I have a very late II+ (sn 58xxxx). For some time I had been under the impression certain games, etc., would not work on it at all due to its age or limitations. However, when I got my Rev 02 Apple II, I discovered this software worked on it. So I figured a II+ ought to be more capable than a Rev 02 and ought to run the same software.
I ran a RAM diagnostic. I remember hitting similar weird issues with my 02 and after reseating RAMs got everything working. Anyway, the diag says no problems on the motherboard and no problems on the language card. However, after starting to swap RAMs on the card I found I could get further into the loading process than before. Never all the way but.. further. Ive swapped all of them with known goods but am still getting stuck.
Are there other places to look? Motherboard RAM? Is there a more efficient way to test these other than 1 by 1?
I notice on the language card there are three leds.. the two closest to the back of the case are solid red.. the one closest to the keyboard does not light. If thst means anything..
