It was equipped with two 5¼″ drives typically K5600 made in East
Germany (users complained about the quality of these drives) with a capacity of about 100 KB. But other manufacturers' drives could also be used, eg Bulgarian IZOT 5255E. Supported disk capacities are 100 KB (single density)

The reception of the computer was initially positive, it was seen as the first Polish personal computer. Later opinions tend to be critical. The press pointed out technical specification is not impressive, especially lack of graphic mode. Besides, TRS-80 was an unknown computer in Poland. There was

From 1984 to 1986 Mera–Elzab produced 2,500 units. The maximum production capacity of the plant was 4000 units per year. The computer was assembled in one room, where 5 people worked. Production of one computer consumed 20 man–hours. The computer accounted for 1% of the production value and at the

The company expected that due to the price the computer would not be available for individual users. Small businesses were the primary target market, followed by research and education institutions. They expected the computer would be also used as an industrial controller.

In 1985, Mera–Elzab submitted to the
Ministry of Education a proposal to create a network version of a computer for Polish schools. In this configuration, the Meritum II computer with a connected disk drive would act as a

The computer never became popular, mostly because of a low number of units produced, the price and technical specification were not competitive to other products, and lack of software and documentation.

At the end of the first year of production, the computer was slightly modified by adding support for Polish characters on the screen, a keyboard with Polish characters and the memory was expanded.
