Interesting item popped up for auction. As usual, I have no affiliation with the seller or the auction. Just pulling the shots and info for posterity. Title link takes you to more shots.
"Produced in the early 80's - from the same era as the Roland Boss DR-55. Controversy still rages as to who copied who - Boss or Sound Master?
It's totally analogue and is in SUPERB condition, with it's original box, owners manual and sample-pattern book.
There are 6 x 16-step (4/4) patterns and 2 x 12-step (3/4 or 6/8) patterns, with A and B variations of each. You can play just A, just B, A followed by B or A then B every 4,8 or 16 bars (like a fill-in).
There are 4 totally analogue and groovy voices - Kick, Snare, Closed Hat and Cymbal (actually more like Open-Hat).
There is a foot-switch input for stop-start and, for you sequencer-heads, a Clock Out +5v trigger on every pulse or every Cymbal beat.
It runs on four Walkman batteries or an AC adaptor (not included)."
