I have changed my mind. My next project is going to be a multiplatform spreadsheet in BASIC. This would not be the first time I have programmed a spreadsheet, but the last time I programmed it in C for Windows and Linux. This time it will see how well I can make a SS for older computers like Atari 800, TI-99/4A, and old DOS computers.
First to see what I am dealing with, I did a math accuracy test:
100 PRINT ATN(5)
RUN
TI-99/4A TI BASIC displays 1.373400767
Atari 400/800/800XL/130XE displays 1.37340076
IBM PC GW-BASIC/PC-BASIC displays 1.373401
My guess is Microsoft purposely chose this accuracy level to promote paid products.
The cable I purchased has worked really well. still factory sealed, from 1979! Just opened it, looks, feels, and smells like brand new! I dumped a hundred TI-99/4A WAV files on my virtual tape drive and it is great!
So another successful experiment with my TI-99/4A
