The RL11 sure is, but I thought the rx02 was "by hand", i.e. not a bus master. It probably doesn't matter, since if it isn't it probably loops NPR on the card. -brad Nope, RX02 uses NPR, thus CA1-CB1 must be cut. RX01 did not use NPR, it was programmed I/O. Nt sure if RX01 has the CA1-CB1 jumpered on-board ... there are a few (old) UNIBUS modules that do *not* have a jumper on those two contacts! If RT-11 runs, you can do .SH CONF and see the addresses/vectors. Perhaps there is something. - Henk.
