Beta Disk 128 mini is a controller for 1 to 4 floppy disk drives for ZX Spectrum and compatible computers. During its development, emphasis was placed primarily on the maximum possible reduction of dimensions. It comes from the original interface of the same name from British company named Technology Research Ltd, with which it is fully compatible. "128" in the interface name indicates that it is a version of the ZX Spectrum operating with both 48KB and 128KB RAM.
ATTENTION! Pinout on the IDC34 floppy connector according to the Shugart standard:
Pin 10: Drive select 0 Pin 12: Drive select 1 Pin 14: Drive select 2 Pin 6: Drive select 3 Pin 16: Motor ON
Because the schematic is largely taken from the original interface, is directly compatible with these computers without any further modifications: - ZX Nucleon 512KB - ZX Spectrum 48KB - ZX Spectrum 128KB „toast rack“ with radiator to the right - ZX Spectrum 128KB +2 Amstrad gray box - Didaktik M - Other clone with standard system bus connector and compatible Sinclair Basic ROM are theoretically compatible but not tested

ATTENTION! Because the Beta Disk controller of all versions is historically equipped with an IDC connector wired according to the SHUGART standard (4x DRIVE SELECT, 1x MOTOR ON), it will not work without modifications with new drives with IBM interface (2x DRIVE SELECT, 2x MOTOR ON). In this case, I recommend purchasing my BUS CONVERTOR + SPLITTER for up to 4 mechanics by prior arrangement:
