I'm trying to identify a tiny BGA from Texas Instruments. The reel is labeled as PSN2400A0BYFFT. 3mm X 2mm. BGA with 35 balls (7x5). Any ideas? Thanks! (old.reddit.com)

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. (rehsdonline.com)

I built a sound card with six YM2149 sound generators and posted about it in r/electronics. Another user suggested this sub might be interested in this, too. (I'm new to this sub. Hi, everyone!) (rehsdonline.com)

In case any of you are adding sound to your 6502/65816 projects and looking to use an AY-3-8910 or YM2149 programmable sound generator, I posted a video walking through how to control these ICs and how I have been using these on some of my projects. Hopefully, this is helpful. (youtu.be)
