3.24. DRAM-SIMM SOCKETS
A 4-Mbyte SIMM is mounted in the DRAM-SIMM socket as standard. This socket can hold a 72-pin
SIMM (known as a module in the case of DOS/V machines) with a capacity of 4 or 8 Mbytes, and can
also accept an EDO type DRAM-SIMM in addition to normal DRAM-SIMMs. Select a DRAM that
satisfies the access timing requirements by referring to Section 7.3. The capacity of the connected
SIMM can be read through the PIO port. (See Section 6.6.)
3.25. ROM SOCKETS
The RTE-V852-PC has ROM sockets to hold 40-pin ROM chips to provide standard 128 Kbytes (64K
×
16 bits). When the standard ROM is replaced to enable the use of a Multi debugger, connect ROM
having an access time of no more than 150 ns. When mounting RAM of a different capacity, it may
sometimes be necessary to switch JP1 on the Base board. (See Section 3.16.)
