Today, I built a MIDI card for APPLE II.
It is one of my wish item and successfully develop as the Passport compatible.
So, now I can play the Ultima V with Passport MIDI output.
I don't have real passport card so, I had to research with the passport driving program and refer the manual.
It tested on APPLE IIe and also need to test it for APPLE ][+ and IIGS.
It have MIDI IN and MIDI Out as general use.
I will announce again when It ready for sale.
I recorded one of good song.
I used a PC with USB MIDI cable and connected to this MIDI card.
