[Coco] Coco interfacing, running a coco from 12 volts and more.

[haywire666 at aol.com]

I'm new to this mailing list. I used cocos for ages back in the day, ages past everyone else moving on too.


Lately, I've been working on a mobile robot project of sorts. I was going to use a micro controller for controlling it but I 
remembered how great the analog inputs (joystick ports) were for sensors and things like that and I decided to try and use a coco.


I got some old cocos I saved out of some bins in my basement, but so far things have progressed very slowly.


I need info on using pia chips to get digital i/o lines in and out of the coco. After goggling for ages, I found very little on the subject of
interfacing with a coco, which is a shame, I'm sure I remember tons of projects like that in rainbow and other coco magazines.


I also need info on running a coco3 from 12 volts. Right now I'm using a voltage inverter and its terribly inefficient. I'm sure running direct from the 
12 volt gell cell would add tons of run time.  Right now the battery gets drained pretty quick!


If anyone has any old magazine articles that they could scan, or can give me ANY info on these things I would sincerely appreciate it.


If I don't find the info I need I will have to use a microcontroller I guess, but I would REALLY love using a coco for this.


Best regards,
