The AR-B7041 provides 8 sockets for memory chips. Each AR-B7041 card also could be piggy-backed 1 AR-
B7017 to have more sockets for more memory capacity. Five combinations of AR-B7041 and AR-B7017 are valid,
they are as following:

The AR-B7017 accepts the same kinds of memory chips that the AR-B7041 uses. Every AR-B7017 provides eight
32-pin JEDEC DIP sockets for a maximum of 4MB FLASHs, EPROMs or SRAMs. The AR-B7017 is installed on
the AR-B7041 through the piggyback connector CN1. When you create the ROM pattern files with extensions
exceeding .R08, the files with extensions .R01 to R08 are placed in the first AR-B7041 card from MEM1 to MEM8,
and the files with extensions .R09 to .R16 go into the AR-B7017 installed on the first AR-B7041 or the second card
from MEM1 to MEM8 if no AR-B7017 module, etc.
If no AR-B7017 is used, the locations and sequence of memory chips are listed on the following table:
