/* Technical Specifications */
This rombox allows individual settings for each rom(via a jumper block). This way the rombox has a maximum capacity of 224Kb (7*32Kb). Also individual roms can be turned on/off by setting a jumper.
 
Testing indicates normal decoding is done of the ROM select I/O port: e.g. Bit 13=0, all others are ignored.
In addition, ROM select IDs do not repeat, so that a ROM in slot 1, only exists in this slot and no others.
