    My powerbook 170 and the tunnel vision

    Maybe someone can enlist the help of a Chinese factory and reproduce compatible panels using more modern construction methods which aren't susceptible to this tunnel vision problem? Then we can get neat things like LED back lighting and such right out of the box. c

    Finally, a Mac Mini!

    Yes, it does seem like it's trying to boot from a faulty hard drive or something, unless you specifically hear lots of optical drive activity while this happens? You can't necessarily hear the hard drive unless you listen very closely. Try doing as nglevin suggests and see if that helps. c

    Finally, a Mac Mini!

    I wonder... if the drive has failed, I may have a spare you can have, if you want it? I can even put Leopard on it for you! I don't see how a bad hard drive would prevent Mac OS X from booting from a DVD, though. If you have another Mac with Firewire (anything will do, but a late G3 or G4 running Tiger or Leopard would be best), try booting it to target disk mode and see what happens? I'm not sure if this was already suggested or not... c

    Wrong capacitors for SE/30?!

    Do you think the cap was intentionally designed to do that? If not, I guess it is a good thing (however, one needs to be careful it doesn't pop off and hit someone in the eye; that would be a thoroughly unpleasant experience, I'd imagine.) c
  5. Yes, it is pretty much shotgunning it a bit to just replace the capacitors without testing them, but if you remove one of them, you'll be convinced they're bad, as most likely you'll find a stinky puddle of electrolyte underneath it. And also, experience has shown that in the vast majority of cases, when things like this happen, replacing the capacitors *usually* solves the problem. And when it doesn't, it's usually some relatively small component that needs to be replaced in addition. Anyway, if you don't want to deal with recapping, a possible alternative would be to simply retrofit a modern PSU into the old PSU's casing. There's a SeaSonic PSU which is very popular for this purpose as it's very small, but I don't recall the model number (it's posted on the forum in a recent discussion regarding upgrades for the SE/30 PSU, coincidentally). The hardest part is wiring it for soft power, but since the SE/30 doesn't need that, it's just a matter of wiring it in and setting the new PSU to always power on when it's plugged in. c
  6. To elaborate somewhat on what I *think* techknight meant, the capacitors in the power supply (PSU) are likely failing, as well as maybe other components. So, to start, the PSU probably needs a recap. And if that doesn't fix it, it might be easiest to find a replacement which is has already been recapped. c

    Super rare Macintosh II Daystar PDS adapter

    Hmm, OK. I can probably afford that in a week or so. I guess I'll take it, if nobody else has! c

    Classic II + FPU = A/UX?

    Would there be any benefit to having an FPU that fast in a Classic II? Running the main CPU at 66 MHz would be hugely beneficial, if one were to ever make it work (indeed, the fastest '030 is 50 MHz, and the 40 MHz '040 (the fastest) tops out at 50 MHz; has anybody ever managed to reliably overclock either one beyond 50 MHz?). But the FPU? I guess it could speed up that 2% or so of software that actually needs it, couldn't it? This, of course, includes A/UX, which brings up another question: would a 66 MHz FPU improve A/UX's performance? For the purposes of this topic, that is a moot point, of course (stock A/UX, in any version, won't run on a Classic II), but if we consider other machines that *can* run A/UX, such as a Mac II, has anyone ever considered hacking the FPU so that it can be clocked separately from the CPU (or bypassing it altogether by installing one in the PDS slot, if possible), overclocking said FPU to 50 MHz or above, and recording any performance differences in A/UX (or any other FPU dependent SW)? It would be an interesting experiment to try! c

    Super rare Macintosh II Daystar PDS adapter

    How cheap is cheap? I actually have a Mac II, and I *might* actually have a use for this (dunno what it'd be (what's it for?), but I'd figure something out), if it's cheap enough for me to afford. c

    Problem with FloppyEmu

    Maybe we can use the same hook-and-patch mechanism to solve that problem? It would be a very interesting experiment indeed. c

    Dry joint example

    Wow! I thought it was a microscope or something! How much does that clip on lens cost? I ought to get one, as it appears to be, among other things, a useful diagnostic tool. c
  12. I have an old Que! external SCSI drive, and I got it to work under... OS 9?... way back when (about 12 years ago). That was neat! I've always been under the impression that, if proper drivers are available for a given platform, and the drive has the proper interface (SCSI, in this case), it will just work, albeit at a slower speed, perhaps (Why can't a new-ish drive from the late 90s work on a 68k Mac at a slower speed? Lack of driver availability would be one of the only reasons I can think of...) c

    Problem with FloppyEmu

    Well, yeah. You're right, of course. There's no valid reason why one would want to use 1.44 MB disk images when they can either create an arbitrary HD20-style image or copy to a hard drive of some sort. However, it would still be kinda fun if someone figured out how to install a driver that allows an otherwise stock Plus to run a SuperDrive at full capacity (to accomplish this with the Applied Engineering AEHD+, they probably installed some sort of driver). This is, of course, mostly an academic exercise, as the Floppy Emu, for all intents and purposes, renders most real floppy-based solutions unnecessary. c

    Problem with FloppyEmu

    Maybe someone can reverse engineer it and then we can implement whatever mechanism it uses in the Floppy Emu so the 128k, 512k, and Plus can use 1.44 MB images! Not that it'd matter, of course.... c

    Help diagnose some AEKII issues!

    Hmm, can't explain the non-functioning lights. As for the other weirdness, maybe it's a bad key switch or two (or more)? What happens if you wiggle the ones in the suspect area? Could be a broken trace too. c
