OK, I've been happilly bending this machine for a few days now. Got some incredible sounds from it, and I am amazed at how awesome it sounds now compared to it's cheezy stock condition.
Sadly I had an accident - I forgot to un-plug the power from the machine before soldering on the last set of switches directly to the legs of the IC. Now it seems to be permanently circuit-bent. I've removed all the bends, checked closely for stray solder, and thoroughly cleaned between and underneeth the pins of the IC, but have had no luck in restoring the machine to UN-bent condition.
Do any of you good people know of a way to reset the machine? Is there a way to re-boot the chip, or is it possible to replace the chip with some other equivilent?
The drums appear to have completely vanished, the accompanyment is well out of tune, and the patches are all st-u-tt-e-ry. In fact it sounds just like one of the bends I was experimenting with (except that it's permanent!)
I'd be gutted to have to abandon the machine, as they're quite rare I gather...
Well, from a description on the tablehooters site there's a CMOS RAM chip with a big electroytic backing it up. Try shorting across the chip's power pins for a few seconds to discharge the cap.
