[Coco] question about MPI and Orch-90

[Bruce W. Calkins]

There was a mod that piggybacked the PAL chips with a switch to shift from 
CoCo 1/2 mode to CoCo 3 mode.

Update. I have opened the MPI and discovered a few things.  First, whoever 
modded this saved an alternate PAL chip stuck inside upside down as can be 
seen in this pic:   http://cl.ly/image/253N3V1v112c

This second pic is the currently socketed PAL chip:

Hopefully u guys can read the number.  So the question is, which PAL chip is 
currently in there?  Is it the one for CoCo3? Perhaps the spare one stuck 
upside down in there is the one for the CoCo3?
