Delta-S

Delta-S

 The ZX Spectrum computers were made in the end of 80-s. At that time the Soviet Union was still behind the "Iron Curtain" and it was impossible to buy an original ZX Spectrum computer. Those little computers that were imported into the Soviet Union cost so much that it was not possible for an average person to buy one. At that time a lot of illegal enterprises sprung around the country which manually assembled ZX Spectrum clones from the Soviet components. In most cases the computers looked real cheap, but they worked. Only in the beginning of 90-s the Soviet industry at last has started to produce computers, though they were the same ZX Spectrum


clones. Delta-S is one of them. It was made in 1990 in the USSR, in the city of Kursk. This computer enjoyed a big popularity.

Delta-S is a full analogue of the ZX Spectrum. It was based on the Z80A CPU (unlike many Russian clones this one used real Z80A CPUs produced in the West or in S. Korea). Memory is based on Russian K573RF6A (Intel 2764 clone). Computer had a connection for the TV, tape recorder, joysticks and used an external power supply.
