Re: [Simh] How to access RT11/FIles11 floppy images on Windows?

[Clem Cole]

there is a unix program called rtpip  we wrote in the 1970s   i can dig up
a copy but not for a few weeks as i'm traveling but if you google under
that name you might find it

Timothe, well spotted (I actually noticed the lack of $close when 
posted, and said, oh well... it does the job.)

However, remind me to never post any quick hack here ever again. :)

This was used to pull an image of the ROM, initially to probe the code 
with VMS PATCH, eventually to dupe the ROM. In the end, it was easier to 
just pull the ROMs and duplicate them.

I suppose you could, but why?  SIMH builds just fine on a Mac.  A ready to run 
installable package of SIMH would be interesting, that should be pretty easy to 
do.

Interesting, I’m pretty sure I had it running on Virtual PC on my Mac, probably 
close to 15 years  ago.

This reminds me, has anyone made a VMware appliance for either the PDP-11 or 
VAX using SIMH?

For OS X, you could give my program a try.



It's still early in development, but can handle RT-11 R/W, Files-11
(ODS-1, not ODS-2), RSTS (RDS-*), DOS, XXDP, all R/O.

Paul has a utility that handles RSTS R/W.

Years ago I reconstructed an RT-11/Fuzzball disk using
dosemu + dosemu-freedos + PUTR. It didn't work interactively
and resorted to creating an indirect command file called putr.ini.
Running dosemu putr.com then did  the job.

Ok,

 

I got and installed DOSBox 0.74.  I tried to access my RT11 disk images but 
PUTR hung up after entered ‘mount rx0: image.dsk’.

 

With /RT11 option, it successfully mounted but…  I tried to access directory 
(dir rx0: ) and it hung up forever…

 

I can’t kill PUTR until I pressed CTRL-F9 to kill DOSBox.

Run it in a DOS VM.

Re: [Simh] VAX 8200

[Timothe Litt]

Even though someone found a utility for the 8200, a program like this is
handy for other machines (and device roms).

A good outline of the essentials of PFN (and file) mapping, but for
general use...

You neither compute the checksum hinted at by "format" (and "buffer"),
nor do you $FAO or output it.  Also, the movw @ 40$: (and the /2 above)
may  want to be movl /4; most VAX do longword fetches for i-stream; as I
mentioned previously, word reads from I/O space may or may not be
supported on a given platform/address.   Note that the "checksum" is
more often a CRC-32 than a 16-bit quantity.

You don't need $iouv2def for this,nor lib.mlb.(I expect that you
borrowed code from something that did.)

I recommend an explicit $close of the file, which can provide the exit
status.  And .BIN would be a better file extension than .exe (since
you're not writing an executable file.) 

Finally, the count at 40$ -1L and the 'page_count' symbol ought to be
functions of something like "rom_length" so they stay consistent.  e.g.
rom_length = ^X1; page_count = /512; loop_count =
rom_length / (2 or 4);

Have fun.

Um, fair enough.  I don’t suppose someone has a program already 
written to do this?


  I could have easily done that about ten or fifteen years ago, and in 
theory I still can, but it’ll probably take an afternoon with the VMS 
manuals to remember how J


Here's an example, which I wrote for the MicroVAX. Took me a bit to find 
this.


The program creates a file called ROM.EXE and copies the boot ROM into 
that file.
Note the "vbn=#<^X2004/512>"  line - that 
says that the ROM is mapped into physical address 2004 on that 
system. Likely different for others. Size of the ROM is calculated by 
the "page_count" variable.

[Simh] How to access RT11/FIles11 floppy images on Windows?

[Tim Stark]

Folks,

 

I googled and found PUTR utility but it is for PC-DOS systems only.   Does
anyone know similar utility to access RT-11 and Files-11 floppy images for
file extracts for other platforms (Windows, Linux, and OS X)?

 

Thanks,

Tim
