VarIO Zorro II (Amiga)

For all Amigas with Zorro-Slot and Amiga 1200 

VarIO is an interface-board with a serial and a parallel interface. The performance data of the serial port is identical with the Silversurfer: 16 byte fifo memory, 460800 Baud maximum transfer rate, low CPU load and high compatibility with existing software.
The parallel interface has been speeded up dramatically compared to its predecessor Hypercom: It has also got 16 bytes of fifo memory that lower the CPU load by far. The ECP mode (extended capabilities port) improves communication speed with modern printers.

The special thing about the board is it’s great possibilities to be connected to the computer: At first sight, it looks like a Zorro board that is equipped with our standard expansion ports: an standar clockport for connection of a Silversurfer, and a 26-pin expansion port. In case the VarIO is not plugged into a Zorro slot, it becomes an expansion module for one of our Zorro-boards, or an A1200 clockport-module (special version) that is connected with a cable. This results in eight different ways of using the VarIO:

Zorro-board as base model: 1 x ser, 1 x par
Zorro-board with Silversurfer: 2 x ser, 1 x par
VarIO on X-Surf Ethernet: 1 x ser, 1 x par
VarIO on ISDN-Surfer: 1 x ser, 1 x par
VarIO on Buddha (Flash): 1 x ser, 1 x par
VarIO on Catweasel Z-II: 1 x ser, 1 x par
VarIO on VarIO: 2 x ser, 2 x par
