Description

This module is designed to be fitted inside a ZX81 in place of the original RAM IC(s). It can be connected to provide up to 16K of RAM.

It is activated by the ZX81's RAMCS signal, in the same way as the standard internal RAM. This means that any peripheral that inhibits this signal to present itself in some or all of the address space normally occupied by internal RAM should function normally when connected to a ZX81 that has this module fitted.

This module is designed for issue 1 ZX81s. However, with a little extra effort it can be fitted to an issue 3 ZX81. Please refer to the installation instructions for full details. For fitting to an issue 3 ZX81, all the connecting pins on the right hand half of the module must be absent. You can de-solder and remove them or at the time of purchase send a message requesting a module that has not had these pins fitted.

Click here for installation instructions.

Delivery: Price includes delivery to UK and associated postal regions. Postage to anywhere else is £2.20 extra for up to 4 modules. Please ask for a quote if you want to purchase more than 4.

Payment: PayPal or transfer of the exact amount to a UK bank account accepted. Account details will be sent on request.
