Hi,I am wondering if any electronic wizards out there can give me some advise on an idea i have?
I have an old yamaha drum machine that has dated drum sounds in its rom,the rom is in the form of a cartridge that plugs into the back of the drum machine,I would love to replace these dated drum sounds with modern drum sounds and was wondering if it is possible to read the data(drum sounds)from the existing rom and replace it with new data(modern drum sounds) and program them onto a comparable eprom and then put the eprom into the cartridge.
I have opened the cartridge and there are two chips,
chip 1 is a M5M23C100-512P 645100
chip 2 is a M5M23C100-513P 643102
Both chips are made by Mitsabishi.
I presume the two chips hold the drum sounds as there are 28 drum sounds so I'm guessing 14 drum sounds each chip.
I would be happy with 14 new drum sounds so if only one rom is needed thats fine.
Does anyone know anything about these chips and is what I'm proposing possible or am I dreaming.
Would love any info on this,
Thanks for your time,
Steve.
