That sounds good. Wait, did you mean the general programming model is keystroke (I know that) or the solver uses keystroke programming (have no idea what that would mean).

I read about that. It may be a good option for extending the keyboard if they haven't abused it. Actually, from the description, it sounds like the way to 50g works for plotting and a few other functions where if you hit a shift key and another key it does one thing, but if you hold and shift it does another.

It broke after a few weeks? Or you sealed it up for Y3K, or...?

Anyway, yeah this is what I'm looking for history, background, technical info on etc. Thanks.
