Hmm...wouldn't be Alexis Rosen, perhaps? >Now for the questions....Can a IIx deal with 5-10 simultaneous >users (and a trailblazer running on another port)? Also, I Evidently his does.... I suspect that if your bunch of users isn't doing anything more exotic than reading mail and news and the occasional compile, (the usual activities on pub. access Unix sites :-), 5 or so users shouldn't be a problem. One probably should have at least 8M, if not more, and pay attention to upping the defaults on various kernel config parameters, but it should be doable with little problem. I let a friend of mine log in on my Mac IIx to read news, and usually can't tell he's there unless I look at the modem lights. As for the TrailBlazer, if you're running it on the built-in "dumb" serial ports, it *will* load the system heavily (my measurements usually show ~40-60% of the time being spent in System mode during uucp downloads on a T1000; full TrailBlazer+ speeds would probably load it more). On practically *any* "personal computer" Unix system, you're much better off having a TrailBlazer on a port on a "smart" serial card (with on-board coprocessor) to take the load of handling ~1400 serial port interrupts/sec off of the main CPU. At least one such "smart" card, the Taniwha CommCard, exists for A/UX. (Note that if you're going to have 5-10 people on, you're gonna need *some* sort of serial card in order to give you enough RS-232 ports to let all those people on *anyway*, so one might as well get one or more "smart" cards...) >thought GNU was boycotting apple products. Wouldn't this >include AU/X? So what? GCC for A/UX can be found in the /systems/aux/gnu directory on wuarchive.wustl.edu.
