    A couple modded Color Classics

    I think I'm done with these for now: On one I built a 2A@3.3v regulator into the harness. Not my prettiest work, but it's small and unobtrusive and gets the job done. I also cleaned up the various harness cables so it wasn't such a mess and also to improve air flow. It is sitting with a 160MHz Alchemy board with 128MB RAM and a nice double-partitioned (for 7.6.1 and 8.5.1) ATA Fireball hard drive. The floppy drive has been reconditioned and had the mushy orange ejector gear replaced. A nice little unit, responsive and capable of pretty much anything you'd want to use with a ~9" 640x480 screen. The other I tried to install a 225MHz Gazelle board into (without a 3.3v regulator, because it supposedly has one built in to the board), but for some reason it won't play nice with the ATA hard drive. Maybe it actually needs the 3.3v regulator? Every other board I tried in this machine works with the hard drive (and this board works with ATA drives in other chassis), so I just dropped in a 120MHz 53xx board with 64MB RAM and called it good. Its floppy drive was also reconditioned and the harness cables cleaned up. It works well enough, though it would be nice if the stupid L2 cache would work. It's also running a double-partitioned hard drive with 7.6.1 and 8.5.1. I bought an IDE-to-CF adapter to use with one of these but discovered that I don't have any free CF cards. Since I'm only using HFS formatting for maximum software compatibility I didn't really see the use for a huge hard drive anyway. Maybe one day I'll switch it out or instead get an IDE-to-SD adapter; I have stacks of SD cards but the adapters are 2x more expensive.

    Performa 5320: what clock speed?

    The saga continues: I bought a lot of 820-0751-A logic boards online recently and when the box arrived, it had a few surprises: There are two different clock configurations of this board: 100MHz or 120MHz. The boards are unmarked in regard to speed ratings, but apparently they used a color scheme to differentiate: the 100MHz boards have a silver heat spreader, while the 120MHz parts have blue heat spreaders. Also, all of these boards use IBM processors. I attempted to install a L2 cache in a couple of these boards, but either it won't boot (with the IDT SOJ-style chips) or isn't recognized by any profiling utilities (with Motorola PLCC-style chips). Running benchmarks suggests that the L2 cache, when installed but unrecognized, provides no benefit, so either these things had weird special cache modules (that I can find no reference to) or all of my L2 cache modules are dead. Another interesting note: when comparing various examples of the Quadra 630 and derivatives up through the 53/63xx series, there are often significant differences between suppliers of the various chips on the board. For the Valkyrie, it seems the first and primary supplier was Sierra Semiconductor, then a good number of AT&T parts appeared in the later versions, and I have a single late-model board with a Chips-sourced chip. Primetime is usually VLSI or TI in earlier models, with a Samsung version more common in the later models. F108 is usually VLSI, but there are TI parts out there. Capella is usually Fujitsu or occasionally VLSI. I found this the most interesting because I have never seen a Fujitsu-sourced ASIC in a Mac before.
  3. I have three of these boards in various speed grades and all three will chime and then... nothing. No green light, no display, no keyboard activity (it doesn't seem to do the second keyboard light flash). It doesn't matter if there's RAM, cache, or a good PRAM battery installed or not, nor does it matter which chassis they're installed into (I have three different Macs they fit into): they all chime and then sit there blankly until power is removed. Two will respond to a keyboard reset command, the third won't. None will do a PRAM reset from the keyboard. Anybody know what the deal is with these? Is it a common problem? Is there something specific to check? Are schematics available for these? I was planning to use one or two of these in modified Color Classics, but if they're that temperamental I'd probably switch gears and go with a 5400 board; they seem more stable.

    Are you running a SCSI CD burner in your color classic?

    So do these old optical drives. Typically they just develop intermittent problems with reading discs rather than failing completely. I assume this is primarily due to the diminishing output of the laser diode and/or reduced sensitivity of the sensor. Matsushita drives are really bad for that but I've had some success in adjusting some of the pots on the optical block to bring them back into service. Also, loading belts are always a problem after a while.

    Sometimes USB isn't an option. Sometimes you only need to burn a few hundred megs. Sometimes your friend's car still only has a CD changer. They still make cassette tapes, too. I haven't seen new Type IV tapes, Type II are kind of sparse but they're around if you look hard enough, and Type III were crap so they've been out of production since the '80s, but basic Type I tapes are still readily available in a variety of lengths. I guess they're still useful for dictation or cheap and easy recording when fidelity isn't your primary concern.

    Are you running a SCSI CD burner in your color classic?

    Toast or b's Recorder Gold are the only Classic Mac OS burning programs that I know about. I think both are available on the Garden. I have a stack of old SCSI CD-R drives (Sony, Matsushita, Ricoh, and Yamaha, both tray and caddy-loaders) but because of their advanced age I really don't trust them for burning. Plus the 4x Matsushita units and some of the older Yamaha drives constantly run their itty bitty fans, and those things are loud; I put those in external cases so they're only turned on when I need them. The later models (8x or better) only run the fan when there's a disc in the drive, which is an improvement. If you're trying to use CD-RWs (in an RW capable drive, of course), note that high speed discs will not work in these older drives; you need to find the older discs in the 4x range that don't say "High Speed" or whatever on them or the drive won't recognize them.

    Mustang Prototype-5300ce with big 1400 LCD - 3D printable yet?

    The PB 5300 is basically the portable equivalent of a 53/63xx, using recycled parts from the PB 500 series in the same manner the 53xx reuses Quadra 630 parts. On the 53/63xx series, the 030 bus runs at 16MHz on a branch of the 040 bus, which in turn runs at processor bus speed (37.5 or 40MHz). The PB 5300 and 2300 do pretty much the same, though I don't remember the exact specs off hand. I also don't remember exactly how the PB 5300 gets its bus clock; the various crystals spread around the board suggests that it derives bus frequency directly from that 33MHz crystal, unlike other machines like the desktop 53/63xx that use a single crystal and a clock generator chip to send the correct clocks to various devices. I would consider experimenting myself but until I can either replace the processor at the same time or figure out how to change the ratios, it's unlikely a 100MHz processor would boot or be stable when clocked to 120MHz.

    Also, the system bus speed appears to be set by a dedicated 33MHz crystal. I'm curious if you could replace it with a 40MHz part for a nice bump. Keeping the processor at its 3.5x multiplier will also yield a 140MHz processor which would be worth a processor swap even if you couldn't figure out how to increase it further. I'd consider trying this myself but again I don't have a ce on hand, just a couple janky cs units (they'd only get to 120MHz at original 3x multiplier). I don't have any replacement processors either

    Yeah most of the high-end configurations had that video mirroring/2nd display card with dedicated 512k VRAM on it. I find that it's mostly useless unless troubleshooting or running a headless PowerBook for some reason. None of the ce models that I've seen have used BGAs; they've all had QFPs. The 603e was available in QFP form up to 200MHz or thereabouts, so it's not like they would have had to move to a new form just for that 17MHz bump. Also, to use a BGA in place of a QFP in the 5300 would have required extensive board redesign which wouldn't really have been worth the effort. You may want to check yours, though; I'd be happy to be surprised if it is BGA but it would be better for your project if it was a QFP. The Mustang was of course a different animal with a new board, so it's understandable that they would want to use a BGA from the start to save on real estate. defor has a Flickr album with a picture of the Mustang's processor and it appears to be just a 100MHz part, which I'm not sure why they would bother with if they were going for a new model. I mean, why bother to replace an existing 100MHz model with a nearly identical one? Maybe it was just for testing? Another thing to note: most of the 5300c and cs models appear to have 512k of main VRAM implemented in a single chip but there are pads ready for another VRAM chip, which would take you to 1MB. I don't have a ce model with me so I can't tell you if it always has 1MB of VRAM or not, but if it doesn't it should be easy to add another chip.

    Right, so I clicked on the Super5300ce link and apparently you have the same card as I do. Did you ever get the processor swapped over? That thread seems to have died.

    Mustang Prototype-5300ce with big 1400 LCD - 3D printable yet?

    The ce already does 800x600 on its internal display using standard LVDS. If you want anything higher than that (or with more colors) your only option is to attempt to upgrade the built-in VRAM; there's really no way to upgrade the video controller (I'm 90% sure it's a Chips 65k series on an 040 bus). If your plan was to rewire the video out card, it has the same concerns: small VRAM, slow controller, 040 bus, only now it doesn't do LVDS output natively and thus you'd need the controller you mentioned. Maybe someone made a higher res video out card? I have some sort of combo video/Ethernet card for one of mine that I quite like; I think Focus made it.
  12. Every HK-supplied product from this era will suffer from this, from the Cube to iMacs to G4 towers to the SoundSticks. The Apple Pro Speakers (the ones with for the digital audio Macs) seem to use a different, more robust material for the cone reflex, so they may not be HK or they may be a revised part; I used a set of these to replace the rotten speakers for my Cube.

    SE/30 - What card could this be?

    Token Ring is media agnostic, so long as everything in the Ring shares the same media or has appropriate hub equipment to bridge the different media. The DSub connector was probably for an AUI to whatever media you were using. Normally Ethernet cards that have AUIs use DB15 (like a Mac video connector or PC game port). Token Ring is largely useless today due to the use of special hardware and different protocols than Ethernet; you can't use a Token Ring card on an Ethernet network (unless someone built special multi-function cards or something). Plus there's the fact that it hasn't been in development for at least 20 years and no modern network equipment is likely to be Token Ring-aware.

    ADC to DVI adapter Power supply?

    You have the white unit with the power supply inline with the cable? I have a different type of adapter that uses a kind of Y-cable and a Cube power supply (Dr. Bott DVIator). Not that it's likely to help you any, since Cube power supplies are usually kind of scarce, but maybe you'll get lucky and find a set.
  15. Sonnet recommends de-interleaving RAM with their upgrades so you may want to try that. Did it come with software? You may have to run a patch or something specific to the 1GHz card. Also you'll need a good PRAM battery so that it doesn't forget the patch.
