Well... now let's try this:
As I see a CPU gets more valuable as earlier it is - right?
So, now I happen to own a KIM which I belive is the real #1
board. The CPU is a MOS MCS 6502 dated 4675, white ceramic.
As such it is from the very first batch of 6502s, of course
includeing the infamous ROR bug (no, Intel wasn't the first
to sell buggy CPUs :). It ends not just there, but it might
even bee THE first 6502 - or at least the first to be used
in a manufactured computer.
Now this chip might for shure be of some value to collectors,
just if I'd take the CPU out of the board and replace it by
a later, bug free 6502 (which has been done to a lot of CPUs
back then), I'd still have the #1 KIM, in a beliveable and
usable configuration. The classic computer value will still
be the same (*1).
On the other hand, the CPU in it self, although still a quite
early date, and maybe *RARE*, suddenly lost any proof to be
that special, it is even less worth than a NOS version, since
it is unsoldered.
Anybody here to help the chip collectors out of this dilemma ?
Gruss
H.
(*1) I have no idea about a 'value' to assign to this unit,
especialy since the only valid way to do so would be to sell
it ... na, never :) - the same is true for a first series 6502.
