Simmons SDS-1 Drum Machine Synth Pad & EPROM Chips

"Vintage Simmons SDS-1 EPROM-based electronic drum pad in perfect operating condition, including 30 different Simmons SDS EPROMs... The Simmons SDS-1 is a single voice drum synth that uses 8k or 16k EPROMs. The drum synth can be triggered by hitting the drum pad or via an external trigger input.
