Again, I don't really have much experience with RT-11. Is it possible the disk image
has drivers for the disk system (which you don't have) and is crashing? Jerome Fine
is the expert on RT-11.
Jerome? Any ideas?

Subject: Re: Which RT-11 for an 11/03
Gary, et. al.--
Ok, I spent some time trying this again, and here?s what I did. The system is
very basic ? LSI-11 CPU, 32kw of RAM and two SLU cards. Using PDP11GUI
and TU58em emulator. XXDPD2D tape image loads and runs properly with
this configuration and the standard boot loader.
Based on the instructions on Malcom Macleod?s site, I prepared an RT-11
TU58-target tape image from the base RK05 image from the SIMH
distribution. The key incantation is:
COPY/BOOT:DD RK0:RT11SJ.SYS RK0:
What this should do is make the disk image bootable as a TU58 image.
Next, I fired-up TU58em, loaded the boot loader into the H11 and ran it.
Here?s the log from TU58:
D:\DEC>tu58em -v -p 3 -s 9600 -w rtv4_dd.dsk >>log.txt
info: unit 0 rw file 'rtv4_dd.dsk'
info: serial port 3 at 9600 baud
info: TU58 emulation start
info: R restart, S toggle send init, V toggle verbose, D toggle debug, Q quit
info: emulator started
info: boot unit=0 blk=0x0000 cnt=0x0200
info: read unit=0 sw=0x00 mod=0x00 blk=0x0002 cnt=0x0800
info: read unit=0 sw=0x00 mod=0x00 blk=0x0006 cnt=0x0400
info: read unit=0 sw=0x00 mod=0x00 blk=0x0008 cnt=0x0400
info: read unit=0 sw=0x00 mod=0x00 blk=0x000A cnt=0x0400
info: read unit=0 sw=0x00 mod=0x00 blk=0x000C cnt=0x0400
info: read unit=0 sw=0x00 mod=0x00 blk=0x0134 cnt=0x0A00
info: read unit=0 sw=0x00 mod=0x00 blk=0x0085 cnt=0x0132
info: read unit=0 sw=0x00 mod=0x00 blk=0x0086 cnt=0x3CC8
At this point, the RUN LED goes off and the system halts. It looks like the
boot loader is loading and running the second-level loader on the tape, but
something happens after that. Not sure where to go from here.
Thanks all!
