I built up two versions of an unbuffered controller; the first using 74LS00 "glue" chips on an ISA proto board and the second, a PCI card using 82C55AC's (10 MHz 8255's); one for control and the other for data.  The ISA board could not keep up using DMA or programmed I/O with the Fujitsu, which was firing out data a bit faster than 1 usec. per byte.  The PCI board could just barely keep up (this was using 32-bit code; I suspect that the board has a few too many wait states buried in the FPGA used for interfacing).

The Fuji drive is of traditional reel-to-reel open construction, and while it has a high-speed mode, I don't think it could be called a "streamer" in the sense of the Cipher.  It's built like a battleship and weighs probably close to 150 lbs.

If I can't make heads or tails of the Computer Logics board or obtain another board with similar functionality, I'll probably  move next to a dedicated microcontroller (I've got a RabbitCore 2000 kit around here somewhere) and a USB 2.0 interface to the PC.

Cheers,
