Central Point Option floppy controller

Given the current discussion, has anyone looked the Central Point "copy card" floppy controller over? I am looking at one of mine right now, and to my limited "PC" eyes it seems fairly normal. Barely the length of a short ISA slot, with fingers on a edge connector as well as a set of header pins for the floppy drive cable. It has one main chip: Transcopy 3 c CPS TC19GO32AP-0036 Japan 8819EA! the ! could be just a vertical line. Its about 8051 sized, maybe 60 pins. There is a 48 khz crystal, and a 1987 copyright. Two sets of jumpers seem to select between PC/XT and AT/Compaq, another set looks like DMA1 or DMA2. Remaining chips are a LS245 to the ISA bus, a 7406 by the PC/XT jumpers, and a 8812S UM8326B next to the crystal. This is one of the cards I check every old PC I see for.
