I have several Apple ][+ machines I am trying to return to functional... this one is missing it's badge on the cover, and the internals look different from all the others.
I am including some photos to show what I mean..
For example, this logic board doesn't have the 74LS02 at A14.
It has these 16K Memory Select chips along side the memory banks.
There is no resistor near the power connector.
There are no disc capicitors in between the slots.
The case screws are recessed and steel, not black.
It came with 16K RAM, and someone added 32K more, plus a 32K Saturn RAM card.
It has 2 x 8T28 chips at H10.
Here's the sticker on the bottom.
Well, what can you tell me about this Apple?
Currently I am trying to repair the power supply, and also get this computer to boot from a Disk ][ drive (and yes, the drive and card are both good. What happens is when I attempt to boot, the drive corrupts/erases the floppy. If I take the drive and controller to a different Apple ][+, all works well.)
