Does anyone have any information on the analog sound board option for the Soundchaser? Speedyg has extensively documented the 2 mountain computer music system cards for the digital option, but there seems to be very little online about the analog option. So far I've been able to find 3 pictures, 1 is B&W and from 1982, and the other 2 are lifted from an old ebay listing that the rest of the photos are gone from. Neither is close enough to make out ICs, and the boards in the pic from 1982 is a different design and presumably revision from the 2 in the eBay listing. I've come across a couple of soundchaser keyboards, which I went into with the intent of just making clones of the digital boards, but thought it'd be neat to dabble in both territories.
