*NOTE: Components listed above from all 3 board revisions were verified from analog boards that I myself own. Boards were examined thoroughly to ensure complete accuracy.

Board "630-0102-none" is the very first Mac 128k analog board (indicated by the lack of a revision letter at the end of the number), manufactured in 1983 -- it has a gray paper cover over the solder side of the board,

and hardly any hot-glued components. Board# 630-0102-E is "Revision-E" of the original analog board, stamped "86 10" (October 1986: most likely the date of manufacture) -- has newer vinyl cover over solder side

of the board, and most components are hot-glued to the circuit board. Board 661-0462 is the last revision Apple every created of this type, Mac Plus Platinum version (my Apple Service Part box for this board is

dated 1992). I have seen up to "Revision J" of the 630-0102 board advertised on EBAY.

FINAL NOTE: There are 3 axial electrolytic capacitors on Mac 128k and 512k logic boards that would be worth replacing with tantalum capacitors:

33µF 16V, 2 pieces

4.7µF 35V, 1 piece
