Hi guys,
I was a bit intrigued by an idea I just had to make my own sound ROM cards. Tell me if you think this is possible...
Here's the story.Equipment:Casio VZ10M rack synth
Casio RC100 ROM sound card for VZ10M
EPROM chip equivalent to the RC100 chip (27C512 PROM)
Proposition:If I make up my own sound patches on the VZ10M and then, after doing a full bank dump to computer by sysex, turn that sysex file into a ROM image? And after that, use it to make my own sound ROM card by burning the same ROM chip (or EPROM equivalent) that is in the RC100 ROM card (a 27C512 PROM)?? That way I can make up a whole series of ROM cards of my own sounds by cannibalising cheap RC100 cards.
Why would I want to do that instead of just buying the RA-500 RAM card designed for writng your own patches??
1) Because I just bought one that cost me $100
2) every ebay auction I see of them ends up about that price
3) They are very rare and you don't see them much
The RC100 ROM card is much more common and go for a lot less, so tha't where the idea came in.
Also the advantage of having a ROM of your own sounds means you don't have to worry about losing the contents because the card's backup battery went flat.
What do you think?? How would this be done? How do they have done this in the Casio factory where they make the RC100 ROM cards??
Cheers, Graham
