I have one. I will power it up sometime this week.
I'm not sure how its configured. It's been a while since I powered it up.
I have one as well, but only tested it a bit using RT-11.
So I can't help you at all.
YES!!, the hard drive is MSCP compatible and can be
accessed via the DU(X).SYS device driver. What is
UNIQUE (at least I have NEVER seen any other system
using the same hardware) is that the 8" floppy drive accepts
both RX02 (SSDD) and RX03 (DSDD) media using the
MSCP device driver, DU(X).SYS, rather than the expected
DY(X).SYS device driver.
In the case of the RX03 media, however, the head switch
occurs after every track - if I remember correctly.
The result is that RX02 media are completely compatible
with the DEC RX02 device driver, DY(X).SYS, and can
be swapped back and forth - although not hardware
booted, of course, since the boot code is for the actual
hardware.
BUT, for the RX03 media, the (never tested) code from
V04.00 of RT-11 first uses one complete side, then the
other. In general, this means that the RT-11 directory
is OK, but the files can be read only using the device driver
that they were written under.
