The Presto Plus processor upgrade card has an onboard RAM expansion
SIMM slot with a 32 MB SIMM that adds additional RAM to your
system. For example, if your computer has 10 MB of RAM the Presto
Plus adds an additional 32 MB for a total of 42 MB. To determine the
amount of RAM available to your system, select “About this Macintosh”
or “About This Computer” (depending on the installed System software)
from under the Apple Menu.

The Presto Plus features 10BaseT Ethernet via a RJ45 Ethernet port. If
you intend to connect your Macintosh to an Ethernet network, you will
require an unshielded twisted-pair (CAT 3-5 UTP) cable. You will also
need to configure the system software (via AppleTalk and TCP/IP control
panels) to recognize proper Ethernet settings.
Two LED indicators on the Presto Plus provide status information for
verification and diagnostic purposes:
• The LED Link indicator
(Figure 9)
indicates a valid connection to
a network. When a connection is established, the LED is on; if a
connection is not detected, the LED should be off.
• The LED Transmit indicator
(Figure 9)
indicates the transmission of
data. When on, the LED should blink on as data is being transmitted.
When no data is being sent, the LED should be off.
