My Sider hard drive seemed to be one of the supply-defective ones, so I sent it back and upgraded to the new version. The newer version has a built-in safety feature that does not allow the Sider motor to startup until the Apple's power is started. It also is indeed much quieter than the previous version, but it does still make a barely perceptible hum, ok if you use it at a site and not at home. Ours has been used continously for the past 3 months non-stop to operate an Apple-based BBS, so the power problem is no more. > I am pleased with its performance under CP/M, DOS 3.3, and especially > ProDOS.

[...] I just wish First Class had made a provision to let you format the drive ANY way you wished. Ergo, only formatting for DOS and PRODOS. I don't use CP/M that often, and hardly ever Apple Pascal. Wouldn't it make sense to be able to format only for the OS'es you used instead of having those nagging 100K or so worth of unusable space lying around doing nothing? > > >>> TO ANY PRODOS USERS > I am so impressed with the Sider's speed under ProDOS that I want to > start using this operating system much more.

Pro-Byter has many good Prodos-based utilities you can use to learn more about Prodos including a disk editor that can edit raw sectors on hard drives, and other goodies. Their obligatory tip book which comes in this package is not only a scream (or moan, if you prefer) at times but has lots of tips & tricks about Prodos. Sorry I don't have any prices on hand, but a quick look in any good Apple // mag would set you on the right path. On another note, I vaguely recall someone mentioning how he was able to do enough futzing with interrupts on the Apple Cat II Modem so that he was capable of doing terminal emulation and debugging a 6502 program at the same time. Forgive me for not remembering your name if you're reading this, but whomever you are, could you post or email to me a short explanation of how you did it if you could spare the time? I recently bought an Apple Cat Modem with a 212 option, but the Advanced Programmer's manual doesn't seem to help me much with interrupt handling.. Multitudinous thanks in advance.. Jose M.
