Phil, (01)
Your plan seems fine, but I have two minor comments: (02)
1. In your "Type D" pinout (for the Alto keysets), shouldn't you also
list the ground pin? (From 05b_KBD.pdf, sheet 5, that appears to be pin 19). (03)
2. Although your proposed scheme using a "Type D"-to-gameport cable
seems fine, an even more direct approach would be to take an ohmmeter or
other continuity tester and "ring out" the Alto keyset: attach one lead
to ground, another to the pin for key0, then press the various keyset
keys and verify that the zeroth one (leftmost or rightmost?) closes the
circuit; repeat for the other four pins purported to be connected to a key. (04)
