I am mainly involved in the development, modification and repair of hardware for the Spectrum, mainly on discrete elements, such as Pentagon-128, Profi, Scorpion, KAY, as well as branded machines.
I also took part in the development of software for computers such as Karabas-128, Karabas-nano and of course Karabas-pro and mostly talked on the zx-pk.ru forum, but now I rarely go to it.
I lived until 2022 in Ukraine, in the Kharkov city, now I live in Krakow. After moving, I am now mainly engaged in modifying the hardware for the ZX-Evolution computer, both the motherboard itself and the equipment for it - ZI-FI, VDAC2, NEOGS, Multisound and ZXNETUSB.
