Apple II

I looked around and haven't found a really good reference list for iie books that a newb might need. But, I've been doing my best finding and filing books that might work. I've  ordered the most important ones... so far as i can tell:

Manuals to have on hand

On a related note to the question about squares, I'm a little confused by the "color" word :). Specifically as applied to the iie. I like the visible computer program that shows how the 6502 works from the inside out (the apple/commodore program, not the modern thing). But, it "works" in color, which means it comes up like this:

I wanted a ROM card to round out the  toolset and picked this up on ebay. Arrived today and I realized it was more than a clone of the apple integer rom card. More chips. Looking at it, I <think> you can install diodes on the pads on the lower left to selectively enable specific ROM chips. 

Anyone got documentaion on this? I looked on Apple2.org and they had a front photo but nothing else. 

Also, any idea why they differentiate between PROM and ROM in the silkscreen (above the pads - lower left)

Cheers

I just got an Apple II off ebay. It has a broken 4 and Reset key. I thought I could fix the 4 key with a swap of the repeat key but whoever attempted to fix this keyboard broke a lot. Many of the little plastic pieces that hold the metal switches (not ALP like swithes) are gone. So alignment is tough. I may take some thin nails and use them as guides. The though hole for the 4 key shaft is messed up. I couldn't get the repeat key shaft into the 4 hole and I can't see where the exact problem lies yet.
