Pics of the inside below. Note the art on the circuit board. Looks like two dudes poking cells. If anyone knows what it is and/or where it comes from feel free to comment.


"You are looking at a vintage 1979 Sequential Circuits Model 700 Programmer, used to add 64 patch memories to an analog synthesizer. No small feat in the days before synthesizers had built-in patch memory! Sequential only produced a couple hundred of these programmers and as a result, they are extremely rare and very hard to find, especially in this condition! According to the circuit board, this is a mk 2, rev 1 variation of the original, adding a single cable connection to the synth you wish to control. To the best of my knowledge, this programmer is fully functional. I purchased it years ago from a gentleman who demonstrated it for me and everything was working at the time. Unfortunately, I no longer have any synthesizer gear to test it with. I can say that it does power up and that all 8 tactile switches respond properly, with their respective LEDs lighting. The 2 digit screen at the center of the programmer lights brightly, just as it should, and changing positions on the memory bank rotary switch and pressing the tactile buttons change digits on this screen just as they should. All knobs and switches have a firm feel to them, no sticking or sponginess of any kind. Cosmetically, I feel the photos speak for themselves. This one is in EXCELLENT cosmetic condition, with the front and top panel showing no signs of flaking or corrosion whatsoever. Wooden sides are in excellent condition as well. Rear panel and bottom show some VERY minor paint flaking, but no actual damage, and nothing that will cause this flaking to become worse or spead. Circuit boards are in excellent condition with no damage at all. I will remove and replace the old 3v battery inside prior to shipping, as it is more than ready to come out. Depending on when this programmer sells, it may take me a few extra days to replace this battery. If the purchaser would prefer not to wait for a battery replacement, I will happily ship with the old battery removed."
