Elwro 523 has 12kB ROM, 48kB RAM, two 8" disk drives, and works with CP/M 2.2 compatibile system.
Beside desk case, there's Robotron printer and Neptun 156 monitor. The total weight is around 200kg and power consumption is 600W. The computer is switched on with a lock and key (like in cars).
Whole electronics is placed in the middle cabinet, under the printer. At rear side there are doubleleaf doors and after opening them you can bend the arm with electronics boards. Disk drives have own build-in power supplies and are connected to ~220V socket-outlet inside.
I own the whole electronics, two 8" drives, Robotron printer, most of paper documentation and ~70 8" floppy disks with software. Unfortunately I had to loose most of the case. At this moment I don't have time to scan documentation and make photos of the boards.
