Hello I bought a few ISD Shockwave machines from a auction a few years back. A few of them have unclearable Vector errors and dead batteries. I recently found out that there is a set of two eeproms that can clear/fix these problems. I wanted to know if anyone knew where I could get a set of these or the program file so I could burn them myself. Also, any paperwork/shcematics/pinouts that I can get for these machines would be much appreciated. The board has an ID that says "ISD3321 BOARD REV 2.1". Thank you much appreciated.
