The Kay 1024[1][2][3] was a Russian ZX Spectrum clone introduced in 1998.
It offered a controller for a PC keyboard and HDD, but not for floppy disks (although available as an extension card).
Adding a General Sound card was easy, and the CPU had a 7 Mhz turbo mode.
[8][9] The Kay 2006 NB (North Bridge) is a 2006 version based on the Altera EPM7064 MAX.
It adds three new graphics modes: Multicolor, GigaScreen and 512×192 pixels in 2 colors.
