Someone asked for *any* information on running a TE16 and RM05 on the
same controller. As I remember, these run off a massbus controller.
Back in my 11/70 days, RSX could not support different devices on one
controller. The problem was not hardware; the controller could
serve 8 devices in any mix. The software could not handle the fact
that the controller had only one interrupt vector. I think that
later versions of RSX were supposed to fix that.
There is also the performance issue. The massbus only handles a block
data transfer from one device at a time. However, it also has a
separate control bus, so that (for example) you can issue a seek on a
disk while a tape is doing a data transfer.
P.S. As I am new to the new, would someone please send me mail or post
a response so I can tell if I am getting out into the world.
