I bought an Atari 1040ST from eBay (the place where I buy the things I later regret™). In true "Wheel of Regrets™" fashion, I tried powering it up without inspecting it, to which it made a blaugh noise and started reeking of fish. A post-mortem analysis shows electrolyte on the board and a blown fuse.
Even after a recap and a swap-out of several key components, the original power supply still has a fault. It seems as if it is going into either short-circuit or over voltage protection mode, as it is making a repeating electrical clicking noise. I'm going to declare the power supply as irreparable (at least until I feel like throwing all the parts still in production at it). Therefore, I have ordered a new power supply for my 1040ST.
Which power supply did I pick? Will it be easy to install in the 1040ST? And will I need to repair anything else? You'll have to watch to find out!

I bought an Apple IIe Clone Motherboard on eBay (the place where I buy the things I later regret™) knowing full well it was an Apple ][ Plus clone motherboard and missing some chips. Yes, COMPUTER was jealous at first, but then COMPUTER realized I needed practice on a similar motherboard before I continue removing sockets, so were good...
Last time I worked on this board, I replaced enough capacitors to satisfy my concern that there wasnt enough capacitance on the board for proper operation. I was able to confirm the original 6502 was working by swapping it into my Apple ][ Plus. I also removed a few sockets that looked like they had too much solder. Still, the board powers up to garbage. I resigned to ponder the schematic.
Tonight, I am going to replace the rest of the capacitors, then I will commence The Desolation of Sockets. I have identified a few components that could prevent the CPU from running code, and I will be removing sockets for those components if they look questionable underneath. Well go from there.
Will I find issues under sockets? Will I get the board to do something by the end of the stream? Youll have to watch to find out!
