Trumpcard for the Jupiter Ace, by Innovonics

This card was produced by Innovonics to allow the use of ZX81 peripherals with the Jupiter Ace.

Trumpcard was originally designed as a mechanical and electrical link between the Jupiter Ace and ZX peripherals. To maintain flexibility and programmability the two connecting edges are quite separate. In this way the constructor can colour code and interrupt the signal lines as he pleases, both for experimental and permanent applications.

With the exception of the chip select lines, /WE on the ACE and RAM/ROM CS. on the ZX81, both computers share the same bus albeit in a different configuration.
