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

Yes, I was able to run the echo characters test from the solivant site
as well as a couple other small upload tests, so I'm thinking it's a
delay issue or a configuration problem with the 3P+S and MITS BASIC.
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
