Z88 Hardware

Ram Packs		EPROM Packs
Using Ram Packs with your Z88.   Inserting the RAM pack into Slot 1 of the Z88 The Z88 comes with 32K RAM 'built-in' memory. This is used both as working memory and for storing files. The Z88's memory can be expanded in 32K, 128K or 1M byte blocks by inserting a RAM Pack. A 1M RAM Pack has enough room for around 200 typed A4 pages. If power is lost, through the batteries going flat or if an application crashes, any files that or stored in RAM or unsaved current work may be lost. This is why EPROMs or Flash EPROMs are used for backing up important data whilst using the Z88 on the move.		Save your important files on a Flash EPROM or EPROM pack. EPROMs are used to save files and are like disks on a PC or Mac. Once you have saved a file onto the pack, it will remain there allowing the pack to be removed without losing any data.. Differences between a disk and an EPROM pack. Individual files can not be physically deleted by overwriting them. Instead the 'old' file is marked and the new file is saved at the beginning of the cleared area. This means that if you saved a file that is 2K long three times, 6K will be used. Files are erased by formatting the entire EPROM either by using an EPROM eraser (for the EPROM) or by using the the command (in the Flash EPROM). By using two packs, files that need to be kept can be copied to RAM and then onto another EPROM pack before formatting the full EPROM. EPROMs and Flash EPROMs can be reused again after formatting.
