Little is known about this Slovak clone of the ZX Spectrum.

One of its particularity is that it has a separated reset button and two joystick ports (1 Kempston + 1 Sinclair). But both joystick ports have non-standard connectors.

The ULA (video chip) is different from the one used in the original Spectrum. It's a russian circuitry, and it results in the screen being square instead of rectangle. Because of these russian ICs, the Diaktik M was actually much more compatible with Russian Spectrum clones (like the Pentagons) than with original ZX Spectrum.

The Didaktik M seems to be sold as a 64 KB RAM computer but only 48 KB is available.

Two models of the Didaktik M were produced (90 & 91). The Didaktik Kompakt is in fact the same computer with a built-in floppy drive on the right side of the unit.

A 3 channel sound interface with ACB stereo called "Melodik" was also available, as well as a 3.5" external floppy drive called D80.

Didaktik M and Kompakt are still sold online here!

Richard reports to us:
There was external 5.25" floppy drive produced called Didaktik D40. I think it was able to take memory snapshots with a snapshot key located on the connector to the floppy. Later there was Didaktik M Kompakt produced which had 3.5" floppy integrated on the right side of the unit. I used this computer to play games, was fun.

Predseda (Czech Rep.) adds:
It has one of the most uncomfortable keyboards ever. Keys are unnacuratelly attached to the computer´s body and it makes their pressing really painful. Quick typing on its keyboard is really impossible, you must press each key separatelly and with special care.

and Petr adds:
It has 4MHz CPU, different from original Spectrum and must be braked - some instructions has another size of tact. RAM is 64 KB but only 48 KB is used. There is no difference between slow and fast memory. This computer is much more compatible with Russian Spectrum clones than with original ZX Spectrum.
