This is a keyboard designed for use with my Minstrel ZX80 clones but could be used for many other purposes, anywhere there is sufficient IO to drive a matrix keyboard such as other 8 bit microcomputers, Arduino or Raspberry Pi projects.
The 40 tactile switches are arranged in a 5x8 matrix, with 8 sets of 5 keys in a row (12345, 67890 etc.). This matches the layout used in ZX80 and ZX81 computers, and can be used with a ZX Spectrum is the rows are re-ordered when wiring up the cable.
The switches supplied are high quality Panasonic 'Light Touch Switches', which are good for typing, giving a positive response but without being hard to press.
I have used various keyboards with the Minstrel clone but wanted to design one especially for it, to match the design and size and pin connections.
These are designed to match the Minstrel ZX80 clone and can be plugged in directly with suitable connectors (supplied).
These are available as a PCB only, as a kit of parts, or fully assembled and tested. Both include the PCB, 40 individual tactile switches, 8 way and 5-way connectors and 4 pillars and screws which act as feet.
There is an optional clear acrylic baseplate with mounting pillars and feet, suitable to mount the keyboard and a ZX81 shaped board (such as the Minstrel ZX80 clone or ZX Max 48 Spectrum clone, or even a ZX81).
No Minstrel ZX80 clone is included, the final photograph is a 'serving suggestion'
