    SE/30 and Internal CD Drives

    SCSI (50 pin) slot loading drive... hard to find to my mind!

    Yes that's true but it'll be hard to fit inside...

    Should it be recapped?

    I've heard Duos logicboards are timebombs... If one powers it with leaking caps inside -> little hope to make it work again even after recapping! I have a 210 I racapped years ago but... too late (it boots to the gray screen... when it boots!).

    Aiii. Ugly paint!

    More seriously, You could try rubbing alcohol, I use it on dirty macs it doesn't harm, but never use acetone!! It melts plastics!!

    £2000 powerbook 520!!

    A real day dreamer this seller... Maybe the trackpad is gold plated and the keyboard set with diamonds? https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.fr%2Fulk%2Fitm%2F184117474312 Some people really have time to loose...

    Mac IIfx Clock/Time not working

    I can easily find the MMBT3906 and MMBT3904 but the PC74HC132T is quite expensive and I need two of them... Do anyone know a equivalent component?

    Questions to ask when buying a compact Mac on eBay?

    Be careful and require motherboard pics!! A lot of them died cause of Maxell battery exploding inside... and if it's the case, you lose $100!

    Mac IIfx Clock/Time not working

    Had exactely the same problem since I got my IIfx 5 years ago... The first thing I made when I got it was recapping but the problem was still there! This WE I went on the problem to see if there was any broken trace with the power circuit and RTC schematics... but everything was fine... In purple, the traces I tested were all OK! At last resort I decided to pull a RTC chip from an old mac Classic in order to replace the IIfx's one... and... it works, clock is counting!!! What a surprise since I had never seen a RTC fail before! I still have the power off issue (I have to unplug the mac for shutdown), maybe I'll have to replace the Nand gates and the related transistors?

    IIci dead PSU?

    The electrolytic caps inside the PSU don't necessarily need to be replaced but the "X" and "Y" filtering caps can safely be removed... they often explode inside!

    IIci dead PSU?

    When you short pin 9 and 10 you should hear a "click click" sound. It's the relay inside the PSU which toggles power to the secondary AC outlet. The reason why it's clicking is because the PSU isn't "loaded" and safety circuit prevent it from starting for good. On the other hand, if you don't hear this little clicking noise, your PSU may have a problem...
  13. Hi, The good news is that Q700 Logicboard normally doesn't need recapping since there isn't any smd electrolytic capacitor on it! For the PSU it's clear most of them are out of order now . Sadly recapping the PSU is rarely sufficient to bring it back to live... The solution is to replace its internals with an ATX PSU circuit (or make your own and put it inside the original PSU case). Many people have succeeded in doing this! https://www.youtube.com/watch?v=OfjCPkd11c4

    Booting Mac Plus with scsi2sd...

    Thanks everyone for the update, I'll try that later when I'll have time

    Mac Plus & scsi2sd bizarro behavior.

    Apparently, it isn't possible to boot a plus from scsi2sd... (many threads about this in the forum)
