Dubis7 Posted April 18, 2021 Share Posted April 18, 2021 Badge aside, how can I tell an Apple II from a II Plus motherboard? Last year I picked up what I believed was an original model II. I say that because it came with the earlier raised powerlight keyboard. The lid had long since disappeared before I got it. If it is an original II, it's definitely a later revision from the absence of the memory select blocks. The ROM chips are all copyright 1978. I'd turn it on to check but it needs repair - won't boot beyond the power light coming on. Any help is appreciated! Quote Link to comment Share on other sites More sharing options...
Keatah Posted April 18, 2021 Share Posted April 18, 2021 Pretty certain that most Apple II+ units will have at least a Revision-1 motherboard. Quote Link to comment Share on other sites More sharing options...
