Yeah, the docs were on fold-out sheets at the back of the manual! I
think I even had schematics for the floppy disk controllers. the
Apple ][ was a really nice machine - I remember I had, (infact, still
have, although I haven't powered it on for around 10 years!), the
following peripherals in mine:

Slot 0 - Language card
Slot 1 - 16K RAM card
Slot 2 - Empty
Slot 3 - Z80 processor
Slot 4 - Third disk controller
Slot 5 - Second disk controller
Slot 6 - First disk controller
Slot 7 - PAL encoder

I only had four floppy drives, so the third disk controller was never
used. I didn't have an 80-column card, nor a serial interface :-(,
but I did have *** 96K *** of RAM!!! Truely the power of a mainframe
on the desktop... Almost.
