ZX81 keyboard overlay sticker Jupiter Ace / Minstrel 4th

These are stick on keyboard overlays that can be applied over a standard ZX81 or ZX81 replacement membrane.

This one features Jupiter Ace keywords and colour scheme, useful if you want to fit a Minstrel 4th in a ZX81 case.

Note there are two problems with these overlays. Firstly, due to the design of the Jupiter Ace, the bottom row is offset and the shift and symbol shift appear on the left, leaving the letters further along. Secondly, I made a mistake and the up and down arrows on the 6 and 7 keys are reversed (6 was down on the ZX81, but is up on the Ace).

No keyboard membrane or computers are included in the listing. Only the stick on keyboard overlay. 

Some of the photos show different stickers, but are included to demonstrate fitting.
