I have second piece on Ebay now.
Rare collectors piece from 90' from east Europe.
Made in 1990 by Brno Small Arms Factory in Czechoslovakia.
Caps are thick doubleshot ABS.
Uses TESLA Hall sensors - it is a copy of the Micro Switch SW or SD Series sensors made in central Europe in 1980's and 90's.
Equiped with Tesla MHB8048 microcontroler (also can be equiped with MHB 8748C or Intel 8748).
This keyboard is able to equip with Soarer's converter or similar to work on modern PC via USB.
Condition:
Used, cleaned - may has some dust or mess. But the caps will need more precise cleaning, I was afraid to pick up them from the board. It needs more power.
Tested, everything works.
Caps are in perfect shape, with rough surface. Yellowed. No chips or scratches on the top, only several small scratches and chips on the sides caused by incorectly storage (only in thick plastic bag) and some imperfections made in factory.
Damages:
I did not see any severe damages, but I could miss something, except one crack in the back corner - repaired from the inside - welded.
Plastic body - perfect, with some small scratches in the corners, caused again because of storage. Yellowed.
Without original box.
Contains a copy of original manual and reference.
Tested on PC XT motherboard. Keybard works nicely - sturdy feeling during typing - rough, this old model comes from early 90' when typing ergonomy was a bad word here
