Hey there,
I have come upon a couple IIGS cards labelled "Doctor Design". They are
simple cards with a single IC (M8842) and a bunch of resistors/caps.
They have 1/4" headphone jacks as outputs and a speaker on/off switch
which are mounted on a backplate. Some plugs go into various motherboard
sockets, and speaker cord apparently passes through the board.
I thought this was a stereo output card or something-- but there are only
two leads connected to the headphone jack. Anyone know what these are
for?
Thanks
Ben
