ADLIB/MPU-401 Expansion bay

Post by t9999clint »

I like the chirpy sound of the PCjr and Tandy, but there were a bunch of early PC games that just sounded best with a MT-32 or Adlib card.
I've seen these adapters for the Tandy systems but I can't find anything like this for the PCjr.

There's a bunch of opensource projects like HardMPU that can add MIDI support and simular projects for OPL cards so it's definitely possible to make them with mostly modern parts and AFAIK they don't require DMA access so it should be compatible with the PCjr's "ISA" bus.

Yeah! Is there any info on the modem card? Maybe it could go there also?

I have a PDF file that outlines a Serial/MIDI/XT Keyboard/2nd and 3rd floppy multifunction card for the PCjr. I don't know much about this card but here is a link to that PDF. http://www.linearlogix.com/PCJR/PCjr_Combocard.pdf
