One of my co-workers has entrusted me with their first computer: an IBM Portable Personal Computer 5155. I don't get to keep it, but I do get to repair it.

In Part 3 of this livestream series, I will be replacing all of the tantalum capacitors to ensure a long and pleasant computing experience. Please don't get mad if I don't do something with this computer, it isn't mine so I'm going to be a bit more careful with it... that also means I'm going to re-assemble it at the end of the stream so that I don't risk losing parts.

Will I get the old tantalum capacitors out without issue? Will this bring back good memories? Will I miss a tantalum capacitor un til after I re-assemble the 5155? You'll have to watch to find out!
