    PowerBook 500 series PCMCIA module Rev C teardown

    A little bit of info to add: I recently acquired both a Rev. B and a complete boxed Rev. C expansion module. When attempting to install the Rev. C’s included PC Card Software 2.0 with the Rev. B card, the installer generates an error saying ‘this software cannot be used with this module; it must first be upgraded.’ This suggests that there was once a way to upgrade Rev. B modules, probably by reprogramming that Flash chip, but I have seen no references to any upgrade procedures. Maybe it was an Apple Service-exclusive procedure not available to the end users.

    The cursed Clamshells

    Necropost! I ran across this thread and a couple others while looking up suitable replacements for bad clamshell iBook LCDs. I’ve found a few non-Samsung VGA units (made by Torisan) that should be a direct fit but with better contrast ratio. I also found the XGA upgrade info linked above. Research has led me to find a number of panels that will fit with the OE Samsung cables so that the unobtainable LG cable isn’t required. However none of them have so far had mount points identical to the original VGA screens; they’re either in different spots or are the slim near-frameless types for the iceBooks or 12” PB G4. Im still working on it but if anyone is interested i can make a new thread regarding my adventure including a list of displays.

    Quadra 610 PDS slot

    The 610 and 660AV PDS slot was unique to those two machines. They could either be fitted with a right-angle PDS adapter that provided a normal 68040 PDS (used for the DOS Compatible card or a PPC upgrade) or a right-angle card that provided a single NuBus slot capable of fitting any standard 7" card. Mostly, though, they went unoccupied, just like the bulk of the non-AV versions of the 6100. The AV section of the 660AV and 840AV was baked into the logic board itself; there were no separate cards to add it in like in the first gen Power Macs.

    Original Hackintoshy Thing

    That floppy drive is certainly interesting. Fujitsu never built GCR floppy drives for Apple. Maybe they were intended to be used in 3rd party external units, of which I have seen a few examples using non-Sony drives. Epson made some, too, for sure used by Outbound in their Notebook clone series. If you don’t already have a buyer lined up for your ATS hack-a-Mac, consider dropping a post in the Trading Post. I’d be interested, for sure.

    CD-R drives tray height clearance

    Anything made by Panasonic/Matsushita will fit perfectly, since they were basically the only OE supplier to Apple for optical drives from 1996-2000ish. You may also be able to get a Sony or Pioneer unit to fit but that’s a maybe, not a guarantee. Anything with a flip-down door (common on TEAC or Mitsumi drives but also some Ricoh units) is obviously a no-go with any bezel. I usually save fancy non-conforming optical drives (Ricoh or Yamaha CD-Rs, Nakamichi CDROM changers) for clones or external SCSI cases.

    Bolles finds

    I was on mobile so was not inclined to try to dig up and quote the specifics (i hate touch screens), which is why i said “may not” instead of “does not.” After looking through the original 601 UM on a proper computer, buried in chapter 8 it appears that the 601 will support operating at bus multiples other than 1:2 but for that you need to do some clock skewing with that chip you mentioned; it’s not as easy as simply changing a resistor for other chips. Speaking of other chips, I do know for sure that the 603 does not support half speed multipliers where the 603e does.

    How about this: old hard drive sounds emulator?

    Two things: First, I have a number of obscure hard drives I could record if there was any interest, including a quasi-functional NEC 3.5” 105MB unit and a Sony SRD2040 (of Quantum infringement lawsuit and Apple recall for stiction infamy). Second, regarding sound length vs. data transfer speed: what happens if the time it takes to play a sound is longer than the time needed to transfer data? SSDs are markedly faster than spinning disks, especially for seeks (the process that makes the desired sounds) so it’s entirely possible the sound playback/generation will take longer than the actual data access cycle. So: Does the system wait until the sound has completed before moving to the next data transfer task? Does the system queue sound for each access, resulting in the potential for sound generation continuing after data accesses have completed? Does it play random sounds on any access? The answer is probably at least partly dependent on what’s generating the sounds, whether it’s the computer itself, the controller, or an external device monitoring the bus/controller accesses. I’m also interested in how authentic it would sound: anybody who has ever tried to move 10MB to/from a 20MB MiniScribe 8425 in an SE knows it involves at least 30 seconds of sound and fury, whereas an SSD would complete the same task in only a fraction of the time, likely eliciting only a couple peeps from the sound generator (assuming sounds are generated only for the duration of the data access rather than one sound per seek event).

    Bolles finds

    To be fair the only proper 601 you mentioned in your list was on the Turbo 601 where all the others were 601v; the original 601 didn’t exceed 80MHz and Apple never used them at 3:1, only the later >100MHz 601v-based models (the only exception being the 7500/100, running 2:1 on a 50MHz bus).

    Bolles finds

    The 601 and 601v are not directly pin compatible because of voltage differences. The fastest 601 you could swap in would be 80MHz. Also the 601 may not support 1/3 bus ratio so an overclock to 100MHz on a 33MHz bus may not be possible.

    PC Compatibility Card - PM 4400 PCI slot 1 or 2

    That pad is to protect the exposed die from uneven pressure in case of improper heatsink installation, not for any thermal management. It's not strictly necessary unless you're klutzy or careless. Id put the PC Compatibility Card in the top slot, then get the 4MB VRAM card for the onboard video and the internal GIMO cable. I would also get one of the clone Tanzania 3-slot PCI cards instead of the stock 2 PCI/1 CS card.

    Apple PHX 100

    You mean this, copied straight from the 5200/6200 Dev Note: Yes it says the 68040 bus is 32 bits "wde", and that L2 cache is attached to the 603 bus and helps to "optomize" system performance. Typos and omissions aren't exactly foreign to these Dev Notes. Note my previous observation that there are exactly zero references to the system bus speed, only to processor internal clock and the 16MHz of the CS/LC PDS slots. It doesn't mention system RAM speed either. Did you read previously where I noted that there existed ZERO 603 processors that could run at 1:1 processor:board speed exceeding 66MHz? I linked the 603 UM. It's not that many pages. That alone should be enough of a clue that anything physically external to the 75MHz processor on a 6200 is running at a lower rate, specifically no greater than half of that (which is 37.5, if you're curious). Or maybe the fact that absolutely no Apple support chips produced in 1995 ran faster than about 50MHz, including Capella? Even if it did, there's the fact that neither the L2 chips or Capella changed with the increase to 100 or 120MHz 603e models. If the faster 603e chips ran their external L2 caches at 100 or 120MHz, why did they use exactly the same L2 cache modules from the 75MHz models? Were they somehow upward compatible with a >25% increase? And why did the faster 603e require a heatsink while Capella, now supposedly also running at 100 or 120MHz, didn't? It's because everything outside of the processor on the new models ran at 40MHz while the 603e ran at a multiple of that (2.5 or 3x) internally. Again, according to the documents from Motorola, there were exactly zero 603 or 603e chips that could exceed a 66MHz bus. Go boot a 52/62/53/63xx, run TattleTech/Newer Gauge or Clockometer/Speedometer/Metronome/whatever and tell me what speed it has the system bus and L2 caches. I guarantee it's 37.5 on the 75MHz models and 40 on the 100/120MHz models. Anyway going through my cache of Dev Notes, I don't have one for the 6300, only the 5260 which is basically the same as far as the board is concerned: it runs the 100MHz 603e instead of the 75MHz 603. I don't have any Dev Notes for any machines with the 120MHz 603e or the latest variants with soldered ROM and vacant L2 cache slots. These things don't have the greatest documentation. I'll concede the CS/LC PDS thing as being a rare perfect storm, if it happens at all; I've never tried it because I have few non-Ethernet LC PDS cards. However, as you noted with the CS Ethernet and IIe card where "Apple says it won't work", I'll assume this is because the CS and LC PDS slot share the same 030 bus and only one can be active at a time. So basically choose one and forget the other (excepting CS modems, which are basically serial pass-through devices not on the 030 bus). Not that there were a ton of options outside of networking anyway.

    PB 2400c USB: cannot boot with card installed

    I generally remove cards on boot anyway, unless they're used for booting (which USB isn't on something that old). The 2400 (and 3400 on which it's based) is not supposed to have CardBus so there are probably some software routines that don't run properly. I don't consider it a problem big enough to find a solution.

    Boxed 4400/200

    Yeah I guess their marketing team decided that Vimage had brand recognition outside of Japan or something, so Interware used that name on their processor upgrades sold overseas (previously it was specifically applied to their video cards, while their processor upgrades were sold under the Booster name). I prefer OS 8.6 to 8.1 for a number of reasons, but the main reason to use it here is the FW/USB combo card which doesn't have support on 8.1.

    Dual 600MHz Cube

    The only chip that is pin-compatible with the 7400/7410 is the original 750, and that would be a step backward. All of the later 74xx series chips are different either because they use on-die L2 cache or they have on-die L2 plus external L3 cache; in either case the pins are different not only from each other, but from the preceding 7400 models. Also, as mentioned, the later chips have a different and greater power requirement that would need addressed even if you could physically mount them. So it looks like the maximum speed with a 7410 is going to be about 600MHz.
