In the old PC mags, there were often printouts of code from Commodore PETs. How were these done? Even though the PET had a GPIB interface, it didn't have a print command.
The method that we used in 1978 was a little machine code program to show one line at a time on the top of the screen and then screen scrape it and send each character to the GPIB. This worked but was quite slow.
Was there a better technique for achieving printouts?
