I bought a new Amiha 2000 this week, and looking through the schematics
in the back of the (German) user's manual, I noticed the familiar
(from my A1000) memory overlay line (OVL). It went from a CIA (as
is to be expected) to GARY.
This makes me wonder. The 2000 doesn't need a boot rom, does it? The
start of the kickstart ROM has the same structure as the boot rom
in the 1000. (I know; I disassembled it). Does the OVL line maybe
map a PART of the kickstart rom to location zero? Or is there a
boot rom anyway?
