Magic Desk 1MB cartridge
The cartridge will be supplied with a 27C801 EPROM which will be blank. This can be programmed using a programmer like the TL866 Plus. The EPROM is erasable with UV light.
(The programs listed on the picture is just an example of what it looks like when programmed)
You can use the Magic Desk generator to generate a binary file for your .prg files which can then be burnt to the EPROM.
If you would like me to program a .bin file for you please contact me and I can burn this before shipping.
The cartridge has a RESET button on it which will allow you to reset the Commodore 64.
