Although I've written several CP/M CBIOSes, I've never had to write one on
a system that used the Trap vector (0066h) for something essential.
Just curious--has anyone had to deal with servicing the Trap interrupt in
CP/M? How does one keep CP/M from clobbering the vector, since it's in the
FCB2 area?
Cheers,
