I built a 16-bit ISA sound card for my 286 system! It has six sound generators (YM2149) and its own co-processor (65816). I have a series of videos where I go through the PCB design and the build out of the PCB. I have the schematic posted, also. 6

  1. /r/vintagecomputing would appreciate this.

  2. Good God, how long did this take you?

  3. This is awesome but the fact that some of those chips aren’t lined up is bugging me. I’m obsessive about lining everything up neatly and make generous use of “snap to grid” features.

  4. That’s actually kind of impressive.

  5. How does writing commands to the dual port sram work ?
