Software
I don't have much software for the Pecom and what is available is not in English (except the ported COMX basic game Trainspotting). What is however funny to see is that the Pecom has one game, Osvajaci Svemira, which is very similar to the COMX Space Invaders game, see screen shots below! Main difference are the colours and the shape of the bullets. It really looks like both games were based on the same code.
Available software in '.Pecom' format which is loadable in the emulator:
