Adding composite video to a Tandy/Radio Shack MC-10.

I recently bought a Tandy MC-10 off of Ebay. “Why?”, you may ask. 


A friend of mine had one back in the day or I might not have even known about it. I always thought it was an interesting little machine. 

Though it’s very under-powered, even for it’s time in it’s default configuration, like many other retro machines, it’s expandable now in ways that Tandy never intended it to be.  It’s also fairly easy to get on Ebay, so it’s cheap, and maybe most importantly, it’s really small, so it’s easy to make room for it. 

Here you can see it’s size compared to a few other machines…


As you can see..pretty small.

One of the machine’s main shortcomings is the fact that by default, it only has RF video out. Fortunately that’s easy to fix these days. You can replace the machine’s RF out with a small composite board from the Zippster Zone.

I bought one of Zippster’s composite boards and installed it in an afternoon a couple of weeks ago.

I chronicled the entire process in this Google Photo set.


The other place that this machine comes up short is that by default, it only has 4K of RAM. Also, the version of BASIC on it is very stripped down. Both problems are rectified by the MCX-128, also from the Zippster zone
I have one of those on order…
