IMM Alfa 10 - The first Polish terminal
Anyone knows if any unit survived? I don't have such terminals, but there's no information about them in the net, so here is what I have.
IMM Alfa 10 was the first character-based terminal built
in Poland. Earlier for computer input/output teletypes were used. The
terminal was built in 1972/1973 in "Zakład Wejścia/Wyjścia Instytutu
Maszyn Matematycznych" - Input/Output devices department of Institute of
Mathematical Machines in Warsaw. It was used with different machines,
- Odra 1300 series (it's quite well known)
- JS EMC (Unified System machines)
- MERATRONIC - an accounting automation system consisting of another implementation of MOMIK 8b microcomputer as MERATRON central processing unit (?evolved to Mera 300-series?), Facit automatic typewriter, CTK-50/DKT-50 perforated tape reader/writer and PDm-1 disk memory. [Source: Informatyka, 1973/03]. Probably never left prototype stage.
As it can be read in Informatyka 12/1972, the production
itself was realized by ERA plant. The parameters, given there and in
"Młody Technik" 6/1973, are as follows:
- 18" CRT tube, 306 lines, 50Hz
- 960 (?40x24?) or 1040 (?40x26?) characters
- Latin and/or cyrillic font
- 5x7pix character
- Blinking cursor (~3Hz blink)
- Keyboard with cursor and function keys
- Interface compatible with electronic typewriter interface.
- Built with integrated circuits.

Probably "Production grade" unit.
