I found another similar board here with a high enough quality image to be useful.

I'm noticing they don't have the second voltage regulator like package on Q4. Right and down an inch or two from the voltage regulator that supplies the 3V for those cpu types.
Does anyone know what the purpose of this package is? I'll have to have a look and find it's datasheet when I get home if not.
Thank you
I'm also noticing now some browning on the solder joints of my regulator for 3V. I'm wondering if that's a sign something went bad or if it was messed with at any point and that's leftover burnt up flux.
Edit: I'm gonna retest the regulator... Probably just gonna check the vcc and vss through the socket instead of trying to hold my probes on the regulator itself. I'm still a bit confused as to what the second package is though, a second regulator? The same thing?
Edit2: I'm thinking I'll replace the regulator with a TIP31C, but I'll confirm what the swap will be once I get to it. I'm noticing other boards of this type (other versions at least) seem to all use a TIP31C so I'll just go with that.
