Kay 1024[1][2][3] was a Russian clone of the ZX Spectrum[4] that was produced in 1998.[5] It was made by the NEMO[6] company and had 1024 KB of RAM.[7] It was a rival to Scorpion ZS 256, having a slightly lower price. It had a controller for a PC keyboard and HDD but not for floppy disks, although it was available as an extension card. Adding a General Sound card was easy, and the CPU had a 10 Mhz turbo mode.
