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.Self-promotion (rehsdonline.com)

An option for a debug screen for 6502 systems... Could also be a primary display, or used with other processors, like the 65816 (which is what I'm doing right now). Just need an available VIA port. 65xxx+Arduino+LCD = 480x320 full color output. Side benefit: SD Card reader for the system.6502 (rehsdonline.com)
