The
TRXPN
is an expansion board for the Total Recall project. It allows one to use four MN3008 BBDs in place of two
MN3005 (both totaling about 550ms of delay). The TRXPN has its own bias trimmers for the two added BBD stages and
when wired to the TR main board, they are inserted as stages 2 and 3 of the delay. This makes the exact sequence of
BBD stages as follows (referring to both the TR and TRXPN schematics):
