KIM-1 serial nos, etc.

  My first KIM-1 (from Computer Components, L.A., CA, in 1977) is
marked much the same as Marvin describes:

  It is a MOS KIM, the component side has etched Rev. A, and beneath
the KIM-1 logo is etched EC - 715. Beneath that is what looks like a
round QC inspection stamp, ?CC 201 ECI in the circle.

  The earliest chip is a NatSemi LM565CN (7340). The 6102s are all
'76, as are the 6502, and both 6530s.

  The solder side has that 'rubber stamp' looking number between the
edge connectors: 3879 [*not* the date] in whitish ink, and to the
right is a partially obscured stamp in black, ending in 15. Near the
top right is another 'QC' stamp, a circle enclosing ACC, 201, ????.
Below this is a partial sqaure stamp, barely readable, with the
letters 'est' visible. Below *that* is a partial triangle stamp, not
legible at all.

  Perhaps this will help others out there in dating KIMs.... I tried
slicing into the card to count the rings, but the results were
inconclusive.

  Cheers

John
