After many years, experiments, variants and proposals, it seems that this cheap interface with only two chips (memory and CPLD) will be put into the production. :-)
With a little bit of imagination, we would think of this board: - 2 MB external RAM, one-meg compatible, with readable ports - or 1 MB RAM and 512 KB KB external ROM - plus 512 KB of the divIDE memory model - DivIDE memory paging model by 8 KB (also for ext. ROM, please) - ram pages backups (256 KB or 512 KB standard memory snapshots) - memory setup through a NMI menu (similar to the "speccyal" PROFI interface) - Speccy 128K RAM paging (a small modification on the Coupe´s motherboard is needed) - NMI button (jump to the menu) - external ROM ON/OFF button (system start with a modified ROM, ZX ROM or a special program/menu) - SD card slot (standard size, please) - size of the smallest old FAMICOM cartridges (hence a case is available) Some space still left on the board? What about to add 3 D/A converters (8bit stereo - 16 bit mono, or any other 6 channels equivalent) and to set (change) output ports through a NMI menu, in order to achieve both EDDAC and (partial) Surround compatibility?
