I had an external monitor which certainly did 80x24 - I think there was a program you ran

IIRC, that resolution required an add-on board that piggybacked onto
some chips on the main board. The higher reolution also works with the
built-in monitor, although that makes it a little hard to read.
Without the additional board, I don't think the Osborne-1 supports 80
columns.
