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. These are quality Panasonic 'Light Touch Switches', which are good for typing, giving a positive response but without being hard to press.
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.
To recreate a faithful ZX80 clone, but with the ability to view on a modern TV set.
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
These are available as hand built units using my Minstrel ZX80 boards. Either as a kit or fully assembled. There are more options including bare PCBs and various kits here - minstrel-zx80-clone
This includes a PCBs and parts.
As above, but assembled and tested, ready to plug in and go.
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.
