    Macintosh II Battery Holder Board

    I may but I won't know for about a week. I'll pm you or find the thread if I need one. Still $23?
  5. Does anyone have one of the battery holder boards described in this document? I'd like to recreate it for my unit. http://tim.id.au/laptops/apple/legacy/macintosh_ii.iix.iifx.pdf

    Fitting a SCSI2SD in a 68k Mac

    It sounds like your running the SMI from the share. If you copy it to a HFS formatted drive it will work.

    SE/30 Restoration Fun

    A little IPA will clean that off. It's common for those to get sticky. In theory you'll want to reaply some dielectric grease or paint around the edge to prevent arcing.

    SE/30 Jailhouse vertical bars and other issues

    https://www.digikey.com/product-detail/en/adam-tech/PLCC-44-AT-SMT/2057-PLCC-44-AT-SMT-ND/9829298 Or any friendly electronics supplier. Count the pins and slap that number on the end of PLCC- and you'll likely find a socket.

    Resurrecting dead Macintosh Portable

    Make sure the terminals are not bent down from the weight of the battery. This was a common problem in the day.

    Wire or if it's small enough you may be able to bridge with just solder. The. If you have some put a little solder mask back on it. Also I'd you want to save your chip more heat get a socket for that chip solder that on the drop the chip inside.

    Homebrew PRAM Batteries

    I like this idea. PCBWay has some information about edge plating on their website. https://www.pcbway.com/pcb_prototype/PCB_Sideplating.html I went a slightly different way and made a battery holder replacement. Technically OSHPark doesn't do castellations but it works fine for the prototype need. https://oshpark.com/shared_projects/rO2dGa2h
  13. Mine were the following model numbers. Both were made in Singapore. Classic II (Oct 1991) 630-0525 Classic (Nov 1991) 860-0395 For the most part the caps were the same. I ordered double of what was in my CII but when I went to do the Classic I found I was missing 2 caps that were different. So they are pretty close. Parts list I used. https://docs.google.com/spreadsheets/d/e/2PACX-1vSV2LyGPEhFxpr9oA6FZ2DG7m42-P6yyeyOlBUpjrZJ2qcMCRyWYQzCNh56eypgUVyW4OP-M_NmQE2-/pubhtml#
  14. My CI and CII were slightly different.
