the channels, A and B, the data transfer is tested
in the loopback mode for each channel. The
loopback test connector must be connected
before the start of the test. (See 2-2, for the
connection method.)

When no ROMs are mounted in the PROM
sockets, 2, 3, and 4, the checksum
for the banks
4 through 15 will result in OO. For the test
ROM
1. is mounted in the PROM socket 1, the
checksum
test is carried out for each bank, in
total of four banks (8KB x 4).
