Unofficial production in ZVT Banská Bystrica
One Slovak collector has a PMD-85-1 "clone" in his collection and shared the information:
"The initiative at ZVT Banská Bystrica was quite interesting. Maybe up to 40 pieces were produced there as a side project, which they called a "display unit". " or amateurs on universal boards. My opinion is that they covered it up in production so that they could make boards. Anyway, I have two "ZVT" keyboards from PP01 :) . And I know of two other surviving pieces. More modern components were used there, for example, 2764 or even 27128 type."
