- '-' 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
- 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.
