My first computer came with a Hazeltine 1000, this was older than the 1200. It had 80 characters wide, but I think it only was 12 lines tall, I cant remember that part for sure. What I remeber for sure was that it was upper case only. There was a place of the PCB for a second character generator rom for lower case which was not loaded. There was also a switch on the front which enabled lower case for the keyboard. That was very confusing because sometimes I was typing in lower case, then when I did a search or search / replace in ed it couldn't find what I was searching for because it was upper case. I didn't figure that out until later when I got an intertube terminal to replace the Hazeltine 1000. Les
