    266MHZ Beige G3 mini tower buildup

    Those are 'system-specific' installation discs. Are their labels grey? 'Original' in this context means non-specific to any hardware setup but one that supports the installation, and XPostFacto is used to extend the 'support' to otherwise 'unsupported' hardware. Convoluted, ain't it? de

    Another Macintosh Classic

    You also need to distinguish between countries outside the US. Hong Kong (before the lease expired) was not any of Singapore nor Korea nor Japan nor Philippines nor Indonesia nor Malaysia nor China ... de

    adding os 9 permissions after os x is already installed

    What do you meam by 'add OS 9 permissions'? If you mean 'to install OS 9 HDD drivers where none was before, and after OS X has been installed on a drive', the answer is indeed, 'No'. An HDD must have OS 9 drivers (plural) installed at the time of its formatting if it is even to be 'seen' by OS...

    Replacing PB170 backlight ... with passive PB backlight?

    Tomlee59 has given the definitive answer that you should not marry the wrong cure to the correct cause. Depressingly or not, it also has to be mentioned that the backlights and inverter boards of FSTN and TFT panels in PB1nn series Macs are not universally interchangeable. Inverter boards put...

    Just purchased Mac 512k

    The latter author's claimed experience might have been easier to believe if he had not miscalled acrylonitrile-butadiene-styrene copolymer (ABS) 'acetal-butadiene-styrene'. There is a significant difference. Implicating bromine (the next-heavier halogen above chlorine) may or may not be...

    9500 - SCSI LaCie CD-Rom drive and/or burner

    The 9500 has separate internal ('fast') and external ('slow') SCSI controllers and buses. Is it possible that you (even unwittingly) changed termination or ID on the LaCie drive after successful use of it? Is it a d2 CD-ROM? Whether or no, check that the term on slide-switch is depressed if...

    Just purchased Mac 512k

    Without my wishing to rain on anyone's parade, let me refer back to an earlier discussion in these forums, and the posts that in turn hang off that discussion. We already have the makings of a good Read Me First for case-yellowing. It is in the nature of ABS plastic to age chemically and...

    Just purchased Mac 512k

    Rational enough, but perhaps not obvious. Whether a blob of solder melts under an iron is the net effect of the old calories-in/calories-out bit. If the soldered-in component has a large thermal mass and a wide thermal path in, retention of heat to melt the solder may be impaired if the iron...

    Classic II ROM/FPU expansion board

    PD You may already have come across this, which has leads in other directions. Algernon Apple supported System 7.5 with 6MB (total) of RAM throughout much of his tertiary work, so part of the thread, at least, puzzles me. He completed my wife's (then) studies with 2 x 4MB (10MB total, all...

    ROM on IIci

    Jumper the two-pin header at W1 near grid reference A8 on the MLB, unless you have one of the just-in-case separate ROM SIMM cards in the ROM slot. If there is one of the fabled ROM cards, leave the jumper off the header at W1. de

    Downgrading System 7

    One of my CCs runs 7.6.1 quite comfortably on its (max.) 10MB of RAM (and max. VRAM). Almost sprightly, even, but far from blistering. I have to sympathize, however, with the notion of a lesser System, but no less RAM/VRAM. Macgeek417 has suggested the ideal solution: a custom construction of...

    Just purchased Mac 512k

    In even the relatively-large masses of solder implicit in holding large (in mass or current-demand) components to a power/sweep board, the integrity of the board-to-trace or board-to-land adhesion can usually be assumed. Nonetheless, look askance at obvious messily-reworked joints, and...

    Just purchased Mac 512k

    You could be but a single dry joint, or a few dry joints, away from joy as was zeppelin87. The FBT is a prime suspect in this case, but tomlee59's description of the path to the promised land in the same topic is worth your consideration. A quarter-century or thereabouts of resonance in a...

    Powerbook 520 power pinouts

    MDD 1.25 GHz Dual

    However, given my subsequent acquisition of a copper heatsink for the MDD, installation of Apple's CHUD 3.5.2 (supporting Nap Mode for DP MDDs), and a liddle fiddle with the control-point integers in the info.plist of AppleFan.kext (10.4.11), the equilibrium point for the CPU board is now 36°...

    Installing a new fan?

    Search for posts in these Forums by JDW on the subject of SE/30, and SilenX or 'iXtrema'. JDW spent quite some time evaluating fans for the SE/30, and strongly recommended the SilenX as a result. They use not ball-bearing but more up-to-the-minute fluid-dynamic bearings. There are those in...

    Unhappy PowerBook 100

    There is a strong possibility that one or more cells in an overheating battery contains a dead short. Charging such a battery carries the risk of inducing fire or explosion, in the low-power (as you are already aware) adapter, if not in the battery. Don't charge the system battery again before...

    My 40/80/160 Mb SCSI Hard disk are all dying.

    I haven't one formatted drive in more than 100: SCSI, ATA, 40-pin, 50-pin, 68-pin or 80-pin that is not deliberately formatted with 512-Byte sectors, as opposed to those sinister upstart formatting protocols that use 514-Byte. Was this really your focus, or consistent with the ages of the Plus...
