Many years ago (March 2007 to be precise), I posted to this mailing list because I had
typed in (by hand) the octal listing of TBX (Tiny BASIC Extended) from Dr Dobbs Vol. 1 No.
1, pp 16-17(
It turns out that this 8080 code basically worked and I was able to verify it in a Z-80
simulator.
Fast forward to 2025, and I have rediscovered this code and posted it to GitHub. I have
also included an 8080 emulator in JavaScript so you can run TBX in your browser:

While keying in two pages of octal listings was an interesting exercise, I’m less keen to
type in the source code for TBX, which appeared in Vol 1 No 2, pp 13-31.
I’d like to preserve this source code alongside the octal dump in my github repository.
Does anyone happen to have a listing of this source code in ASCII, or perhaps access to
high quality OCR software that could perhaps automate the job?
The closest I can find is on Whipple’s own web site
athttps://whippleway.com/Source_Code/TBX.asm
Which seems quite close, but is missing things from the first TBX (e.g., FOR / NXT
loops)
Many thanks,
