  1. Why do you initially try to reflow the corroded solder joint? I just start at your step 6 and I haven’t lost a single pad out of hundreds, if not more, since I started doing that. some flux and solder wick to remove the old solder and cap legs and then shine up the pads with ipa.
  2. There is a Mac Classic for sale somewhat local that has a Din 8 (not mini) connector drilled into the back. Any thoughts as to what it might be? Some sort of video upgrade?
  3. I hadn't seen any references to the C programming videos you are doing - that's a great initiative! I had started trying to learn toolbox programming using C on the mac a while ago and put it down but plan to get back into it and will be sure to check these out. Thanks! (And obviously the RAscsi hack is incredible!)
  4. Love it!!! This is a great idea - Even on a color Mac I've never used that label menu. Glad to see someone has finally put it out of its misery!
  5. That's crazy!! Those are the caps I thought were Polymer (or at least the whatever uf the purple one is). I'm like 99% sure that purple cap will say OS-CON on it which when I googled seemed to indicate those were solid polymer caps. It's obviously leaking though so maybe not all that solid!! I've done a few inverters (PB160s, PB145b) and hadn't ever come across leaking caps like that so I had assumed they were in fact Polymer. That being said, I still always replace them and now I'm even more glad that I have.
  6. Most of the inverters I’ve seen in 1xx PBs use those Oscon polymer caps so weird they would leak.
  7. I agree with Fizzbinn. There might be some confusion that the memory being recognized is due to a non 32 bit clean ROM when in fact it’s because Apple cut corners and artificially put a memory ceiling onto the Classic II.
  8. I’m a little bit confused about the right side of the machine. The left looks like it’s all filled with logic board and power supply but the right side seems very hollow. Is the right side designed to store stuff like that floppy drive I think is pictured? How hollow is the unit?
  9. Just a note that this isn't accurate - there are caps in the greyscale displays.
  10. With a $37 BOM before the Pi are the economics there for this versus a SCSI2SD? Are there other advantages beside potential future features like potentially Ethernet?
  11. As noted though the screens do need to be recapped. There are 9 plastic encased electrolytics that 100% for sure are leaking. At lease one of the caps on the inverter is polymer (Oscon) but I usually still replace those as a matter of course.
  12. I thought the issue Steve had noted was just associated with using the floppyemu with th softSp card for Apple iis? Is there another issue? 8bitguy replaced his CPLD as he indicated that per Steve, they can just go bad.
  13. Yes. It's generally only ever three jumpers, one for each bit of a 3 bit address allowing for 0 to 7.
  14. Have you tried booting with extensions off or using extensions manager to see if you can narrow down what hardware is being called at the point in the boot process that it freezes? Have you tried zapping the PRAM?
  15. Is your ribbon in the right position? If you don't have it in front of the head it will do this. It's easy to accidentally place the ribbon behind the head.
