Description:
Trying to use hardware tabs at the console of a 780 doesn't
work properly. Apparently the LSI-11 software expands
tabs and characters with the parity bit set confuse its
calculations.
Repeat-By:
Log on at the console of a 780 and type 'stty tabs'. Do an
'ls /' and note the uneven columns.
Fix:
Don't set the parity of characters going to the console.
