[Simh] Re : Disk number restriction

[Hittner, David T (IS)]

Just to follow up: The SIMH VAX comes up in the default configuration
for a MicroVax 3900.
.. Only one 4-port MSCP disk controller (RQ) is enabled by default.

You have to add the other controllers and/or disks to the simulated
hardware configuration with:
 sim> set rqb enable
 sim> set rqb0 enable
 sim> set rqb1 enable

Rich's advice is good. RTFM :-)

Patrick,

The oldest version of SimH I have easy access to is 2.10, and even there
the
VAX simulator supports 4 RQDX3 devices (RQ, RQB, RQC, RQD) and an RLV12
(RL =
RL01/RL02), each of which can support up to 4 disks.  At some point, the
780
simulator added the RP (RP04/05/06/07 and RM02/03/05/80 Massbus disks)
and HK
(RK611 with RK06/07 drives)) devices with 8 each of their respective
drives.

Take a look at the documentation for the VAX simulator, under section 2
(VAX
Features), to see what disks, and how many, are allowed.  Or just type
the
command "show config" at the simulator prompt, to see what devices are
available and whether they are enabled.

Good luck!

                                                                Rich
