Hello, everyone!
A while ago I noticed some memory space not mapped in the PAL memory space.
There is 768 bytes between $1400 and $1700 and It occurred me to map an ACIA adapter there, or something else. For an ACIA I would go with a very compact board using a CPLD like a 22V10 type. I could use the rest to map a small ROM, again using a 22V10, to house a wozmon to work in tandem with the ACIA.
Does any one know of any hindrance to map that chunk of address space? I could breadboard everything and discover by myself, which I would eventually do, but there is a lot of other things that I would like to breadboard instead.
Thanks for any information.
Best Regards,
Ronny
