VIC-SWITCH
USER'S MANUAL
GENERAL INFORMATION
VIC-SWITCH enables eight VIC 20 or CBM 64-computers to communi
cate with the same pripheral devices. If more than one user wants to
communicate at the same time, the VIC-SWITCH will put them in a
queue. The waiting users will get access to the peripheral devices in a
consecutive order, i.e. number 2 is served before #7. But if #6 is com
municating at the time #2 and #7 asks for a peripheral device, VIC-
SWITCH will open the channel for the user connected to number 7 as
soon as #6 has finished. In this way no priority is given to certain users.
VIC-SWITCH should only be connected to COMMODORE products
designed for serial IEEE communication e.g. FLOPPY DISC VIC-1540,
GRAPHIC PRINTER VIC-1515.
CONNECTING AND PREPARING VIC-SWITCH
On the front panel, shown in Figure 1, there are nine LED's. The left
most LED is lit when the power is on. The other eight indicate which
computer communicates with a peripheral.
The back panel, Figure 2, of the VIC-SWITCH consists of nine DIN
sockets and a connector for the power cable.
The leftmost DIN socket should be connected to the peripheral devices.
The other eight are input sockets for VIC 2Q/CBM 64-computers.
However, all eight inputs does not have to be used-any configuration of
up to eight will work.
