From my records Apple changed from Rev 4 MLB (820-0001-04) to Rev 7MLB (820-0001-07) sometime between 25th week of 1980 and 30th week 1980 (the supplement of the owner's manual also states "mid 80"), so there were Apple IIs and Apple IIpluses with Rev 4 MLB (which had memory select jumper blocks soldered to the board). An Apple price list dated March 1981(!!!!) still lists the standard Apple II for sale aside the IIplus! He has obviously been around for sale longer than I had expected.
Exactly--the Apple ][ was sold simultaneously with the ][+ well into 1981. -michael NadaNet networking for Apple II computers! Home page: http://members.aol.com/MJMahon/ "The wastebasket is our most important design tool--and it's seriously underused."
