6502 chip

Armstrong, would have loved to have that much processing power, 
when his on board altitude computer was unable to handle the 
landing and he had to take over manualy. The 6502 was mid late
70's processor used in the first Apple and the Apple 2 and 3. 
The moon landing was in 69 pre dating even the Intel 4004 that
came out in the 71 ish time. Neat little processor that with 
a little practice I use to be able to write op codes directly
without using an assempler Relitive jumps were a little pain full
as the offset was limited to 256 bytes.
