Let see. What year was this? Do we know what the audio claim is? I would
look but I'm too busy looking at large EPROM data sheets. (ie. 16-bit
samples? Are the samples stereo or mono? That kind of thing.)
The service manual shows two ROMs dropped between two ASICs that look an
awful like 27C400's pin-out wise. I've seen worse. :)
Anyone unsoldered and dumped them? Photos even?
