Colorado Memory Systems Jumperless Tape Controller

Went back through my notes--it's not the FC-10 or FC-20 from Colorado that's ISA PNP--it's the Exabyte "Floppy Tape Accelerator", PCB 317235-000 that's the PNP one. Circa 1996, using an 82078. Unlike the Colorado, there's no external drive connector. There are also empty pads for what I suspect might be a data compression processor chip. While both the Exabyte and Colorado 2Mb accelerator cards are nominally 16-bit ISA, the Exabyte uses only the 16-bit additional IRQ lines, while the Colorado uses both the 16-bit data and DMA lines in addition to the extra IRQs. Both cards use 48MHz XCOs. The brief user documentation for both state that they can be used in 8-bit slots; but the Colorado specifies that data rates up to 1Mb/sec are supported in 8-bit mode. For what it's worth... Cheers, Chuck
