Large numbers of old CP/M machines were 40, 64 or other column widths (even less than 40 in some cases). HHGTTG does not assume an 80 column screen if my memory is correct. It’s configurable and it picks it up from CP/M when possible (CP/M 3 provides the video width). Certainly I’ve played it fine on a 40 column screen
Yep checked. The byte after the initial JMP in the binary is the width setting and was adjusted according to the machine it was sold for.
