I used http://www.vintage-basic.net/downloads/Vintage_BASIC_Users_Guide.html as a reference while writing the interpreter so it should be pretty close to MS BASICs of the early '80s. The Guide leaves a few unanswered questions ("should logic short circuit?" for example), but proved sufficient to get my interpreter working enough to run StarTrek (for some yet to be determined definition of "run").

The local university had a HP2000, and installed a terminal in the high school, and there I spent many a lunch hour and time after school through my high school years.
They had printed out the entire program catalog and posted it on the wall, so my friends and I who wanted to know how this stuff worked our way through the list alphabetically. You could load a program into local memory and edit a copy. We would change things around and see what happened. In this way we taught ourselves BASIC and programming.
We ignored that oft repeated advice to go thru the whole list first before beginning. Imagine our dismay when, after a few years, we finally reached the letter T and happened upon the series of programs titled TUTOR1, TUTOR2, etc. that taught you how to program. By that time, we could have written those tutorial programs!
But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Romans 5:8 (NASB)

How about BASIC on an ISC 19" color terminal? $work used these terminals with an add-on IR touch bezel for control system operator interfaces.
I wrote a real estate investment model on the ISC(way before VisiCalc existed). It was a very nice moon-light job as the customer kept adding features!
