Pretty sad that it took me over a year to look inside my second MSB2. But I've recently expanded my rig, like a good GS member, and I needed the extra capacity.

The newer one actually has a revision number on the main board (Rev. 16). It's a lot cleaner layout. I think the newer barrel-type power connector is part of the revision as the rear panel has the polarity in the silkscreen. The resistors near the optoisolators are gone, replaces with resistor arrays. The optos themselves are now socketed.

I still think the pushbuttons on the front panel were replaced, and probably at least one of the LEDs. The soldering there looks a little different.

This one was probably just made a few years later than the first.
