      Just think, having a Quadra 950 in 1992 would be like having a Mac Pro today… except with more slots, more expandability, and on-board SCSI!

      PowerMac G5 Power Cord

      By RC14 · Posted

      This is likely a very dumb question, but I got a PowerMac G5 without a power cord and was wondering if I could use any power cord with it (I have a couple of generic power cords that fit).  Is there anything special about the apple power cord?

      how to remove cpu from Quadra 840 AV

      By Unknown_K · Posted

      I have a special pry bar that came with a 68040-50 upgrade for my Q950. Very strong flat thin metal slightly curved at the end with teeth that fit in between the pins so it is easy to pop a CPU out without bending a pin.

      iMac G4 won't eject CD/DVD drive!

      By jamie marchant · Posted

      It could be the IDE cable I would think it would be the drive's power cable. Is they a manual eject?

      SE/30 video redraw problem

      By Bolle · Posted

      Check the CPU address lines to the muxes UA8-UD8. Most of the time one of them is broken.

      SE/30 video redraw problem

      By Y030 · Posted

      Thanks guys very helpful. I traced D24-D31 back to the ROM and PDS slot, everything fine there. Also fine were RA0-8 and the other lines RAS/CAS, etc back to the PAL ICs.   Were there any others I should check?   Unless there is something else - then I guess either the 253 mux’s or a bad PAL. Are PAL ICs known to die? Long shot but there a reliable source for replacements? seems unlikely 30+ years later anyone Is burning fresh ones...   Further info, my board is p/n 820-0260-10. It looks like an early revision as it has a factory cut trace to UI6.   PALs are marked: UE6 341-0637-A 918NNDKB UE7 341-0688-A 918YZLAB UG6 341-0635-A 921ZIMOB UG7 341-0633-A 918NLTJB UI6 341-0665-A 917NJFCB
