[Coco] PAL Chip?

[Little John]

CW,
As I mentioned in my email directly to you, the 74LS785 is the SAM chip. And 
I have also verified that the other chip is the 6847T1 VDG. These are from a 
later model (such as the 26-3127B) CoCo 2 motherboard. I would be interested 
in buying them if you decide to sell them. I can also provide a CoCo 3 
upgraded or Tandy Original PAL chip for the 26-3024 MPI or an upgrade kit 
(requires soldering) for the 26-3124 MPI for your friend (these were 
developed by my son but are proven items).
