I wonder if anybody here has the *exact* months of introduction of the
three first *real* home computers introduced in 1977:
a) the Apple II
b) the Tandy TRS-80
c) the Commodore Pet
I need them for a book on collecting home computers I am researching
for.
Thank you
enrico

The TRS-80 was announced _and deliveries began_ -- no announcement was
made until 5,000 had been manufactured -- on 3 August 1977. The Model
II premiered two years later to the day.

Okay, all sources for the Apple II seem to agree that it was introduced in
April, but what date? From memory I would've said April 17th. I decided
to confirm this with a quick web search and came up with two dates!
http://www.research.apple.com/extras/history/
puts the date at April 20, 1977 while
http://www.kelleyad.com/histry.htm
puts the date at April 17, 1977. Both of these sources have the
credentials to be accurate. Which date was it? Surely someone here
knows.

Well... the most direct (and obvious B^} ) way is from the name plate. If
it does not say "plus" in green letters, it is (or was) not.
But more correctly, (AIR) the Apple II was equipped with the Integer BASIC
roms, and the II Plus with Applesoft BASIC roms.
To add to the confusion, you can look at the logic board to the left of the
RAM array, and if there are jumper blocks marked (in some combinations)
"4K", "16K", then you also have an earlier revision motherboard (and
more
likely a II than a Plus).
