I received a TRS-80 Model 4 from Erik Klein (thanks Erik!) that needs a
little care. The machine hasn't been opened in 25 years, and it's a bit
grimy. The keyboard barely works, and the drives probably need
disassembly and cleaning too.
I have the Sams Computerfacts for the Model 3, which should be close
enough to the Model 4 for the type of work I'm going to be doing. Any
words of advise before I crack the case open and void the warranty?
I plan on taking lots of pictures as I go to avoid forgetting how things
go back together. I'm also going to be cleaning the inside of the
machine as best as I can, keeping well clear of the CRT which I
understand might try to kill me.
