M 312

The M 312 is a black-and-white monitor with a plastic (reduced size) cabinet, made by Electronica in Bucharest [1].

A note to the table of portable sets says that Electronica „now” made three types of black-and-white monitors: M 113 (sheet-metal cabinet), M 213 (plastic cabinet, normal size) and M 312 (plastic cabinet, reduced size) [1]. In the same table, the column for the monitor gives a TK 31 cm (110°) picture tube (and, in brackets, a TK 31 cm, 90° one), a plastic cabinet of normal size (and, in brackets, of reduced size), no channel selector and a 220 V, 50 Hz or 12 V DC supply [1].
