It's one of the software specific version daughter boards replacing an address decoder and/or latch decoder function.
I've seen these before in various RC-85 and RC-96 Controllers. For a combination of reasons, you needed to add or replace this board with software upgrades. The main reason is a ingenious method to prevent firmware piracy. I've told the story many times... you wouldn't think people would go to the trouble to copy ACC Repeater Controllers... but they did. Over to a friends house one time to see an entire assembly line of wire wrap RC-85 Controllers along the side of his work shop. University Kids with brains, resources and a lot more time than free money. cheers, skipp ps: I have most of the ACC RC-85 and a lot of the RC-96 firmware versions in archive. Email me direct if you have specific questions.

Nothing is mentioned in the RC-96 manual. Thanks! 73, Eric Lemmon WB6FLY Yahoo!
