Installing Memory Expansion Cards
There are four slots for 36-bit SIMM memory expansion cards on the
motherboard. You can expand the memory capacity of your PG 740 up to
128 MB using these memory banks. Pairs of cards must always be inserted.
EDO RAMs, fast-page-mode, single-sided and double-sided SIMMs are
supported.
The memory banks are fitted in pairs with the same SIMM type. X19 and
X21 each for the Low double word, X20 and X22 each for the High double
word. 72-pin SIMM cards without parity bit with 1Mx32, 2Mx32, 4Mx32 or
8Mx32 bits in 60 ns fast-page-mode or EDO types are used.
