Hi. Does anyone have any tips to that might make a ROM board that is not responding to be recognized again? The ROM board looks perfectly clean and the gold connectors at the bottom of the chip look fine to me, but it is simply not recognized in any expansion slot. I went into diagnostics mode and all I get is "ROM board not found" when I try to test it. All other boards work fine, and I tried this one in different slots, etc, always with the same result so it's clearly not the fault of the synthesizer. 

Thanks. :)

How many ROMs do you have installed? Also, do you have the latest OS? With some earlier OSes there could be a conflict between ROMS.

Hey Steve,
It's the latest OS on a Vintage Pro. Just seems to be a bad expansion chip. I was just wondering if anyone had some magic tricks to try and bring them back to life. I read one archive message where someone mentioned using an eraser on the gold connectors at the bottom of the ROM. Well, that didn't work... :)

A few years ago I trashed the baby ROM of a P2500 SIMM by putting it in the wrong slot of an E-Mu Ultra sampler. The ROM has samples and EOS presets in the big ROM and P2K presets in the baby ROM. Evidently I wiped out the baby ROM which produced an error not unlike your bad crc error. However, the ROM still worked as an EOS Ultra sampler sound ROM. Its a long shot, but perhaps something similar happened to your ROM. To check for this, find someone with an EOS sampler. And if that's what happend, there is really no way to reflash the baby ROM with P2K presets.

Hope this helps.

Steve

Visually the rom is very clean and looks new. But I did try some 70% alcohol on the gold pins like Ive read to try elsewhere on the web. No dice. Any last ditch ideas?
