The Apple 1 was a single design, but multiple products
There were multiple incarnations of a particular computer design that would eventually be called the Apple 1:
- Wozniak's prototype boards.
- Schematic plans shared with members of the Homebrew Computer Club.
- Boards fabricated by members of the Homebrew Computer Club, according to Woz's schematics.
- Bare, silkscreened boards to be sold for $40 each.
- Fully-populated boards sold at the Byte Shop for $666 each.
These are different physical manifestations of the same circuit design. By the time #4 and #5 happened, Woz and Jobs had formed a company called Apple Computer, and Woz was already planning the more sophisticated computer that would become the Apple ][. Thus, it was reasonable to put "Apple 1" on its silkscreen.
The Apple 1 began in 1975 as Woz's need for a home terminal:
BYTE: How did you get to the point of designing the Apple I?
Wozniak: I had worked my way up through software using
a terminal on a local time-sharing system. Sometimes I'd call
it from work, but I wanted to do it at home. I eventually designed and built a TV terminal and a modem so I could call
this computer and play games.
Byte magazine, December 1984, p. A68
Woz showed his computer to the Homebrew Computer Club, shared the schematics, and even assisted members in fabricating their own copies:
Steve and I had both been going down to the
(Homebrew Computer) club and giving out schematics for
the computer and the terminal, even going over to peoples
houses and helping them build and test the computers out.
ibid, p. A69
During this period, Woz realized the limitations of this first design:
In 1975 video terminals were designed with shift registers
because there were no cheap RAMs. You'd set up a bunch
of shift registers and keep shifting them around to send text
to the TV screen. So the Apple I was slow. It could type out
60 characters a second -- one character per scan of the TV
screen. My motivation was totally to save chips, not to add
features.
BYTE: Was the Apple I really a full-blown computer?
Wozniak: Yes, but its features were a little bit different than
the Apple II's and other personal computers that followed.
It was slow, and it was text only, but it was a lot faster than
the teletypes we were used to. They could only type 10 characters per second.
ibid, p. A68
In particular, Woz saw a demonstration at the Club that inspired him to create a new computer design that would add color:
At the time, Cromemco had just come out with a board
called the Color Dazzler that did color graphics on S-100 systems. We had also had a demo, at the club, of a minicomputer running a display of a clock on the screen in color. During one of my times at Atari with Steve, I had designed a
little seven-chip circuit to do color on a TV screen and it
worked. So I started working on things that I wanted to add
to the Apple I. I was thinking about clever color circuits and
how to cut the chips down.

As requests for Woz's original design increased, Jobs proposed creating a company to sell professionally-made boards:
BYTE: So how did Apple Computer actually get started?
Wozniak: Steve and I had both been going down to the
(Homebrew Computer) club and giving out schematics for
the computer and the terminal, even going over to peoples
houses and helping them build and test the computers out.
Steve said, "Look, people are interested in what you've got.
Why don't we make a PC board, have it silkscreened so they
know what parts to plug in, and sell it at the club?"
We had about 500 members in the club, and I thought that
maybe 50 people would buy it. It would cost us about $1000
to have the board laid out, and each board would cost us
about $20. So if we sold them for $40 and 50 people bought
them, we'd get our $1000 back. It seemed pretty doubtful.
But Steve said, "Well, yes, but at least for once in our lives
we'll have a company:" So Steve sold his van and I sold my
HP calculator to raise the money to make the PC boards.
Then the Byte Shop asked for fully-built boards:
Right away Steve got a big order from a local computer
store to supply completely built computers. They ordered
something like 100 units at $500 each, to retail at $666. It
was unbelievable -- a $50,000 order. We were in business.

Jobs came up with the "Apple" name:
BYTE: Just to put four or five stories to rest, where did the name Apple
Computer actually come from?
Wozniak: It came out of Steve Jobs's head, and he's a sort
of private person, so I can't say what led up to it. He came
up with an inspiration. He was working from time to time in
the orchards up in Oregon. I thought that it might be because
there were apples in the orchard or maybe just its fructarian
nature. Maybe the word just happened to occur to him. In
any case, we both tried to come up with better names, but
neither one of us could think of anything better after Apple
was mentioned.
ibid, p. A69
Therefore, by the time the silk-screen boards were actually produced, Apple Computer had been formed as a company, and Woz already had plans for an improved computer. It was thus reasonable for them to print "Apple 1" on those boards.
