Apple II/IIplus production dates

I would agree with Michael J. Mahon's post on Apple II production. The
transition from Apple II to IIplus has been a slow and steady one,
regulated by the market. Both models were awailable in the price list
at least until spring 1981 !!, from 1980 on fewer and fewer standard
Apple IIs were sold.
The difference between the two were only the ROMs, name badge and
serial number sticker on the underside.

The other thing is the technical evolution of the II (power supplies,
main boards, keyboards, manuals etc.) The technical evolution was not
limited to the Apple II or IIplus e.g. once Apple used the Rev. 07
mail logic board they used it on both models.

I am trying to collect date on this for a while now - I have a
database of about 100 computers so far (everybody is invited to mail
me info on his models on dbackenkoehler_nospam_t-online.de) -
eventually I will put something in the net, but here are some
preliminary ideas of mine on serial numbers, main boards and keyboards
-> criticism is very much welcomed!

Serial Numbers:
Apple II: initially black on white sticker, later red on white sticker
with model numbers and RAM configuration - A2S00XX is a II
Apple IIplus: initially green on white, later darker green on white
with model numbers and RAM configuration - A2S10XX is a IIplus
Opinion: Apple did not mix A2S2 and A2S1 stickers, despite the opinion
of some ebay sellers, the transition between earlier and later
stickers took place some time in spring 1980 (maybe when the
production in Texas was taken up?), the earlier smaller green on white
IIplus sticker was somehow continued to be used on early US production
europlus models.

Main boards:
Rev. 0 board no part number, initially with light green slots, later
with dark green slots, used from 1977 until mid 1978, ca. until Apple
II serial number A2S1-6000, mail logic boards were numbered
Rev. 1 board 820-0001-01 I have never seen one -> help wanted!!
Rev. 2 board 820-0001-02 I habe never seen one -> help wanted!!
Rev. 3 board 820-0001-03 silkscreened under the CPU, CPU has to be
removed to see it, handwritten numbers on the boards are production
dates, used from 78?? until 7930 (=30th week of 1979), memory select
blocks can be removed, lowest Apple serial number I have seen is
A2S1-14282, highest A2S1-31907, maybe very early IIplus models used
this board as well.
Rev. 4 board 820-0001-04 silkscreened under the CPU, somethimes Rev.
04 is visible silkscreened on the board, used from ca. 7934 to 8030,
16/16/16 memory select blocks are soldered to the board, used on Apple
II and IIplus. Serial numbers I have seen: Standard II: A2S1-33186
until A2S1-39624 (black on white sticker) and A2S1-61091 until
A2S1-65944 (red on white sticker); IIplus: A2S2-04566 until A2S2-32458
(green on white sticker) and A2S2-70974 until A2S2-82343 (darker green
on white sticker)
Rev.7 board 820-0001-07 silkscreened visibly on the board, ca. 8030 to
8111, no memory select blocks, used on late Apple IIs and IIplus,
lowerst serial numbers I have seen are A2S1-66655 (red on white
sticker) and A2S2-89265 (dark green on white)
RFI board 820-0044-01/C/D silkscreened visibly on the board, 8111 to
end of production, no memory select blocks, used maybe on very late
Apple II and obviously IIplus.

Total production - highest serial numbers I have seen so far:
Apple II: A2S1-78944 (there may be a gap in serial numbering from
A2S1-40000 to 60000 - I haven't seen a black on white sticker higher
than 40000 and a red on white sticker lower than 60000) -> help
wanted!!
Apple IIplus: A2S2-544703 main logic board dated 4982
Apple IIeuroplus: IA2S2-600000 to ca. IA2S2-710000, ca. 110.000 units
Apple IIj-plus ??

Keyboards:
very early keyboard, single piece, keycap style POWER-light, the ICs
are visible with the cover open, Encoder MM5740AAE/N, used until ca.
A2S1-02500.
early keyboard, single piece, with the keycap POWER-light, ICs
invisible with the cover open, Encoder MM5740AAE/N, used until mid
1979.
keyboard with the squared raised POWER-light, separate encoder board,
was used from mid 1979 until end of 1980,
keyboard with the even-surface POWER-light, separate encoder board,
was used from 1981 to end, at some point the keycaps got a rough
surface

I can tell for sure that Rev 1 boards are also silkscreened under the
CPU, or at the least that mine is.. !
