A “shaggy dog” story is a category of story in which a large number of words are used, but with a wholly disappointing and uninteresting conclusion. Why do I mention that? No particular reason. So, the Service Manual for the Sega ST-V Saturn-based arcade board mentions the existence of a “MIDI OUT” port. But what does that mean?
The Sega ST-V service manual doesn’t say much more than this. A three-pin connector, JST NH 3P, labeled “MIDI OUT”. It doesn’t go into detail, beyond mentioning that for additional connectors, you should look at their manuals. But I haven’t been able to find any service manuals mentioning it.
Rodrigo Copetti notes that the SCSP, the Saturn Custom Sound Processor, has MIDI support, and even on the Saturn it’s output on its rear “communication connector”. This connector was pretty rarely used, but there was an adapter to 5-pin MIDI sold in Japan.
The SCSP actually has two MIDI outputs, for MIDI IN and MIDI OUT.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
