2-2 PEM-3300 Motherboard
If your motherboard is the PEM-3300, the layout of your board be as
pictured on the next page.
The PEM-3300 motherboard uses a cache memory subsystem provid-
ing a small amount of fast memory (SRAM) and a large amount of slow
memory (DRAM). This system is configured to so that all system
memory is fast memory — fast enough to complete bus cycles with no
wait states. The cache memory provides high performance with no wait
states. The cache memory provides high performance with a cost
approaching that of DRAM.
The motherboard contains a Intel
coprocessor socket, BIOS chips and expansion slots. The figure on the
next page will familiarize you with the layout of the PEM-3300 Cache-
386 33MHz Mainboard.
