* '-' means 'signal ignored in this mode'
* MDA/CGA/EGA and Commodore 128 - signals are in the same order as on computer output, so standard DB9 1:1 cable is enough to connect this machines to Medusa
* digital RGB mode - used mainly with Sinclair QL - you will need DIN8 to DB9 cable (pin numbers for DIN8 are given in the table)
* Apple IIC - to connect Apple IIC you need cable from DB15 to DB9 (pin numbers on DB15 are given in the table) - when you prepare cable for Apple IIC be aware that there is 12V on pin number 8 - DO NOT CONNECT THIS PIN !!! - it may destroy Medusa.
