![]() ![]() I wonder when Apple made the switches along the way? Interestingly, I have a system with the "1st state" label in the 11,000s so that means when they switched to the 2nd state (with the amended 1A2S2 designation and blockier digits) they may have the reset the numbering back to the start as well. 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. After 45+ years, it is finally clear who wrote the serial number on the first Apple-1 computers by hand. Finally, I guess since production was ramped up to such high volume, the numbers switched over to a date code (last image). Following that, the label was changed so that the extra "1" was now part of the label, but the serial numbers were still sequential (S/N 76667). This is similar to Heritage Guitars using the letter A. Apple geeks may be aware of the mystery of the handwritten Apple 1 serial number present on some of the surviving machines. The samples used in this paper are digital images which have been preprocessed with data. The number appears to be handwritten, the 2s look more like Zs. In this paper, we recognize serial numbers on banknotes using deep learning. The typeset of the serial number looked just like the early Apple II & II Plus numbers (see S/N 1601 below.this is Mike Maginnis' system). PRS-600.GB.4-153-621-11(1) About the serial number The serial number is for customer registration purposes. ![]() ![]() It seems that soon after its introduction, a "1" was printed in front so it now read 1A2S2, presumably to avoid confusion with II Plus, and the number itself was printed in much larger, blockier text (see S/N 9761). When the first Apple IIe systems shipped in January 1983, the sticker on the bottom displayed an A2S2-XXXX serial number just like the Apple II Plus.
