Performa 6116 - Apple Dos Compatibility Card - Roland MT-32

#1 Wed, 14 Aug 2013 - 07:58

I am thinking of getting an apple dos compatibility card for my performa 6116 for dos games. I would like to ask if there is possibility to connect a roland mt32 device for the music.

The answer is a big "maybe". Apple's own pinout doesn't show the game port outputting MIDI signals, but that doesn't mean its true. If you have the card, I would do testing with a multimeter and see if +5V is present on pin 15 of the game port. If so, I wouldn't connect any MIDI device to the machine as that is supposed to be the MIDI-IN pin!

I can confirm that the card does NOT support MIDI I/O on the Game Port. +5V is present on pin 15 so do not attempt to connect any MIDI devices.

Interesting... can programs running on the DOS card/s access a Mac serial MIDI converter?

So i guess for dos games with roland mt it is better a real pc or dosbox.

Not possible. The defacto standard for external MIDI port communication on a DOS machine is a UART located at 300h or 330h that is register compatible with the Roland MPU-401 MIDI interface. Its silly that the joystick port doesn't support MIDI. The Creative Labs VIBRA chip set used for sound on the DOS card has all the necessary functionality built into it.

Well, yeah. What I'm asking is whether PC Setup is smart enough to capture that and re-route it to the Mac side.
