If the machine is in good condition, then you could give it some extra life by swapping in a 6400 logic board, which would pep it up very nicely. A 6500 l.b. could do even better, but I am not sure about the compatibility of the power supply.
I had one of these years ago -- worse than yours, in fact, as it was a 5200 -- and it was indeed truly dire as a general purpose machine. The analog board died in the end, and I could not bring myself to have it repaired. That would have been around 1999, when a 6400 logic board upgrade was still a realistic upgrade for "real" use, but the demise of the analog board as well made it too expensive a fix. I was not prepared to put money into it, truth be told, as I thought it such a piece of crap. That 5200 is only of only a couple of my machines that I have happily trashed.
Anyway, after it died, I used an old 68030-based machine as a tie-over for a couple of months, until I went from the 5200 to a used Wallstreet G3 @ 266MHz, and then within a couple of months added a G4 Cube to my toolset. Oh, the raw speed!
