Reading the Wikipedia summary of that, it's pretty clear that /srv is the correct place - it's for files and other data that the machine serves. If the shared file store was to be externally writeable, well, that would run counter to the stated semantics of the /srv directory - but it would...

Nicely done! I know you've already got something actually working and the point is now moot, but I _believe_ (haven't tried it out in person) that pretty much any transformer with a relatively equal winding ratio would have worked. The goal isn't to do anything fancy with pulse shapes or...

I'd also like to clarify, the whole "absurdly bloated list of peripherals" thing was meant as _examples_ - I kind of got stuck on the minor question, "just what _could_ I want to have portably hooked up to my KM switch?" Despite what I now see were appearances, I didn't mean to imply anything...

Ah, I see. That many people telling me "you misread that!" is a pretty solid hint. :¬) I also hasten to agree, you're each entirely correct; it was always a KM, not a KVM. I absent-mindedly used the wrong initialism as shorthand for the "dingus that remotely operates several machines from one...

Summarized, your original goal was a cross between "the poor man's lots-of-monitors" - which enslaves external computers to run them, rather than hosting an implausible number of on-board video cards - and a normal KVM. The combination would allow you simultaneous control of many machines via a...

Further thoughts: - Your original "magnetoisolator" should work just fine for the power-on function; if it isn't broken don't fix it. - Why would you need to speak two different protocols at once on the Mac? It's not complicated to convert edges to levels; a simple set/reset flip-flop on each...

Well, _ground_ is always connected AFAIK. It's only the V+ supply that might be absent depending on the powered-on-ness of the Mac. Edit: On machines with soft (keyboard) power-on, the ground & power lines are always powered far enough to tell whether that button has been pressed. That...

I haven't sat down and analyzed your proposed circuit. I doubt I really know enough to check your work to any meaningful extent. That said, if I were to undertake a similar project, I'd probably have started with the technique used in LocalTalk & PhoneNet dongles: a tiny little transformer...

Bwahahahah! That is an AWESOME illustrative parallel. :¬)

A bunch of small random thoughts emerge in response to this thread. In no real order: First topic (annoyingly long): I vaguely recall that Apple released two different serial cables in the early-Macintosh era (by which, in this case, I more or less mean "the span when at least some...

Ah, but in that time period, it would cost a good deal _more_ to properly manufacture a single-piece adapter of the type you envision. It would have had similar costs to the cable version for the connectors on each end and the assembly costs of having some schmuck solder all the connections into...

There actually was a _very good_ reason they did it that way. Alas, since I have no idea how much anyone here knows or does not know about the hardware parts of vintage RS-232 stuff, I'll have to go into a bit of boring background detail before I can plainly explain why: RS 232 style...

I've been a bit out of touch lately—are laptop-sized CF or SD adapters no longer a feasible approach? I could have sworn they were cheaper than $200, but as I alluded to, it has been at least a year since I investigated the topic in depth.

There's one I used to use called, if I am remembering the name right, a DaynaPORT. Good luck finding an image of the driver diskette though.

I think this is one of the most impressive "Well FINE, I'll just do it myself then, O thou self-proclaimed 'suppliers' who refuse to actually supply" that I have ever seen or heard of! If I knew of a haberdasher who hadn't gone out of business 20 years ago, I'd go buy myself a hat specifically...

About 15 years ago, I drove a fellow home (my job at the time was "professional designated driver") whose company had developed a method of building lead-acid batteries which, though having completely traditional chemical composition, had greatly improved energy density by reason of using...

Unless I am misremembering, the 8100 IS one of the initial PCI Power Macs.

CC_333, I was unaware that windows with exposed heating traces were still a thing in new vehicles. I stand corrected. As to the possibility of dual-layer manufacture, you are probably right about it not being done that way; for all I know, they just stuck a layer of plastic over the traces on...

I believe the “killed 9” message would be the OS under which the util was run reporting to you that, for whatever reason, the util was halted by some other piece of software. The Unix command for sending a control message (“signal”) to another running program is called “kill” because that is its...

Says it is good up to 220 VAC on mine. Better read yours to be sure though.
