Descrição do ficheiro

This is the PCB to build a Tynemouth Software Minstrel Issue 3 computer. The Minstrel 3 is a Z80 base 8 bit computer which is a ZX81 / TS1000 compatible. It has 32K of RAM with high resolution graphics support, and improved composite video output where the orignal TV output would have been. 

The PCB is the same form factor as the ZX81, so can fit in an original ZX81 case and use the original (or a modern replacement) membrane. (note the video out connector is in a different place on the TS1000, so those cases are not suitable withtout modification). You can also build it as a standalone computer with a membrane stuck to a perspex baseplate or with the Minstrel keyboard (not included).

This auction is for a PCB only. The parts required are all through hole 0.1" pitch, and are all modern parts still in production. 74HC series logic is used giving the board a current consumption of around 60mA. It can be built with 74LS TTL chips (but not a mix of TTL and HC or any other logic series), the current consumption is then around 200mA.

Parts availability is a little tricky at the moment, so make sure to check the parts list (attached below) to ensure you can source all the parts required.

This is the last stock of the V3.5.3 boards.

If you don't fancy trying to source all the parts, full kit versions of the Minstrel 2 and 3 with built in keyboards are available from The Future Was 8 bit.

Questions and Answers

  • Pregunta For earier versions LS chips are recomended HCT should work. For Minstrel 3 HC are recomended, LS can also be used. Will HCT work with Minstrel 3 as well?

    Afixado perto B***l (9) - 01/12/2019  16:39:22

    Resposta: All HCT should work, but I haven't tested that. As long as they are all the same series it should be OK.
