Default Retro computer homebrew: Orton ASR33 terminal

Well, this project has had my customary three month 'snagging' period for quality assurance

I have tested the cassette save and load system on my SC/MP NIBL computer emulation (documentation for which will follow shortly). It was able to save and load the biggest possible NIBL program - about 570 lines of empty 'REM' statements - without error.

Fun fun fun!

That is so cute - I want to make one... I love the real TV tube. Was the keyboard an off the shelf one or did you make it from scratch?

Karen, this is really quite beautiful! Have you any pictures of it running I'm interested in how your font looks and the video generation for the PIC.
