Which transistors are used int he KIM-1 and clones?
The LED driver and serial circuit require transistors.
MOS used 2N5371 and 2N5375, in later KIM-1s a wider variety. A question in forum64.de in the Nachbau KIM-1 thread made me look at my KIM-1 retro.hansotten.nl/6502-sbc/kim...

The great thing about the KIM-1 is that if you don’t have an original you can build yourself a clone. Here is a PAL-II you can find on Tindie beside an original.

50 years of KIM-1 and me
retro.hansotten.nl/50-years-of-...
I have collected some KIM-1's over the years. The first KIM-1 in 1978, and now I have nine original KIM-1s, from first edition to Rev A, B, D, E , 2x F, 2xG.
And several reproductions with 6532's as replacements.

One of the very first _affordable_ computers that could be used by hobbyists was the KIM-1 from MOS (later Commodore). The KIM-1 is 50 (!!!!) this month.

Back when computers were new, they required good documentation (sadly this practice has ended for the most part). The KIM-1 had EXCELLENT supporting manuals.
