Is it located at the Adlib I/O ports of 388/389?
Nice work! It's good to see someone creating their own peripheral boards. :thumbsup:
Yes, it is ISA compatible but the IBM PS/1 models 2011 and some 2121 don't have ISA connectors. Instead there is a 34 pin header to attach a very rare PS/1 Audio Card, so I used it.Wow!Excellent work!Can you tell us more info?It it ISA compatible?(I see no ISA connector)
Nice work! Would love to see this documented into a wiki of some sort, with detailed schematics and pictures, especially since this seems to be adapted to use a proprietary connector found in the PS/1 (which I've sadly never gotten to crack open and experience)

Thank you for the information. I found a clock signal in the 34 pin header but it is not the 14.318 ISA clock, it seems to be the system clock (10 MHz) because the OPL3 plays tunes in a lower pitch when feeded with this clock signal.
This is an old thread but if you would either post schematics and parts so I could build one that would be awesome. Or if you would be willing to build one to sell me I would be very interested. I love the 2011.
