Onboard System Memory Size
The PEMT2630 mainboard can accommodate up to 8MB DRAM on-
board of module RAM (41256,44256 end 411000 types).
If necessary, the PEI-306 RAM Board can increase system memory to
a total of 16MB.
The PEM-2630 has a 30-pin single-in-line socket for SIP module RAM.
Remember that when module RAM is inserted into the sockets, you
must make sure that pin 1 of a module is lined up with pin 1 of its
socket. Remove any static charge from your body before touching the
module. Gently push the module RAM into the socket, and be careful
not to bend the pins.

A jumper is a kind of switch which uses a plastic cap with a metal
interior to connect (short) two pins. If a jumper needs to be left open,
you should save the cap for Mure use by covering one pin only of a
jumper. This has no effect on the function of the board while it keeps
the cap handy. The illustration below shows the side and top views of
a three-pin jumper in which pins two and three are shorted.
