From a now expired auction, via matrixsynth:
“Vintage Analog drum machine with TR style sequencer, made in Germany in 1987. There’s not too much information available on the VERMONA DRM on the internet, so I will provide some of my own background knowledge. It was released in 1987 by a German synthesizer company named Vermona. These days they are best known for their
analog drum module the Vermona DRM-1 MK3. It is the European answer to ROLAND’s TR-X0X and CR-XXXX drum machines.”
