The PMD 85 could be connected to the Variel network.
In addition to official production, there were also home-made PMD-85 clones. One collector shared his catch:
"In terms of design, it's like an hp85 from behind the iron curtain. :)
Monitor is silelis, magic is sm1. The PMD itself is on its own professional board with a keyboard with hall pickups.
The Rom module is now replaced by a single eprom+8255 on a separate board. The interaction of the board is from pmd origo with modifications.
The most interesting thing is the central part of the PMD, it is beautifully done at a professional level, and especially the keyboard takes it to another level compared to the classic PMD. Something like Didactic Alpha or Armourer."
