    Macintosh IIsi Oscillator-Replacement Overclock Successes and Fails

    It works, I've done several, however you are now running also the PDS slot at 25MHz, and not all expansion cards are happy with that. Most of them work just fine though. The Interware Booster will for example not work since it would mean trying to run the CPU at 75 Mhz, I have also had some...

    Apple Network Server MacOS based ROMs found

    Yes, unless you hack the flasher tool you're stuck with those chips. I know @dougg3 managed to hack the flasher tool to at read the M29F160FB5AN6F2 chips (those are used for Rominator and similar), but I think @dougg3 idea here was to use socketed chips and then flash them one by one (8 times)...

    Apple Network Server MacOS based ROMs found

    Yes, is the short answer, but it’s a little bit more complicated than that. Essentially the ISP that @zigzagjoe has created does this for the se/30 and Quadras, it even has a reset output that automatically restarts the computer when flash is finished. It uses a RP2040 which you hook up to your...

    Apple Network Server MacOS based ROMs found

    Sure, it was on the other forum :) https://68kmla.org/bb/index.php?threads/power-macintosh-ppc-rom-dimms.48634/ Been looking a little bit in my head to create a flashable dimm for the PPC, but it haven't materialized yet. I think the best way would do something with a RP2350B and the...

    Isn’t this the same type of flashable DIMM found for the early PPCs?

    Announcing BlueSCSI Toolbox – Web Edition

    Yeah, that is what I'm using, but other SSD should also work.

    Announcing BlueSCSI Toolbox – Web Edition

    Interesting, I was probably just lucky, but I have never had any issues installing any SSD drives in my G4 or Cubes. My drives are 2.5" sata SSD from aDATA of 120gb size. The only issue with ssd I have is that my PowerMac G4 does not like flashed PCI SSD-cards (same cards works fine in G3 and...

    Announcing BlueSCSI Toolbox – Web Edition

    For my Cube I used an IDE to SSD interface (from StarTech) and then a regular drive. Have the same in my PowerMac G4, this works great. Like this : https://www.dustin.se/product/5011176108/40-pin-ide-pata-to-sata-adapter-converter I highly doubt a "BlueIDE" would be able to meet the same...

    CayMac LC Style Mean Well PSU Replacement

    Great feedback! Very interesting with that drive, I figure it's an inrush current phenomena, might be possible to add a power resistor to ease that up a little bit. There are of course also a 15W and 20W model of the IRMs for 12V, but they are slightly bigger in size. When dimensioning these...

    Making a replacement Hinge for a 15" Studio Display

    Stumbled upon this thread and wanted to add the files for the 17" display. I made these a bit more than 3 years ago, but if anyone needs them they are here. Mine are also with threaded holes, but you will still need to put a tap through them to clear it out. And I also had same experience with...

    Check if Centris 650 has a fpu or not

    So, I found the issue. It's more of a "feature" than actual bug. I had added support for large (128MB) simms by doing: The change to the RAM sizing code is: A0168 223C 0000 0100 Move.L #$100, D1 Changing that to: A0168 223C 0000 0000 Move.L #0, D1 As per Rob...

    Check if Centris 650 has a fpu or not

    Can you also take a picture of the ROM in the machine with the power on? There are a few LED that give a lot of information.

    Check if Centris 650 has a fpu or not

    Does it chime with the hacked ROM? Are you getting picture? I've been running this ROM in my Q650 for a long time, but not sure if the Centris has like a different gestalt ID or so.
