[Coco] MPI help needed

[tonym]

switch=2,rom=2, exec&HE010 gives garbage.
switch=1,rom=2, exec&he010 gives like a clear-the-screen, and OK prompt at top line.

but... powered off, switch=1,rom=1, power on = cartridge autostarts.

You should try EXEC&HE010 with the rompak in (a) the switch set for the
slot the rompak is in, and (b) the switch set for a different slot.  If the
rompak executes only when the slot number matches the switch, then the
switch is working and it is only the autostart pin that isn't functioning.
