Greetings. I am new to this group and came here because I have a plan. I would like to use the coco i picked up for robotics. after studying the tech manual I descovered that there are pins at the top and bottom of the cartridge port that seem to be unused, and that there is a block of ram marked unused. My goal is to create something that will use the otherwise unused part of the coco to control 8 relays and read 8 switches without making the computer unable to use any of its capabilities. For example. extending the cartridge port so that packs still fit in, but the pins i need are used. So that the robot can walk into a room, you can plug in a cartridge and it will still work. Something like interfacer-80 by alpha for the mod iii would be ideal. low budget and something i can build myself are considerations. thanks in advance for any info John B.
