When the Z88 came out, there was no facility to 'Blow your own ROM,' This was because the Z88 Application software was supplied on an EPROM card. As larger EPROM cards became available, it was possible to make compilations but there were only a few people around who had the skills to link the applications together, writing addresses on the back of envelopes and using Hex calculators. This all changed when ROMcombiner was written. This allowed users to combine applications themselves. When the Flash cards become available, blowing those were added, so at last, all the applications that were written could be written onto one 1M card.
Now that all the companies that wrote software for the Z88 are no longer marketing their products it is now possible to download the ROM image and blow your own.
The Z88 needs to have the following cards as a minimum configuration.
A blank EPROM or Flash Card to store the applications or files. | |
(Optional) EPROM Eraser to erase the EPROM card (if required). | |
