Delta-C

The following information came with the Delta-C with the Quantum-BK-like grey/white keyboard:


The "Delta-C" is a Russian clone of the ZX Spectrum+ manufactured in 1991 at a former military plant, near the city of Zelenograd. Fully compatible with the Spectrum+, the Delta came equipped with 48 kB of RAM, video output, cassette in/out, two joysticks ports (both Kempston and Sinclair), RGB adjustment controls, and its own expansion port for Russian hardware.
           
The Delta originally sold for about 620DM, and sold very well: for a few months it was on the bestseller list in the region. It has been reported that the machine may have actually been re-baged unsold Spectrums from the UK. Such reports include reports that various stickers cover up hints of made in the UK and official Sinclair badging.
