Unknows S-100 System

I eventually got a HD box to hook up to that system, although the 34MB Tulin drive in it at the time had bearings that were so bad you didn't want to be in the room with it when it was on. I stuck a ST225 in there and managed somehow to hack the code enough to make that work, more or less. I never did find out where I had to do anything with regard to write precomp, which I'm guessing why I had lots and lots of trouble accessing the last few MB of the drive, though with as small as most software was in those days, I didn't really feel the pinch until I started collecting lots of _data_ rather than software. Which I still do, to a large extent. I'd love to have double-sided drives in the Exec, but never did get anywhere with that. The few bits I had info on didn't look like they'd work with the HD setup -- both involved replacing the CPM3.SYS file, so I never got there. It'd also be neat if there were some way to have the system ROM (EPROM actually) be able to specify a boot from the HD, but you had to boot a floppy to get there. I had lots of fun with it, though. Stuffed all sorts of utilities into a 600K+ COMMAND.LBR which the system would search when it couldn't find stuff otherwise, never a noticeable delay there. Patched the crap out of my copy of Wordstar, etc. ZCPR looked to have some pretty nfity ideas. I don't completely agree with how they went about implementing all of them, though, and maybe someday I'll hack something together that uses their ideas and does it the way I want it to.
