memory, upgradeable to 4 MB with a 2 MB SODIMM SGRAM upgrade
module.
Three, 168-pin Gold DIMM memory module sockets support these
memory modules:
– 8 MB, 16 MB, 32 MB, 64 MB, or 128 MB DIMM modules.
– 60 ns Gold SDRAM
Maximum system board memory is 384 MB.
Ports: parallel, serial, mouse, keyboard, USB(two), video, MIDI/Joystick,
audio out/in/mic. mouse, and video.
