no need for a RAM pack). Power is via a 9V DC adapter (available as an option). The TV output is via composite video (PAL or NTSC, selectable via a jumper). The power supply and cable option also includes a cable to connect a computer or cassette recorder to load or save programs.

Why did you make it?

To recreate a faithful ZX80 clone, but with the ability to view on a modern TV set.

What makes it special?

These are one off hand built units using my Minstrel ZX80 boards. These boards are also available as bare PCBs and kits - minstrel-zx80-clone

Overlay PCBs

There is an option to include one or two overlay PCBs. These sit on top of the main PCB, with the switch plungers passing through holes in the PCB. There are two versions, one with artwork representative of the ZX80 4K BASIC and the other with ZX80 8K / ZX81 BASIC. The overlay allows a larger area around the switch to fit in all of the various levels of keywords and graphics characters used in ZX80/ZX81 BASIC.

Baseplate

There is an optional clear acrylic baseplate with mounting pillars and feet, suitable to mount the keyboard the Minstrel ZX80 clone.

BASIC Versions

The original ZX80 came with a 4K BASIC ROM. When the ZX81 was launched, Sinclair offered an upgrade for the ZX80 with an 8K BASIC ROM. This version of BASIC is more powerful and is partly compatible with the ZX81. Both versions are included, selectable via a jumper.
