I don't either.  I have a SYM-1 which is very KIM-like, but with 6532s
(no ROM) rather than 6530s.  I've always kinda wanted a KIM, but not
enough to go trolling on eBay for one.

That's really strange.

Old caps are one issue to deal with, so are crufty sockets.

I got my start on a chicklet-keyboard PET.  It helped that I was a kid
and didn't have sausage-fingers, but at the time, I _liked_ the square
layout - made8-way directional games easy to play.

Nice.  One of my greatest shocks when I got a 32K 2001-N (essentially
the American version of the 3032) was finding out that TIM was in ROM
on rev 2 ROMs.  I quickly tired of entering in programs in hex and
dropped $15 on a blank 2532 to get a better monitor from the local
user group.  Still have that 2001-N and it still has that ROM fitted
in it.  Maybe I should back it up ;-)

Enjoy learning TIM, but if you intend to do much with that machine,
you might consider an add-on monitor with more functionality (like
line-at-a-time assembly and disassembly).
