Commodore PET Deluxe Keyboard FULL KIT

This is the full kit to build a keyboard for a Commodore PET computer or Mini PET kit.

The board is the same size and has the same mounting holes as the Chiclet keyboard on the orignal PET 2001 and is also the same width as the original Mini PET, so goes well with that. It can't be used as a direct replacement for  the 2001 due to the overlay PCB, but it can be fitted without that.

The layout is that of the Chiclet keyboard, incuding all the graphical symbols. It is electrically identical to the normal / graphics keyboard on later PETs (20 key numeric keypad). It is not compatible with the business keyboard on 80 column PETs (11 key numeric keypad).

It is also useful for bench testing Commodore PET boards due to it's small size.

This uses 73 12mmx12mm tactile switches. The white ones I use are Omron B3F-4050, light touch switches that are quite nice to type on. Beware of the cheaper black or yellow versions which can be hard to type on. It is worth spending the extra to get the light touch versions. 

The keycaps are 12mmx12mm clear caps and 10mmx10mm white buttons. A sheet of paper is supplied with printed keycaps which can be cut out to fit into those caps, and give a very nice effect. Two copies are included in case you mess up any cuts. Also included are a few corrections. The check pattern on two of the keys on the PET Chiclet keyboard didn't actually match the font ROM, so I have correct those. Also the dot and colon were not the same colour as the other punctuation keys. The correct and original versions are supplied. 

I have not been able to locate double width versions for the space or enter keys, so they cutout is for a single 12mmx12mm cap as all the others.

The switches are installed in the base PCB, and the top PCB holds them in place, mounted with 8mm standoffs (not included). 

This auction is for the PCBs + switches + keycaps + pillars + connectors only. No PETs or Mini PETs are included.

See my other listings for simpler versions which use 6mmx6mm tact switches.
