RX02 / DSD440 problem

Tom,

if there is no apparent software solution (what kind of ROM is in use,
is the bootstrap entered manually in octal, ...?), a quick fix might be
to swap the drives or their cables inside the box so that the working
unit becomes number zero.

But, Jerome is right, once we know what kind of bootstrap you use, it
should be possible to replace the unit number. - If it's not such a
tricky beast as the four-word-bootstrap for RL02 disks that uses some
power-up defaults to initialize the controller registers. In such a
case, the sequence would become longer, but it should still be possible.

So, what does your dialog normally look like when you boot your /23?

Regards,
Andreas
