Description

This is the PCB to build a Tynemouth Software Minstrel Issue 2 computer. The Minstrel 2 is a Z80 based 8 bit computer which is a clone of the original ZX80. It sticks to the original design, the only changes being 16K of RAM and a composite video output with a backporch signal that was missing on the ZX80 and early ZX81s. It can run the original ZX80 4K BASIC or the later upgrade 8K BASIC.

Note it follows the ZX80 design, so although it can run ZX81 software with the 8K BASIC, it lacks the fast/slow mode of the ZX81 so cannot run any ZX81 software which requires this (including most games). If you want full ZX81 compatibility, see the Minstrel 3.

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 built it as a standalone computer with a membrane stuck to a perspex baseplate or with the Minstrel tactile switch keyboard (see other listings).

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. 

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 updated V2.9 PCB with improved video circuitry, in green. This version can be fitted with either a 7805 switching regulator or a 7805 + heatsink (see photos for examples, but note some of the pictures show older versions)

See other listings for a complete kit and a built and tested version.
