I have been testing the waters of Atari APX Pascal recent and have been having an issue with MEDIT blowing up when run from the Pascal menu. I twittered the great Bill Lange who gave me the fix.
(1) As you probably know, you have to copy the MEDIT executable over to your work disk image in disk drive D2. In addition, MEDIT needs a minor modificatio...

Learning Action! I, finally, am getting around to learning Action! My goal is to learn Action! to create a sequel to my Atari 2600 game 'Parsec 2600' on the Atari 8-bit.
Anyway, the best way I have found to learn something is to teach others while I'm learning it. So, here it goes.
Action! is a cross between 'C', Pascal with a little bit of Assembler thrown in for good me...

few days ago I commented on re-evaluating the Color Computer and
how I now appreciate the simplicity of it's design.
Well, I wrote my 1st program for it: Awari.
I originally wrote Awari for the TI-99 (see post in TI-99 IUG).

a couple years back I got a Color Computer 3 for $20. the guy said that it was busted but I thought, why not. Turned out I was able to get it to work and resold it for $150.00. I even managed to get 'Drive Wire' to get to work on it.
ever since then I have been toying with the thought of getting another Coco. I even did get a Coco 2, very briefly, but it...
