Installing 28-Pin Devices in 32-Pin Sockets

Figure 4-3 displays 28-pin devices in 32-pin sockets. Pins 1, 2, 31, and 32
are unused, (socket pin 3 becomes pin 1 of the 28-pin device, socket pin 30
becomes device pin 28 etc.).

Static RAM Jumpering

To install Static RAMs (SRAMS), jumper the byte-wide sockets according
to the contents of Table 4-7, and then plug in the devices. Connect the off
board battery to provide back-up power to the SRAMs. See the Battery
Backup Configuration section in this chapter for details of battery connec-
tions.
