  1. @LaPorta the attached PDF is one of my favorite things memguide.pdf
  2. That appears to be the case. Most of the Sonnet, NewerTechnologies, Powerlogix cards meant for PCI Power Macs work in the broad range of Catalyst Power Computing machines. In one of the threads I've posted in/created user trag articulated the differences for their native CPU cards not being cross compatible, but I think the upgrade makers found ways around the differences to ensure a more universal product (see: early Sonnet Crescendo L2 revision madness for comparison ) As Franklinstein mentioned, yes. The 7200/8200 was an odd duck and the only Apple product to need this soluti
  3. This post shows the MicroMac IIcx adapter for the Carrera Might be a bit of unobtanium these days...
  4. Got around to outlining the caps in the Delta SMP 120EB PSU. Had to add a couple colors to the list of circles, as there are several capacitance-matching caps that have different voltage ratings, and because of pedantry due diligence I included everything as indicated in the original equipment. Also, bear in mind this PSU might have copious amounts of (erratically placed) dry silicone adhesive, which can be tricky to get around. For the to J connectors on the main board (one to the fan, the other to the mains PCB), I used an Xacto knife and some IPA which somewhat softened it, but I had to tak
  5. Using an adapted CF card (for most adapters) is not like using an intermediary device, (e.g. SCSI2SD, MacSD, et al.) but is just a blank medium awaiting formatting: AFAIK, CF and IDE is pin compatible, and the adapter really only serves as passive adapter and in cases of PC use, selects slave/master. (Though mine has a voltage selector as well...) Mine is dead simple, with just a slot for the card, a floppy-style power connector, and then maybe a bit of voltage regulation. No PALs/GALs, or any other logic happening on the board: Well, OP, your mileage may vary, but I didn't h
  6. I am almost in the same boat. My caddy-load is still reading discs ...sometimes, but I finally found this old page I'd seen a while back w/re: diagnosis and repair: http://www.asterontech.com/Asterontech/next_cdrom_refurb.html which is somewhat useful, but only for the AppleCD150.. Our Centris models have the AppleCD 300 (2x), which has a different logic board, but would be a similar repair job. I suppose it wouldn't be too difficult to decode the capacitance numbers and order replacements. Who knows, they may even be the same values. Here's mine. It wasn't hard to get to. Be sure to disconnec
  7. I think that was me (recently I think anyway). Yes, he's still around, as far as I know and that contact email on the site should be up to date! Not sure what shipping would be to JP. He was the source for the through-hole crystals/oscillators, as Mouser and DigiKey are perpetually out of the 66.666 or whatever for 33 MHz operation. Haven't seen any on ebay (while I was looking months ago now). Your mileage may vary, as they say, but I could not get stable operation above 33 MHz, even with a fully-qualified MC68040RC40 CPU replacing the stock 25 MHz chip. From what I've
  8. Yeah, that's the HDI-45 connector for the AudioVision monitors The APPLE specific video card should have the standard DA-15 "Macintosh" video connector on it, from what I've been able to see: Bummer Well, if there's a tray load CD bezel in there, I'd be interested in that. Maybe I'll retrobrite it, IDK.
  9. I'd be interested if any of the 7100s' chassis plastics are in good shape, especially if there's a tray-load CD bezel in the mix. If any of the case plastics are un-yellowed I'd be interested, generally. I want to say @Cory5412 was looking for the HPV/PDS video cards with socketed VRAM, but if I'm wrong, apologies for the tag, Cory. According to the Apple memguide the "standard" card is the socketed VRAM version, and the higher, AV card is soldered. Also, if any of the 7200s are the 120 MHz versions, those might be worth saving, generally.
  10. Alright, I think I've solved the stacking issue: Above is R3. R2 had some issues with it actually grabbing the ceramic of the CPU below it when it snapped into place. One last iteration test I want to make is to see if it's better putting the larger feet on the bottom. Both were "single" holders to save PLA and time. From there, I may end up adding a floor, maybe not solid, but something to prevent pin damage during handling. I mean, depth isn't an issue, there's enough clearance for the pins, but at least putting in an "X" or something for a floor , or maybe covering the pins,
  11. Well, some refinement is in order: I have some weird trapezoidal action happening on the bottom feet, which I suppose could be a nozzle height issue. Tried to slide the feet onto the corresponding notch on the top and the foot just snapped off.
  12. I went to go download a 68040 storage tray, but the model is now gone from Thingiverse So, I decided to start another one, based on a tiny thumbnail of the image: Measured one of my CPUs and have it a smidge of wiggle room, which proved to be just enough: Printed this first draft to even make sure a 68040 will fit in it properly: Seems to work: There's a pleasant small snapping into place for a decent hold. I'll need to print another one and possibly refine the nested legs so they can stack/act like a lid, just in c
  13. MacBench will certainly give you a readout of your Mac's hardware. TechTool is another you could try. I know this was part of SpeedDoubler (I would disable it when I installed the whole suite), but it very well could be a standalone control panel as well. I want to say Norton Utilities also had something like that as part of Speed Disk. IIRC the standalone control panel is called "activity light" ot something along those lines. Might be a good term to search. For your DOS card software, you can find every version, and lots of other useful tidbits, on the Apple Legacy
  14. Bummer about the 610. Seems this form factor us reaching its halflife of sorts, what with the problems posted so specifically about this board. Any luck testing the QuadDoubler in another machine? Edit :Ha! Simulpost Or so I thought. Oh well. Nice numbers!
  15. you have no choice now @quinterro, you have to make this vHack a reality
