[Coco] MPI 26-3024

[Rogelio Perea]

The 3024 MPI is the bigger unit, upgradeable via the updated PAL chip.

The 3124 MPI is the smaller newer unit, the one with the satellite
board upgrade.

The URL provided points to a page with *more* than a photo, and I quote:

"Here's a simple test that will determine if your Mulit-Pak has
already been upgraded to work with a CoCo 3. From BASIC's OK prompt,
type PRINT PEEK(&HFF90) and press ENTER. If 126 is returned then the
Multi-Pak has been upgraded. If it returns 255 then it has NOT been
upgraded."
