Hello Gerry, and Welcome!
Those old devices are not going to work with the modern Ganzframes, unfortunately. The Kasina and Limina Ganzframes (and DeepVision Ganzframes) are designed for 6-channel input (R/G/B x 2) which only the
Kasina and Limina can supply.
You should consider upgrading to one of those devices. Their features and capabilities are pretty impressive. And your older products don't owe you anything. That's a a pretty long life for a piece of consumer electronics!
If you looking for a manual for your Polysync, maybe check with
Robinhood? I think he owns one of those ancient machines...
