  1. Bwah???? I know the SCCs are still being made. They're a flexible solution to a broad class of problems, and there would be no economic reason to discontinue them. (The specific parts made in the 1980s and 1990s have in many cases been replaced by newer equivalents made with better process technology, but that category of part is not going anywhere.) No, I was speaking of the specialized I/O controller ICs that, for a time, were produced by third-party chipmakers to drive combination serial/LocalTalk ports for builders of Mac peripherals. As in, the specific parts I was
  2. Ah, I see! I had a vague idea that the timing might not work out so conveniently as I imagined in (for example) an environment with poor RF reception, but I didn't realize the concept was so implausible right down to the foundation. It does seem kind of obvious in hindsight, though. I really should try to spitball some numbers on that sort of suggestion before raising it in public. I'm also intrigued by those details about a mistaken belief that the protocol-identifying numbers could be treated as distinguishing characteristics. This sort of thing is what keeps retrocomputing so in
  3. Some random thoughts on this, in no particular order. Train-of-thought the first: - This is not an entirely new idea. Technically, the AppleTalk network-protocol family works natively over wifi just as well as it ever has over Ethernet cabling, even if the simple market forces of having to continuously reinvent the wheel did eventually impel Apple to abandon it wholesale in favour of Internet protocols. As you may or may not have reason to personally recall, the end-user experience did not match that; the tragic (and cringeworthily avoidable) cause follows, but first, s
  4. I suspect a lot of people are in that situation! I've not had time to mess with any of mine for years at this point, but disintegrating case plastics have been the single most un-bypassable repair issue for all 68k PowerBook models for more than 20 years. Nearly anything else that breaks on such a machine can be substituted for in some way - even the batteries can be totally rebuilt with enough work - but there's been no real source for case parts.
  5. I suspect that most “IT WON’T BOOT” issues with these are independent of the system version and, to some extent, even the hardware. I know that only some optical drives are Mac-bootable, and that’s a characteristic of the drive mechanism; but in the pre-USB days, whether you could boot from a lot of the more hard-drive-like removeable-disk technologies was solely dependent on whether the disk was formatted with the correct drivers (just like if you were to attempt booting into Mac OS 9 on a late-model Power Mac, but your boot drive didn’t have OS9-compatible drivers installed). IIR
  6. 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.
  7. 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.
  8. 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 to tip to you!
  9. 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 "foamed" (extremely porous) lead electrodes, which naturally had vastly greater surface area than the traditional simple lead plates… or so he proudly claimed, at least. It would be interesting to find out if they ever succeeded in commercializing that. You could in theory run your Portable for twice as long
  10. Unless I am misremembering, the 8100 IS one of the initial PCI Power Macs.
  11. 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 the windows I have seen. It's not like I have ever examined one very closely.
  12. 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 most common use; the command to immediately and unconditionally halt another process in its tracks and wipe it from the list of running programs is “kill -9”. (The minus sign is not part of the number, but rather a quirk of Unix command lines; it tells the kill utility that the text immediately after i
  13. Says it is good up to 220 VAC on mine. Better read yours to be sure though.
  14. Yes they still use resistive defrosters. The modern ones have the traces between the layers of glass where they can’t get damaged though. As to the repair method, by the time I was old enough to have a car with a rear defroster, it was of the newer type; I have never actually needed to carry out such a repair and do not know anything about it, beyond that it is possible and was at one time a fairly routine operation. Sorry I can’t be more help.
  15. Well, I agree that the loss of “just turn it on and, presto, nostalgia!” from vintage Maccery is a bit of a downer, but I have come to see it from another perspective after giving the matter some thought over the past few years. The way I look at it, our fellow retrocomputing enthusiasts who came to the hobby through earlier systems (or less well-engineered ones, in a few regrettable cases) have been dealing with uncooperative and/or fragile hardware for a long time, but they get no reduced levels of enjoyment from it; it simply becomes necessary to allot a greater amount of time to the ca
