I have an issue with moving a RSTS/E v9.6 setup from under SIMH to the real hardware equivalent.
My setup is an 11/44 with full 4MB memory, DZ11, DL11, DEUNA, RX211, and an MSCP disk controller. All the devices are 'exactly' the same between SIMH and the real hardware, except SIMH models an MSCP UDA50, and my 11/44 has an MSCP Emulex UC18 dual SCSI disk/tape interface. I can run the exact same 2.11BSD setup on each, as well as RT-11 and XXDP. RSTS/E however does not behave the same. It dies miserably on the real hardware.
On the real 11/44, after I boot the RSTS/E image on DU1, it runs for a moment, and then immediately fails with the following message:
which repeats endlessly over and over as fast as it can. The emulated disk is an RA81 456MB sized image running on a SCSI disk.
On my SIMH setup, I see quite different behavior. It boots and enters time sharing normally, and SHOW DISK indicates a valid cluster size (16).
I'm looking thru the available v9.0 documentation I have, but not have yet found the above error message and how to decode it (I'm not sure what cluster size it think thinks the disk has, and/or how it computes that).
Any ideas/thoughts appreciated.
