PSS-470? Think that's what it's called...
Hers some sounds from it.
MORE INFO: It seems to use YM3812 chip, also used in adlib sound card. So it's FM. That keyboard has a little little drum computer, and you can short circuit the rhythm chip to other things, and make the bend sound rhythmic, as heard in the first sample above. The rhythm modulates the settings on the operators in the FM chip. The other bend fucks with the CPU.
I bought it at goodwill, 6 years ago, for $24.00. Now they're on eBay for $70~100. Score. Probably won't sell it though.
