I've seen suggestion that TU-58s are emulated in simh on
PDP-11s. However, I'm not seeing it in a show dev and my
google-fu is failing me to find any info on how to use it. Any
pointers on how to boot from a TU-58 image?
TIA,

Using simh v4.0 from github, in the PDP11 simh ini file:
*set tdc enable**
**attach tdc0 tu58.dsk*
then assuming tu58.dsk is a bootable image:
*boot tdc0*
Only two units 0,1 are supported (just like a real dual drive) and the images
must be 262,144 bytes in size (like a real tu58 cartridge).

The boot for RT-11 would be BOOT DD: the tape image should be built

Least that how it works for my physical PDP-11/23 RT11 system.
Generally all the files that should be on
a RT11 floppy needs to be on the tape.
For other OSs it first has to fit on the device and have a suitable
driver for TU58.

RT-11SJ works running from TU58, but just barely, and it is not really usable.
RT11 is barely usable once you move up to a dual drive RX02.

Well, I can't agree with that. I used an LSI-11 with 4 RX02 drives running
RT-11 to develop COBOL programs back in the early 80's. It was slow, but
that is what coffee breaks were for.

IF you set up RT-11 XM and have an 11/23 or larger the memory over 32KW
can be used as a virtual disk.
The process boots using Tu58 and copies to VM and set the boot device as
XM and then boots XM. The
com file basically copies the tape to VM then configures the boot for XM
and the boots it. Then the tu58
is free for use as storage and to add programs to VM. The down side is
a boot is about 5-8 minutes but
once VM is up and booted very fast and useful.
I've done this in a BA-11VA 4slot with 11/23cpu, 256K ram, MRV11, DLV11J
and the TU58 stacked above it.
The result si 192K of VM and two drives. Its compact as PDP-11s go and
actually runs useful programs.
An enlarged system is a DEC 12 slot dual width Q22 cage with 11/23 cpu
(M8156), 2mb of ram (M8059),
and a MRV11 (Carries boot roms) plus DLV11J. The roms are copies of
11/23+. I enjoy playing with real
hardware.
I have larger BA11S boxes with 11/23, 11/23+, 11/73 and a ba23
microPDP11 as test systems and working
systems with a full array of disks, floppies and the only tape that
seems to work the TU58 (don't mention
the TK50, please).
The only PDP-11 sim I've used is John Wilson's Ersatz-11, its very good.
