Its not true that it has better compatibility with Pentagon than in Spectrum, because of russian ULA. There was almost 100$ compatibility with Spectrum. Two design difference were slightly problematic, but do not cause leaning to russian clones which were even addressed differently etc:
a) ULA - provide refresh for all adressing space - it means, all memory space have issue with wait states. Therefore, to bring better compatibility, CPU was running at slightly faster frequency, so approximatelly memory access timing was almost the same. This bring two results: exact timing demos wont work correctly, when uses attribute change to bring 8 colours per attribute, and writing to border was out of timing as well
b) different copyright messages in ROM, different charmap (bold fonts) and corrected original bugs caused incompatibility only when tested by stupid games protection, this was not real issue.
The most problematic part was the keybord. It was meant to be build as high-quality replacement for original membranne, however, it was a real disaster. It lasts about 2 or 3 years of everyday usage, then it starts to have contact problems, and, plastic parts came to colision with each other and with metal spring.

Price in 1991 was about, if translated to euro, 100EUR. Was a very good clone of ZX Spectrum, almost 100% compatible, I did not see any game or application from ZX that could not work on DIDAKTIK M. I used it for long time. Keyboard was not so bad, needed a bit of training to get accustomed for it, but printed commands and letters on the keys faded away very soon with often using. But I have only good reminds about it...

My first computer... oh the emotions are coming. We used a tape player to run the games at the beginning. It took about 10 minutes to load one game! Imagine how wonderful it was to get a floppy drive that would run a game in three seconds. Playing Dizzy, the best game I've ever seen...
