Wersi DX-5 Organ / Synth? Anyone have any info?

There is one for sale by me, but I can't really find any info online about this. Sure looks cool though. Anyways, and info woulf be great, and if anyone here has one or has played one before let me know what you think!

Thanks in advance

Here is a picture of the organ:

Lord man, go listen to it!

The instrument was an entry level model that was introduced in the mid to late 80s, and had some cracking sounds for the time, more details can be found below. (It was based on the Wersi Omega organ which had the same sound system as the MK 1 Synth.
Hope this helps
