This board still has the memory select jumpers (16/16/16), but they are
soldered to the board now so that with this revision 4096 Rams could
not be used any more. The numbers on the board still indicate week of
production (8004) and the computer shipped in Feb 1980.  When was this
board introduced? Does anybody have computers with Sn. between 14000
and 39000 to check what board these have? I suppose it might have been
introduced with the introduction of the IIplus in mid 1979 that could
not accept 4096 Rams any more. Does anybody have a very low Sn Apple
IIplus to check what kind of motherboard this shipped with?>>

My ][+ (7000 ser # range) has a Rev 04 mboard with prod date of 8025.

What main boards did these late production Apple II computers have? Is
there anybody out there who has one of those, and who could have a
look? >>

Are you sure about that?   I was not aware that Apple sold that many
]['s (not ][+).
