You can find a few demos of a Percuter in previous posts here.
"The Dynacord Percuter is a simple drum module that lets you trigger 8 sounds with pads or sequencer.
Very basic features, only a pan and sensitivity control for each channel, as well as independant outputs, and a master stereo output and headphones outputs. There is a cool global pitch control though.
And of course the real nice feature is the ability to change cartridges and thus change sounds as you like. They were many cartridges made and their sound quality is extremely good, in the league of the Linn Drum, Oberheim DMX and such, if not better.
Unit was cleaned and checked and It's fully working and response well to trigger pulses.
8 cartridges are included and they build a full drum kit (a ride or crash could be nice though)
- 111001 Electrified Bass 2
- 111020 Natural Snare 8"
- 111002 Electrified Snare 2
- 111004 Electrified Tom 1
- 111005 Electrified Tom 2
- 111006 Electrified Tom 3
- 111047 Accent Hi Hats Cymbal
- 111048 Closing Hi Hats Cymbal
Please note that P20 and Percuter sound roms are the same (nature snare for instance) they are totally different sounds. The Percuter sounds are 8 bits and the P20 are 16 bits I think. Samples are brighter and longer."

"This nostalgic drum machine is for sale due to studio downsizing. Probably one of the first .
One example is said to be in the German museum.
It is fully functional and still looks quite fresh.
A piece of plastic is missing from 2 gray toggle switches at the front.
All the capacitors have been replaced so that it runs without any background noise.
Very organic, powerful sound, produced by coils and germanium transistors, among other things.
230V
Width: 60 cm, depth: 28 cm Height: 9 cm"

Buchla Tiptop 264t | Buchla 200 Series | Episode 14 | Quad Sample and Hold / Polyphonic Adaptor
video upload by Cinematic Laboratory
"The original Buchla 264 is a very rare module, released in the 1970's. So it's important to realize it's a very primitive way of adding polyphony to a modular system. It's not that different from an early analog polysynth, where voice cards were used to activate two or more voices from a keyboard 'switch'. This is another fine example of doing easy things the hardest way possible, so there should be some reward in it. Apart from the polyphonic switching mechanism - you'd need four VCO's, four envelopes and four VCA's to switch between. I'll start with four Plaits, which can trigger their own internal LPG while distributing Marbles CV/GATE between them.
Then I used the Buchla LEM 218 keyboard to try and make chords. It didn't work so well, because the 264T is too slow picking the right voltage for the right key-down event. The 218 already outputs quantized notes in the 12-TET scale, so how hard could it possibly be to 'sample' the voltage from the played key and hold it? On the original Buchla 264, people used a gate lag (with the 281 envelope generator), to sample the voltage first, and trigger the hold with an end of cycle, just a few milliseconds later. Fortutnately, the 264 also has track and hold. In this mode, it can simply track the keys from the 218 keyboard, and hold it on key down. Works like a charm!
Regardless, this old-school analog polyphony is a lot of work and requires either a lot of modules, or specialized quad versions of your basic VCO, VCA and Envelope Generator. However, the module provides lots of cool resources you can use on a simpler setup, and results may be even cooler than trying to create polyphony. For instance, the polyphonic adaptor can double as a clock divider, which is missing from the current Buchla/TTA 200 series. It's super useful to clock a delay or sparse event. When combined with the 242 pulser, you could use a 11-step sequence, and pick every 2nd, 3rd or 4th event, creating all kinds of odd variations without changing the 'pins'.
Then there's ART, which is a new digital protocol for tuning a VCO, and sending quantized note and gate information. This requires an ART capable VCO like the 259T. While it's tempting to use two of those, it's much more fun to just use the principal VCO in ART mode, and use the modulation VCO in standard mode. Your voice will be in tune with other sources, but you'd still be able to create some new textures and leads. Quantized notes will steal some of the Buchla magic, so this is a best of both worlds. So if you're not pursuing polyphony (which isn't unwise), the 264 is a great source for stepped random voltages, divisions and quantized notes. Highly recommended for all you generative music lovers."
