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
Did you verify "echo characters" works?
There is a test program in the
solivant site that explains this. If so, then you very well may need to
experiment with character delays when you download BASIC. You can watch
the lights and see when the various loaders load, that might help give you
a clue where the failure point is.
The extra pointers I added were things I found useful,
but I was using the
2SIO card.

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