[Coco] CoCo2 Strange Side Switches

[John Goerzen]

Hi,

So I got a lot of random untested CoCo parts off eBay yesterday.  It
included a CoCo 2 which seems to have been modified or something.  On its
left side are two unlabeled switches:

Anybody seen this before?  Any idea what it's about?

I haven't plugged it in or anything yet, because I want to understand what
these switches are about first (if possible).

Obviously, my original CoCo 2 doesn't have these.

Thanks,

John
