Using cards

There are three types of card for use with the Cambridge Z88:

RAM cards are for storing your own information.

ROM cards are pre-programmed and are normally called applications; for example PCLINK.

EPROM cards allow you to write information once only, but retain it even when removed from the machine thus providing a secure way of saving your data.

Card information <>CARD

The CARD command, on the Index COMMANDS menu, shows the type and size of the card in each slot. However it will not show an erased EPROM until it has been accessed by the Filer.

Inserting or removing cards

Cards should only be inserted or removed with the Cambridge Z88 switched on.

First enter the Index. Then open the perspex flap at the front of the machine. Check that the screen goes blank. The computer should bleep once as you open the flap. The card can then be pushed in or pulled out. The label on the end of the card should be upright when you push the card home. When you have completed the operation, push the Perspex flap back into position.

Card errors

Errors which occur during the insertion or removal of cards are displayed in the OZ position on the right-hand side of the screen.

A 

message is given if a RAM card is removed, indicating that a soft reset is necessary.

If you remove an application card which a suspended activity is using, the Cambridge Z88 will give a continuous tone and flash CARD until the card is replaced. The suspended activity should be removed with KILL before trying again.

An INDEX message is given, together with a continuous tone, if you have attempted to remove an application card while not in the Index.
