Circuit and design considerations for interfacing the PDP-8
computer and a Printec-100 line printer. Three patches
convert the TTY instructions in "FOCAL" and "EDU-10 BASIC"
and "FORTRAN" to output to the line printer. An assembly
language program to printout all the alphabetic and numeric
characters for testing purposes is included as well as an
overlay for FOCAL which uses a "P" command to cause either
the teletype or the line printer to be used for output, accord-
ing to the setting of a switch on the switch register.
