Expansion Chassis power input.
3.2.4 Connect a powerjumper cable from the Expansion Chassis power output to the
Macintosh power input.

the Macintosh and Expansion Chassis power switches to the ON position.
NOTE: The MacCharlie power switch can now be used as the master switch for turning
power
to
the system
OFF
and ON--as long as the Macintosh and Expansion
Chassis power switches remain in the
ON
position.
3.2.6 Connect the communications interface cable from the Expansion Chassis
communications outputport to the MacCharlie communications input port.
:
3.2.7 Tighten down the communication interface cable connector screws to prevent the
cable from working loose.
3.2.8
Tum

switch.
NOTE: At this point, the MacCharlie application should appear on the screen.
If
instead, the screen remains empty, re-initialize the MacCharlie application from
the Macintosh Commands menu.
4.0 Insta1Jin2 Cards
·The Expansion Chassis can be used to add up to six full
or
half-length
IBM
PC compatible
cards to a system. This is accomplished by simply inserting a card into any one
of
the six
card slots provided. Each slot is equipped with an individual power and signal interface
connector that links the MacCharlie with the Macintosh. The card slots are located along the
left and right sides
of
the Expansion Chassis and can beeasily accessed by removing either
Expansion Chassis side panel.
Before installing cards in the Expansion Chassis,
it
is important to understand certain
characteristics concerning the MacCharlie. Since MacCharlie uses a parallel port (LPTl) and
serial port
(COMl)
and assumes that a monochrome monitor (Macintosh monitor) is
connected,
it
may be necessary to reset a card configuration to accomodate this arrangement.
Also, like the IBM, MacCharlie when used with anExpansion Chassis is limited to three
direct memory access (DMA) channels. These channels are used by devices such as floppy
disk drives, hard disks (or cards), network interface cards, and possibly interface tape
backup cards. Since the Expansion Chassis provides so many slots, it is conceivable to
attempt to add more than three
DMA
devices. This is notpossible, however, due to IBM's
system limitation, unless the particular device has some defeat mechanism.
Instructions for setting up and installing most IBM
PC
compatible cards are the same, with
the exception
of
those for installing Enhanced Graphic Adapter (EGA) cards. Because EGA
cards use a second monitor they require additional setup procedures.
If
installing this type
of
card, skip past the Standard Card Installation instructions and go directly to the following
EGA Card Installation instructions.
NOTE: TheExpansion Chassis does not support co-processor cards (super-chargers
and turbo-chargers)
or
cards having greater than 640K memory.
If
using a
card with greater than 640K memory, disable the memory before inserting the
card into the Expansion Chassis.
