It would be a fun hack. ---------- Slow by comparison to a floppy? As long as we're only talking about using it for ROM storage of commands and documentation, that shouldn't be a problem. The transfer rate ought to be fine, it's just seek that's slow. For those purposes it shouldn't matter much if it takes a couple of seconds to position itself. The staging idea is good, though, especially if you're using a fast disk for paging: the CD-ROM could pre-load a whole image to the fast disk and then page in pieces as needed (Z-magic). -- scott preece gould/csd - urbana ihnp4!uiucdcs!ccvaxa!preece
