1M write LED upgrade
1M Flash LED

When the 1M Flash card was designed, the circuit was added for a 'write' LED to be fitted.
Unfortunately, the Cambridge Computer cases used, were not strong enough for them to be used.
This has all changed now in 2020 due to 3D printing.

Tony has designed a stronger case, allowing

1. the 38 pin connector to be more robust and
2. the LED to be fitted.

Existing users may take advantage of both these functions by sending their 1M Flash card(s) back to have this upgrade done (at extra cost) whilst new users can order and use them straight away at no extra cost.

1M Low Power RAM Card


This uses a modern static RAM chip which gives the following advantages:-

  • 1M RAM
  • Low Power
  • Longer battery life.

This is a RAM pack.
If removed, a HARD reset is required

Universal Power Supply
Universal Power Supply

When the Z88 came out the Mains adapters were built using large and heavy transformers, forcing users to either leave them at home or having two supplies, one for home and the other at work.

This power supply is the modern lightweight equivalent

  • Input voltage 90-264 VAC
  • Input frequency 47-63 Hz
  • Size 91mm x 36mm x 38mm (3.6" x 1.4" x 1.5")
Use it either in the USA, Europe or anywhere in the world.
