I started noticing articles saying that a new, superior-sounding microprocessor was going to be introduced soon at a show, WESCON, in San Francisco. It especially caught my attention that this new microprocessor—the 6502 from MOS Technologies in Pennsylvania—would be pin-for-pin compatible with, electrically the same as, the Motorola 6800 I had drafted my design around. That meant I could just pop it in without any redesigning at all.

The next thing I heard was that it was going to be sold over the counter at MOS Technologies’ booth at WESCON. The fact that this chip was so easy to get is how it ended up being the microprocessor for the Apple I.

And the best part is they cost half ($20) of what the Motorola chip would have cost me through the HP deal.

WESCON, on June 16–18, 1975, was being held in San Francisco’s famous Cow Palace. A bunch of us drove up there and I waited in line in front of MOS Technologies’ table, where a guy named Chuck Peddle was peddling the chips.

Right on the spot I bought a few for $20 each, plus a $5 manual.

Now I had all the parts I needed to start constructing the computer.
