<> REALLY?!?! What are the hardware requirements for V7? I thought they
<>were a lot more restrictive than that. I'm assuming that it does not
<>support MSCP disks.

No MSCP, RL02. ;) I'd need to run 2.11 to get MSCP.

<No, it doesn't, but it does run on any Q-bus machine with an MMU and
<suitable disks. I've had it running on an 11/23 for the best part of ten

I forget if V7 needed I&D space or 2.11 meaning the 11/23 was not enough.
The 11/73 has the added I&D bits where 11/23 only has user registers and
MMU.

<years, and it was installed on the same machine almost as long before I go
<it. Present setup is 11/23, 256KW, 2 x DLV11J, RLV11 + 2 x RL02, RXV11
<workalike, IBV11, BDV11.

<Allison, can you remind me what you did to make it work on an 11/73?

You and Tim Both helped get it going as I could not make at that time the
pack needed. I don't run it often as Unix is less than really interesting
to me but being an RL02 pack I can run it on a whim.

Got it onto a RL02 pack. It's the supnick emulator V7 binary image for
RL02 and it will run from RL02 IF the pack is a RL02k-DC (no defects).
The reason for that is the image is for a theoretical perfect disk and
it's bad block map is zero defects.

The hardware is 11/73(KA11J-A), 2MB ram, DLV11-F, DLV11J, RLV21/RL02,
RXV12/RX02, RQDX3/RD52(x2)/RX33, TQK50. It's a very stuffed BA11N box
with a CD/CD (18 slots) backplane.
