As I've mentioned in past posts... I'm thrilled with the sound produced my
old 50CT fed into an old top end automotive Sony cassette/receiver and
Carver 60WRMS amp in my truck. When I put on head phones and play soft
music, I can hear the low signal to noise ratio of the sound chip start
brewing a storm.

It's a OPL-3 Yamaha as far as I can remember, but where info??

I could swear I just got this link to Xin's page from this list a few months
back. It covers adding a mono mic and stereo line-in. Though the latter
wasn't clear enough for me to figure out. Xin says the capability is there
in the OPL-3, but that Toshiba, "was too lazy to set it up." Being able to
record into a digital sound format on the Libby would bee great.
