Hi Daniel & grant, thank you for your answer ! I attach to this message pictures of the card and the script I used ( in French, sorry.). I can also supply rightly programmed 27C801 EPROM, or even a complete kit with all the components ( a few indeed ). If someone is interested in such a device, I can launch a batch at OSH Park for PCBs and send them once I've received them. For now, I filled the ROM to the brim with 256 SYSEXes picked up at random -)Īs said, the prototype seems to work very well ( though I didn't test every single patch.) bin file to be sent to the EPROM programmer. I had to write a ( rough for now ) Python script to extract datas from SYSEXes ( basically to remove the MIDI-dedicated bytes ) and to build the. There's no mystery in my design, based upon the original ROM card circuitry supplied by Yamaha, which I extended the adressing bus with 8 additional lines controlled by DIP switches for highest adress bits, allowing selection of one of the 256 banks. On iPad, easily import using iCloud or the Files app.I was fed up to boot the computer each time I wanted to try a new SYSEX.so I designed a ROM card for the DX7 built around a 27C801 EPROM ( 1MB ) and ended up with a perfectly working device able to store 256 x 32 = 4096 patches.whereof to stay awake late in the night before needing to erase and burn the EPROM again.
