The //e is a ][+ with most of the logic in a pair of

memory control and I/O). It has 64K RAM on the motherboard (the ][+ has
48K, with an optional 16K language card), and can take another 64K RAM,
bankswitched. IIRC, the //e also has an 80 column display using a very
simple expansion card, and an extra multi-colour video mode.
I don't know what you mean by the "extra multi-colour video mode", but the
later //e's (the revision B and Enhanced versions, not the original
revision A) had the capability for double hi-res. This meant that it
could do 560 x 192 graphics in 16 colours as opposed to the standard 280 x
192 in 8 colours.
I have a //e somewhere. I never did much with it as I
didn't have a Tech
manual (the ][+ came with such a manual). Then, amazingly, I found the
official Apple //e technical manual in a bookshop in London. Of course I
bought it. Maybe I'll dig the //e out again and play with it.
Guaranteed to brings days, weeks and years of fun and challenge.
