Could you please dump this as a .bac file:
1 INTEGER
2 WIDTH 40.
3 WIDTH 80
ABC-bladet seems to indicate that ABC806 uses a weird internal encoding
(a double escape) for "WIDTH" and "ATTRIBUTE", but it also says "ABC806
only". I know ABC802 has WIDTH, so I'm wondering what its encoding is.
Trying to improve the BASIC-II support for abc80sim. At some point I'll
probably add the necessary I/O changes to simulate an ABC802 entirely.
I would love to find a circuit diagram and ROM dump from an ABC800C some
time, but since ABC802 was the main ABC800 I used "back in my day" it is
the most interesting to me - and of course it is pretty trivial to add
color or even HR-graphics to the 802 design.
