Does anyone has a revision list for the Apple II? A list with descriptions of the revisions would be great. How many revisions were there? How do I tell what rev my Apple II is?
I read a posting about 8-bit fonts, and was confused as to what these revisions were. The bit about rev 7 and lower-case letters I have not heard of before - it doesn't sound correct to me:
Apple’s first professionally built computer was the Apple ][ which from rev 7 onwards added lower-case letters.
The upper-case, numbers and symbols were copied from the Signetics 64 × 8 × 5 character generator 2513 chip used in the Apple I and II in revision 0 to 6.
Changing the font requires replacing the 2 KB 2716 pin-out ROM with your own EPROM or alternate ROM.
