Tandy TRS-80 Micro Color Computer Model MC-10

MC-10 Open Box


Don't actually know a ton about this computer. It was given to me a couple years ago in it's beautiful box but I've been unable to test it as I don't have a TV with the proper inputs to use with it. Someday soon I hope! It looks like at some point someone did a hardware mod of some sort. Here are some pictures including the mod.
