Most of these BASICs required a delay on a return. To make it more fun, it got longer the larger the program.

Digging back into this on my IMSAI, I'm now remembering the peculiarities of loading MITS BASIC when I was doing it on the Altair. That picture will help. I think I've already spotted something without even having my actual card in front of me. Thanks...Win >Did you verify "echo characters" works?
