Meritum TRS-80 /2 clone

The Meritum was a TRS-80 Model 2 clone. It was manufactured in Poland by the Mera Elzab factory, which produced electronic measuring devices. The machine was not very popular. It was slow, lacked graphics, and had no floppy disk support. RAM could be expanded to 64KByte, but there was not much compatible software that could run on this machine.

The system was briefly considered for educational purposes in Poland, but due to the lack of graphics it was quickly rejected and the Elwro 800 Junior computer was chosen instead
