[Coco] Converting MC-10 Basic to Coco Basic

[Charlie Pelosi]

Hi Robert.

The MC-10 allows entering the text graphics right from the keyboard when holding the control key. The same way it allows entry of basic commands with a single key stroke. If you look at the keyboard you can see the commands and text graphics silk screened on the computer. If I remember right, you cycle through the color used with the text graphics using control 0. Maybe, it has been a long time.

Here is a good page that shows the keyboard.

I saw that an MC-10 program was recently uploaded to the
http://www.colorcomputerarchive.com/ with an interesting name, SwelFoop; 
actually Swell Foop aka Fell Swoop. I just had to look at that game. :)

Well the upload was in .c10 format which when changed to .cas did load into 
MESS. However as the tokens for MC-10 Basic don't match those for Coco Basic the 
results were not useful. I did find an MC-10 emulator into which the game loaded 
correctly. I then printed it to a PC file which was loaded into MESS as an asci 
Basic file.
The game with LIST was almost correct with a few strange results.

It seems that MC-10 Basic permits placing low res graphic characters directly 
into PRINT"" statements without using CHR$(). When the program was LISTed in the 
MC-10 emulator the PRINT statements displayed the graphic characters. When 
LISTed on a Coco, you got PRINT at T+32,"";. The content did not display even 
though the data could be seen when the program was examined on disk.

I can't even guess how such data was entered into those PRINT statements.

Anyway, I've uploaded a Coco version of the game to the archive.
