notes
- can be installed in three ways:
- into a Zorro II slot
- to the 26 pin expansion port of a Buddha, Buddha Flash, Catweasel Z2, ISDN Surfer, X-Surf or another VarIO (Hypercom, ISDN-Blaster and Highway are incompatible)
- to a clock port - only possible with a special version of the VarIO that is only manufactured on order (the difference is the voltage level converter)
- clock port pin 40 is marked
- if installed into a Zorro II slot the clock port or the 26 pin expansion port (only one of them at a time) can be used for expanding the VarIO
- clock port allows using expansions initially designed for the clock port of the A1200
- when installed in Zorro slot, pin 40 of the card's clock port is towards the front side of the computer, pin 19 resp. pin 1 towards the rear side
- marked wire of clock port expansions go to pin 19 or pin 40, depending on the manufacturer's definition - e.g. expansions made by Individual Computers are installed with the red stripe on pin 40 (to the left), expansions of E3B mark pin 19 / pin 1 (to the right)
