Had my TRS-80 on for a long time and could not save the high scores so took a screenshot with a camera It's on my Google photos here: photos.app.goo.gl/s58LRt5fVUmX8HC6A It was very good took that photo can see the comma goes under the button of the letters so I did have lower case. When I solder in a RAM chip to make it 8 bits wide the lower case did not work. It's because I had a Level 4 in Livonia MI. Fix the RAM and it took them over a month from that I remember. They must of took out the lower case chip and sold it. I had to order another one I think it cost like $40 or 50 from Radio shack way back then. Grate video showing this.
