Today we will build Zepto #Forth and flash it to the Pi Pico and do an introduction in this awesome esoteric language, that I hadn't used for 30 years either. But I rediscovered it looking into web-assembly, with is also a stack based language.

![CODING LIKE ITS 1989
We will be coding a Turbo On/Off switching tool for an old Compaq, based on Adrians Digital Basement episodes.
We will learn how to:
-load registers
-if then else statements (when arg is 0 then turbo off else, turbo on)
-read form memory
-write text to screen
-write to IO ports
The code we will create:

The dosbox TASM development environment, to code along:

THIS NEEDS TO GO IN YOUR DOSBOX CONFIG FILE
[autoexec]
# Lines in this section will be run at startup.
# You can put your MOUNT lines here.
