Hi, I just entered the world of PCjr ownership about a week ago. Attached is my jr with King's Quest, but I am having some issues with sound. Other than that it's working fantastically given the age. The entire idea of being able to stick a cartridge in it blows my mind.

That's a pretty nice system you have there ... the PC Enterprises expansion chassis are not very common.

What problems are you having with the sound?

Thanks! The sound is exactly as drignor described here. I haven't gone too in depth yet with tying to trace it out on the board as suggested in that thread but if I use the RCA audio out and hook it up to a amplifier, I do hear sound but with a lot of noise.

I hope no one minds me doing some thread necromancy but I wanted to share a sound update. I haven't completely solved my problem with audio but I was able to get audio from the LM358's Output B pin. I jumped that to the Audio Out RCA and it works enough for me.
