I decided to play around with the video ROM in my IIe lately.  The big problem
I came up against was that the Apple IIe Technical Reference Manual says the
video ROM is a 2333.  I couldn't find an EPROM equivalent 2733 anywhere, so I
decided to try a 2732.

The thing works!  Now I want to know if (1) Apple made a typo in several places
in the manual or (2) if I'm missing something.  Text and graphics work as well
as they always have.  Of course, I could be missing something else, that (3)
the 2333 is a variant of the 2332, which is the ROM equivalent of the 2732
EPROM.

Any answers from Apple's hardware gurus (or anyone else) on this thing?  Thanx
in advance!
