Along with my vintage computer tinkering I also have a penchant for vintage cars.. specifically Porsche. This recent purchase goes with my recently restored 1970 911. Yes, it plugs directly into the cigarette lighter socket! I'm yet to try it out, but will definitely be taking it along to the...

Nothing to do with me - just saw this on Indiegogo and thought it might interest some here. I signed up for a pack just for giggles: https://igg.me/at/shargeekretro35/emal/29382073 (Mods feel free to delete if not appropriate)

Does anyone have a schematic for the "Apple Singapore" PSU used in some SE/30's? I've found the Sony one, but can't seem to find the Apple Singapore one. My PSU was very leaky, so I've recapped it but its voltages are still about half what they should be. There's a 47K resistor that measures...

I received a Classic II with pretty classic(!) checkerboard display. Reseated ROM and RAM, same result. Recapped logic board, same result. Recapped analog board, same result. It shows checkerboard with or without ROM chips (Rev B so two ROM chips) - not sure if that's a pointer to the ROMs being...

Apart from removing the speaker is there anything else that should be removed before I give the Classic II A/B a bath?

I have two SE/30's here that I'm restoring (recapping boards currently). Unfortunately one of the CRT's has a couple of physical chips in it - looks like it was whacked with a screwdriver or something. Otherwise it's OK. The other is externally OK, but when powered up there's a couple of pure...

I switched to Amtech flux not long ago, so was very interested in Bruce's recent video's on the whole fluxgate shenanigans... and was surprised today that when my NC-559-V2-TF delivery arrived Amtech had included a free sample tube of Sample #88. I was literally in the middle of removing the...

I have a SE/30 here that someone man-handled rather badly in its past and broke the clips (ie both ends) of the ROM SIMM holder. They had then used supaglue (cyanoacrylate) to hold it all together. The glue has aged and cracked so the SIMM doesn't mate correctly now. Other than replacing the...

Are there any differences between A/B's delivered to US vs international? ie in the same way as there are with 128K's etc..? I'm assuming any differences are within the PSU itself..
