  1. RaSCSI Development Thread

  2. Colour Classic VGA -OUTPUT- mod / add in VGA cable

    I don't think the CC logic will do VGA, pretty sure you need at least a 520 board.
  3. Power Mac 5500 picture problem

    Audible clicking the coincides with screen distortions is usually solved with a recap but it could also be the Fly-back transformer in my experience.
  4. Leaky battery on a Macintosh Classic motherboard

    In my experience, the only board that will survive a battery leak is a Classic board. Here's what you do: 1. De-solder the what's left of the battery holder 2. De-solder all can style caps 3. Clean the area around the battery holder with rubbing alcohol and a tooth brush 4. Apply flux and re-tin ANY corroded solder joints 5. Place the board in the dishwasher without soap 6. Blow out all the ports with compressed air 7. Bake in your over at 170 Fahrenheit for 3 hours 8. Hook it up and see if it will boot If it works you can then recap it and you should have a good solid board! Classic and Classic II boards don't need ANY of those can caps to boot but without them you won't have any sound. Here's replacement parts: https://www.ebay.com/sch/i.html?_sacat=0&_nkw=32.768khz+crystal&_frs=1 https://www.ebay.com/sch/i.html?_odkw=1%2F2+aa+holder&_osacat=0&_from=R40&_trksid=m570.l1313&_nkw=1%2F2+aa+holder&_sacat=0 Good Luck, Josh
  5. SE/30, 7.5.3, and Mac Rom-inator

    You have to boot off of the rominator and modify the 7.5.3 files to work with the rominator: https://www.bigmessowires.com/mac-se30-with-upgraded-rom/
  6. Repairing a Radius 16 Accelerator (Plus)

    That’s correct!
  7. Repairing a Radius 16 Accelerator (Plus)

    Adding more photos of the accelerator as requested by a forum member:
  8. Good Luck! If you want those things out of a LC III you better install the board in an ATX case and rig up an ATX PS.
  9. Macintosh Plus Internal SCSI MOD

    That can be arranged!
  10. Macintosh Plus Internal SCSI MOD

    My final board design is complete and I couldn’t be happier! This setup is perfect for my Brainstorm accelerated board.(The Brainstorm accelerator doesn’t support HD20)
  11. Macintosh Plus Internal SCSI MOD

    To install one solders a header into the back row of pins and then solders my board to the header. Then you solder a diode and a ground wire. Pretty easy! It does not prevent the external connector from working at all, to the Mac plus it’s just another scsi device.

    Another logic board, different pics:
  13. Macintosh Plus Internal SCSI MOD

    I've made a little progress, I need to do one more board revision and this project will be complete. The good news is that I’ve made it possible to fit the adapter in the case by making the board a little longer and using a right angle connector. This allows the cable to exit the back and loop around into system and connect to a SCSI2SD or hard drive. For persons with expert soldering abilities it can be installed without removing the external SCSI connector but I suspect most will want to remove it.
  14. Macintosh Plus Internal SCSI MOD

    I ordered another board but have yet to install it.
  15. My IISI has a supermac 8-24 PDQ and that will do 1024x768.
