  1. Visually check the capacitors on the 1.4 GHz G4 CPU. If the top of the caps are bulging or have brown/black residue, you'll need to replace the caps.
  2. FYI the SuperMac C500 is very similar to the Performa 6360 and about the same size. The 6360 has 1 CSII slot and 1 PCI slot, while the C500 has 2 PCI slots. You could install a 10 Mbit Ethernet card and a 2 port USB 1.1 card n the C500.

    68K (no Mac) Designs OK?

    cbmeeks, I'd recognize that username anywhere! I've been a long-time user of the Parallax Propeller also. Instead of developing with the 68K, have you considered the MiSTer FPGA project? MiSTer emulates a large number of systems in hardware, including the Macintosh, Amiga, Atari ST, etc. Some links you might want to explore SmokeMonster lon.tv
  4. The Performa 6360 was a good machine for running OS7 thru 8.6. It is simple to upgrade. Years ago, I added a G3 220 MHz card and a 10 MB PCI ethernet card to this machine. If the machine still boots, I think it's worth the money. Note you can no longer buy the 4.5V Alkaline PRAM battery for this machine. It's simple to splice the original PRAM battery connector to a 3 AA or 3 AAA battery pack as a replacement.

    Battery clamshell iBook

    Newegg is selling a new iBook replacement battery M7426 for $60 from Powerwarehouse https://www.newegg.com/p/16J-002H-06F55?item=9SIA3771177152 There are no reviews of this battery or any items from Powerwarehouse in Las Vegas http://www.powerwarehouse.com/ Has anyone bought anything from this supplier?

    Full 68040 for Quadra 605

    The power supply fan on my 660AV was making lots of noise. I opened the power supply case (3 screws) and attached a new: 80 x 80 x 20 mm, axial, ball bearing fan, 12V DC. I bought an NBM brand fan from www.mouser.com for just under $10. It's very quiet - no resistor needed. The 660AV is the same size as the 610, and I'm guessing the power supply shares the same size fan.

    Centris 660AV doesn't boot from HD

    I ordered tantalum capacitors today to replace the leaking electrolytic's. The 660AV required (11) 47 uF, 16V, size 2412 (inches) and (2) 10 uF, 16V, size 1206 (inches). The fan on the power supply was also making lots of noise, so I ordered a 80 x 80 x 20 mm, axial, ball bearing fan, 12V DC

    My quest to see video output

    I believe NS stands for Not Supported

    RaSCSI Development Thread

    Inertialcomputing has a good point. A Raspberry Pi 3 B+ costs $35. Figure $25 to order the RaSCSI board and parts and you're already matched the cost of the SCSI2SD V5.1, which is $59.99. Then you'll need to develop the software to use RaSCSI.

    Problem with Power Mac floppy drive

    I've always used a cleaning disk that looks like a floppy, and you wet with cleaning solution (IPA and water).

    Problem with Power Mac floppy drive

    Were you using 800K disks or 1.4 MB disks? I think it's more difficult for Macs to initialize 800K disks due to the variable disk speed per track. 1.4 MB disks are initialized at a constant RPM on Macs and PC's.
  12. Opened the case, pulled both video cards which looked clean and undamaged. Temporarily connected the monitor to the built-in video port with a switchless Mac-VGA adapter and was able to use the computer at 640x480, 800x600 and 1024x768. Plugged both video cards in and everything now works when connected to the video cards??? I suspect some type of extension conflict when running Quake - the 3Dfx card conflicting with the 3D acceleration on the iXMicro card.
  13. I'm using my SuperMac600 with G3/220 upgrade, iXMicro TwinTurbo 128-3D and a Voodoo 2 1000 card. I ran Quake 1 in 3Dfx mode today at 800 x 600 - ran fine. I quit the game and the screen went blank. I had to power off. I've since tried rebooting a few times and confirmed the only resolutions that work are 640 x 480 at 60 Hz and 1024 x 768 at 70 Hz. Anything else results in a blank screen, which switch the monitor into standby mode. The LCD monitor is about 10 years old and has VGA and DVI connectors. The Mac is connected to VGA. For the past 2 weeks, I was able to switch between 640 x 480, 800 x 600 and 1024 x 748 at multiple refresh rates without a problem. There screen wiggled at a few resolutions, but it's stable at 1024 x 768 at 70 Hz. I've disabled the 4 3Dfx extensions and removed the Voodoo 2 card, and zapped the PRAM once. I still am unable to switch to anything but 640 x 480 or 1024 x 768. On startup, I must disconnect the monitor power cable and reconnect before I can a picture - so it appears the VGA sense is not working. Any ideas?

    Building your own case

    Building a PC case from scratch is big task. Years ago, extruded aluminum cases were very popular. There are a few companies building these cases such as Protocase Another alternative is to pick a PC case from Newegg and fabricate the custom brackets to hold components. I think this is the quicker approach.
  15. Has anyone had success recapping a Giga Designs G4 upgrade? My 1.4 GHz G4 upgade had leaking capacitors after about 7 years, so I pulled it and put it on the shelf.
