Hungarian variant of the M-125-3 Fialka
As a country of the Warsaw Pact, Hungaria also
used a variant of the M-125-3
that was adapted for the local language (Hungarian).
As no surviving Hungarian Fialka machines
have been found so far,
we do not know the keyboard layout of these machines.
During one of our trips through Europe however,
we discovered a complete Hungarian Fialka wheel set,
which is presented here.

Hungarian wheel wiring

In July 2014, during one of our trips through Europe, we discovered
a complete set of adjustable Hungarian Fialka wheels which a 5K prefix.
This set has clearly been used, but is in extremely good condition.
More importantly, the set is complete and all wheels have matching serial
numbers. The wiring of the wheels is given below, but can also be
downloaded in XML format.
In this table, each row represents a wheel, whilst each column
represents a single contact on a wheel. At the top of the table are
the entry contacts which are at the right side of the wheel
(i.e. the side with the spring-loaded contacts). The table itself
shows the output contacts (i.e. the left side of the wheel).
The positions of the Advance Blocking Pins are marked in red.
At the far right is the total number of Advance Blocking Pins for
each wheel.

When testing a Hungarian Fialka, either as a real machine or as a simulation,
the following table might be useful when checking the wheel stepping mechanism.
Put all wheels in their default setting (i.e. ring set to 'A', matching
core with side '1' up with the mark set to 'A') and place them in the machine
in the default order: АБВГДЕЖЗИК. Now lower the ruler and set the wheels
to AAAAAAAAAA (just above the ruler).
Next, type 30 random characters on the keyboard and compare the position
of the wheels after each step with the following table [2]:
