26-3024 was the larger style, that started out grey, then later white. This model could be updated for the CoCo 3 by swapping out a PAL (?) chip.

26-3124 was the smaller style, always in white. This one had a different update that was a small circuit board or something...wasn’t it?

Where there different board revisions for MPIs?
