#N:uicsl:21600005:000:466 uicsl!riber Nov 14 11:33:00 1983 I noticed something the other day on my OS9 coco! While looking over the device drivers and descriptor, I found that the cassette port on the coco is unused?. Does anyone out there have anything to utilize this port with? Although I would not use it very often, it would be nice to have access to my cassette under OS9. It could be used for other things too of course. Any sugestions? Please share.

#R:uicsl:21600005:uokvax:3500013:000:709 uokvax!emjej Nov 15 10:44:00 1983 It could be done--you'd need SBFMAN (sequential block file manager) to live on top of the cassette device driver. I don't know if it's worthwhile, though, for the following reason: Radio Shack, in its design of the CoCo, did many, many things in software to cut hardware corners. The spread of OS-9 for the CoCo is going to--heck, it *has* (see the CompuServe CoCo SIG, which is *very* active and worth your while)--show this corner-cutting rather severely. Piling the code that generates the frequencies for the cassette on top of the keyboard scanning and byte-at-a-time interrupts for disk I/O may be the straw that breaks etc. Hardware folks, please comment and correct me if needed.
