My unit is in a very poor condition. It doesn't work, as
it has few logic chips broken. Because they are shorted, power supply
got a damage too. CRT can't even try to start. Many chips have oxidized
pins, because it was flooded in storage. ROMs are readable.
These terminals were manufactured in Mera-Elzab.
Two Polish computer magazines from 1980s: Bajtek and IKS,
published its photos. In the first one (right) you can see that
extensive testing was performed with many units at once, with
comparable (to Transmit/Receive?) working unit separated on the
other table.
The other photo (lower-right), coming from an interview with Mera engineer
about Meritum, shows us that there were green and amber screened
one-board terminals. These units have probably the same
mainboard as my unit. |
