    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).
  8. Franklinstein

    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.

    PowerBook 2400c with goodies

    I bought this lot because it included very uncommon accessories: the fabled Yu-Plan keyboards. Years ago I heard tell of a green variant of this keyboard but almost never see reference to it anywhere, let alone one available for sale, even though they're US-standard layout. Mine are not green, but apparently there were at least two options available: a black version and a clear version. The computer itself is in excellent shape (and has been upgraded to a 320MHz G3 and 112MB of RAM) and has the black one installed, leaving a clear one for me to install on a different machine. Also included were two extra displays and the guts of another mostly stock 2400c/180 (no idea where the rest of it went), two floppy drives, a few non-Apple accessories, and the PowerBook 2400c Perfect Guide, a Japanese book detailing the development history of the 2400 series and cataloging all of the accessories and popular modifications available for it.

    Apple PHX 100

    Anyone ever hear of one of these? They're essentially a 6200/75 with just the Apple logo and "PHX 100" in the sticker on the front; it doesn't say Macintosh or Performa or anything on it. Cursory searches only turn up a few hits with no real info. I thought maybe it's part of an early production run or sold as a special kit that never really got public attention, like a specialized corporate or educational order.
  11. So I was browsing auctions and I come across a non-functioning SE/30. 'Great,' I think, 'I need one to fill one of those neat-o clear cases that I ordered.' As I looked at it, I noticed a mystery connector on the back. I thought it was a standard Ethernet card of the era with a D15 AUI connector, but usually those lack the screw threads and are off-center, and/or also include a standard Ethernet connector such as RJ45 or BNC. The only other thought I have is that it's possibly a Micron Xceed of some variety. Apparently someone else noticed this too because they kept driving the price up on it. I'm hoping it's the Xceed, because otherwise I paid about $250 for a generic SE/30 with a random networking card. I'll find out in a few days what it actually is.

    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.
  13. I have seen several references that supposedly the 55/65xx Gazelle boards have an onboard 3.3v regulator which allows them to be installed into an older chassis (Quadra 630, Performa 588, 52/62/53/63xx and similar machines) without supplying 3.3v from the power supply like the Alchemy boards (from 54/64xx machines) require. However, upon trying this, I have had no luck: the boards either refuse to boot, or something doesn't work properly; for me they'll only work in machines where they're supplied 3.3v from the power supply. I have tried a couple different Gazelle boards in a few different non-3.3v chassis and had the same results: no boot, or weird problems with disk access or something that disappears when these boards are used in a proper 3.3v chassis or the original boards are reinstalled. Does anyone have experience of installing a Gazelle board into an older (pre-54/64xx/6360) chassis without modification? Or is this just a misconception?

    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

    I picked this up a couple months ago but haven't finished it until now. Thanks to @jessenator I was able to get the missing hard drive carrier. Though not commonly sold in Asia, this is a proper 4400 instead of a 7220. It is badged as a "Performa Package" computer, specifically configured as a "Private Series Graphic Model," bundled with a CS modem and a number of basic graphics programs. Unfortunately, though it's boxed, the outer box is a little tattered and the larger of the two interior boxes with the keyboard and mouse are missing, as are all software disks other than the Mac OS 8 CD. As a consolation, though, it did come with a surprise: a 240MHz L2 G3 upgrade from none other than Japan's favorite producer of Mac upgrades, Interware! Fortunately the G3 upgrade works with generic PowerLogix drivers. I have upgraded it to 64MB RAM, a 10/100 Ethernet card, a USB/FW combo card, and an 8GB Fireball CX, all running with Mac OS 8.6.

    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.

    Apple PHX 100

    Actually, nowhere in that entire Dev Note does it mention system bus speed, so I can understand where there may be some confusion because of this omission; totally Apple's fault here. This is amended in the later 6300's Dev Note (again, the guy's using the 6200's Dev Note to talk about the 6300) but for reference, the 52/62xx uses a 37.5MHz system bus. This bus clock, provided by a single oscillator and central clock generator chip, is used by the processor for its external transactions (internally it is clocked at 2x bus), and it is also the base clock for Capella and F108 and by extension the L2 cache and system RAM. The clock generator chip provides Primetime with a separate 16MHz clock to run the CS/LC PDS slots, in addition to various other clock frequencies used throughout the system. According to Motorola's user manual for the 603, this is a non-standard and unsupported configuration: the 603 is designed to only run at 1, 2, 3, or 4x bus speed, with a variety of supported bus speeds. However, 37.5 is not one of them; the 75MHz part is designed to be run at 3x a 25MHz bus. while the fastest 1:1 speed available for the 603 is 66MHz. In addition, no Apple support chips in existence at that time could operate beyond 50MHz, let alone up to 66MHz. If they did, don't you think the 9500 would operate at the same speed? Why would their flagship have slower parts than their cheapest machine? Anyway the later 53/63xx is the same except it has a standard 40MHz system bus and now the 603e supports half multipliers, which is how we get 100MHz clocks from a 40MHz base (40x2.5). The rest of the clocks and Primetime's operation are still the same.

    Apple PHX 100

    Small correction regarding full-speed external caches: It could technically be argued that the Pentium Pro uses an external cache, because the cache and CPU are built individually on two separate dies, but I contend that it doesn't: this cache is built in the same process as the CPU and the two are ultimately bonded together in the same processor module. They are intertwined to such a degree that any error in bonding or in either die rendered the entire module as scrap; it couldn't be reworked, unlike a faulty memory module mounted externally. Thus, I define the PPro's cache as internal. The Slot 2 Pentium II and III Xeons used a similar approach: the CPU and cache modules are both built on the same process as the CPU but this time all of the chips are attached to a carrier board on a special full-speed cache bus. These are proper external caches running at full processor speed, but nothing else in the system is on this bus or runs at this speed except the L2 cache; everything else is accessed by the 100MHz FSB (the later 133MHz FSB PIII Xeons use small on-die L2 caches, negating the argument and ultimately the need for a slot-based processor). Regardless, both processors were targeted at the maximum performance money-is-no-object end of the IT field and both ended up in a variety of Top 500 Supercomputers (such as Sandia's ASCI Red) while the 603 was used in zero, so I wasn't totally inaccurate.

    Apple PHX 100

    Try running a 68k version of MacBench on the 6100 and original 62xx for comparison. The only valid complaint against these machines is that 68k emulation suffered on the 6200 compared to its contemporaries or successor models, and if MB4 is a fat binary or PPC native you won't not notice the effect with a native PPC comparison with the 6100. Nothing outside of supercomputers ran external cache at CPU speed, ever, at least not once CPU speed started to decouple from bus speeds in 1990-something. No way Apple was going to pay for 100MHz SRAMs for a bargain basement computer. If they could even get 100+MHz SRAMs in 1995, they would have put them in the 9500. Guess what? They didn't: the 9500 ran its L2 between 40 and 50MHz depending on processor bus speed. All Apple L2 caches ran at logic board bus speed until the 9600/300 and 350, which had specially designed processor cards that ran the onboard L2 cache at 100MHz (while ignoring the slower logic board cache), which is still far less than the 300/350MHz of the processor clock. Then of course there were the G3s and G4s with backside caches, and those never ran faster than 50% of clock speed, usually less. The whole point and largest benefit of an L2 cache is to have low-overhead SRAM memory (read: no refresh cycles required) available directly to the processor without having to go through/wait for other chips or narrower buses to get there. The 603 processor can only talk to external devices including L2 cache at logic board bus speeds, especially since not only is L2 directly on the 60x bus in these machines, but so is the ROM and Capella, and I guarantee none of those are capable of 100MHz operation. As for a bottleneck between CS and LC PDS? I never said this was an exclusive problem for the 6200; it affects anything with Primetime including the Q630 and LC 575. Two networking cards could be problematic, if it was even possible to use legacy Mac OS simultaneously on two different domains or network types. Or CS Ethernet and a PDS video card. Or on the 575, CS Ethernet and a IIe card. It's not likely a problem anyone would encounter often, but there's the potential for degradation if both slots were active simultaneously, especially since they're both only 16MHz slots that may share the same '030 bus (the dev note isn't terribly clear if it's two '030 buses or one shared) and the Primetime has other things to do in addition to managing both expansion slots. My point was that there were a few errors or omissions in the guy's page, not that every word he typed was wrong; its still better than the LEM BS.
  22. If you notice from the above diagram, all of the boards referenced are PCI-based, both Alchemy (EDO boards, 3.3v always required from harness) and Gazelle (225MHz+ boards, 3.3v in question). Since both types of boards work in the same chassis, the harness must always supply 3.3v to the logic board. This suggests that the Gazelle boards do require 3.3v, or at least expect it to be supplied whether it's used or not. As for harness part numbers, there may be more than one: the harness itself is physically identical to that originally built for the Q630, the only difference being power wiring and possibly cable lengths to suit different cases through the years. So there could be both a mold part number and a wiring loom part number printed/molded onto the part, both of which may be different from the actual Apple part number. The '90s were a confusing time at Apple. While i do have the other harnesses handy, I don't have a 55/65xx to compare to. Maybe I can look at the TAM if i can see the harness from the back without disassembling it.
  23. Im really only interested because I'd like to speed bump my other MPC-LX200 from its 6300-based board to a 55/6500-based board without modifying the harness. I tried directly swapping it but after powering up there was no chime and an acrid smell causing me to immediately abort that experiment. Restoring the original 6300 board to the MPC resulted in it booting just fine, while the 5500 board booted up when it was installed in a 5400 chassis. This isn't the first time I've experienced failure doing this sort of swap though, hence the question of whether anyone has verified success doing it.
  24. I think it's more of a thing in the mod community, specifically with those building a Power Color Classic. It's easier to build a PCC without a 3.3v power supply for PCI-based boards, but supposedly some people were able to install a 55/6500 board without the 3.3v supply because it's supposed to have an onboard 3.3v VRM that operates from either the existing 5v or 12v lines. If that was the case, though, why do 55/6500 harnesses supply 3.3v to the board? Maybe the TAM board has one since apparently its big external power unit doesn't supply 3.3v, but I'm more inclined to believe that its 3.3v power supply is inside the main body, not on the logic board.
