The machine we're testing on is only a 20Mhz machine (mainly so we can get a "down-to-earth" idea of the performance), and that's probably why we've had such horrible luck with software polling on the various CD-ROM interfaces. We have had a couple that would work, but others, including the Mitsumi, just never worked out. Generally the faster the machine, the quicker the response time on software polling. Argh… I'm sorry you went through all that effort and didn't get it to work. Please, try it with the DMA enabled and let me know if you have any success. In addition, you might also want to try using the "1.5" Mitsumi driver package in the software library. I know this version worked in-house on the 16-bit interface, and the drivers which came with the drive worked (but I don't know what version those were, sorry). Well, in any case, please let me know how it goes! Michael O'Connell Online Support ICOM Simulations 708/520-4440
