2.3 Adding cards
The 4-slot passive backplane accepts half-size CPU and I/O cards.
Slot number S4 has a little bit more space than the other slots. This
slot lets you insert a CPU card with an on-board piggyback/PC-104
module. We strongly recommend these all-in-one cards, for they
are durable and save valuable slot space by bundling a CPU with
hard disk and floppy disk controllers, as well as serial and parallel
ports.
At the side of the chassis, four bracket holes under the mounting
bar match the four backplane slots. You will also find two smaller
holes that you can use to install external D-type connectors.
When adding a card, slowly slide it in, carefully press it into the
backplane socket and secure it with a screw to the top mounting
bar. See Fig. 2-2. Refer to card manuals for wiring. Install
additional cards. When you have finished, reattach the top cover
and rear panel.
