> The Atari ST had a MIDI port: that notoriously lacked on the Commodore Amiga
I never really understood why people thought this was a big deal. I had my Amiga hooked to a DX7 synth with a serial to MIDI cable that had a couple active parts in it. MIDI is a serial protocol and the Amigas had full RS232 ports with hardware interrupts, +12v, -12v, as well as audio in and out on unused pins. The serial to MIDI In/Out cable cost around $15 more than two MIDI cables. You can still buy them today: https://retroready.one/products/ka12-serial-port-midi-interf....
