RAM and Flash Cards?

  Scales for weighing up options  
   RAM and EPROM packs  

How to decide what to get

The Z88 comes with 32K RAM 'built-in' memory. This is just enough to try out the examples given in the manual before you run out.

If you want to use your Z88, you need more RAM because it uses RAM as working memory and for storing files.

RAM gets used for everything

You should use other devices to back your files up, but the first need to be stored in RAM otherwise you are unable to get them to the other devices.

Expanded machine

RAM should be added (in slot 1 (or slot 2 if using OZ 4.x)) initially. This makes the Z88 an 'expanded' machine, the preferred configuration.

Size of RAM Amount used by Z88 Amount left
32K 8K 24K
128K 40K 88K
512K 40K 472K
1024K 40K 984K

Cambridge Computer Memory Card booklet (500K)


The Z88 uses some of the extra RAM for itself internally for Applications and BBC BASIC. You will quickly discover that you need more RAM than you think.

The following example assumes using a 20K document in Pipedream with a 128K RAM Pack.

Size of RAM 128K
Amount used by Z88 (expanded machine) 40K
Amount left 88K
Additional amount used by Pipedream 20K
Amount required to store the file in :RAM.1 20K
Amount left 48K

Remember If you have not got enough space to save the file to RAM, you will not be able to save it to the EPROM Pack or transfer the file to another computer.

Note If you put your RAM in slot 2 then the Z88 will not be an expanded machine.

FLASH cards

If you have enough RAM, you need the 1M Flash card to save your life's work to before something goes wrong with the Z88. I.e. loses it due to the battery going flat or the Z88 just crashes. Unlike the RAM where you can delete individual files to gain extra space, all the files on the Flash card are deleted when the device is formatted on the Z88. So you need enough RAM to store these files whilst you do that or use a second Flash card to transfer the files across.

What do I do?

I now use the combined 512K/512K RAM/Flash card as I have never run out of memory with 512K RAM and the extra 512K space may be used for applications and file storage. I use an additional Flash Card so that it can be used to transfer files to another Z88.

Sick Z88 & Advice

Is your Z88 not working, or at least not working properly? Has it lost all your files again?

We hold limited stocks of Z88 parts and can get you running again. Give us a call. With the Z88 at a new low price it is often more cost-effective to buy a spare machine.

REMEMBER we are computer consultants who can HELP YOU to use Z88's (and other computers) in most applications. Untitled Document
