That's odd that there were no images available with the Supnik emulator; I'll
check it out to see where they put them.

Here are two small disk images which you can test on whatever platform you 
have available -- either a real PDP-11 or emulated; I am not sure what 
emulators are specifically available for the Mac; however if you have OS X on 
your Mac then it's Unix based so you should be able to use the Supnik emulator
and maybe E11's Linux version.  Due to the file size I can't e-mail it, but 
you can download it from this link:

http://www.eskimo.com/~nickz/rsx11m/images.zip

(I assume you can read a zip file on your Mac via later versions of StuffIt)

contains two byte-for-byte disk images:

1.  5 MB RSX-11M V4.2 bootable image

rsxsmal.dsk - boots into console & DCL; after logging out you can
log 1,54/system to get back in (to MCR).
RSX11M v4.2 with Russian utils on 5MB disk.
DCL SET DAYTIME or MCR TIM accepts 21st century dates but day of the week is 
off since 29-Feb-2000 -- I've got a patch for that somewhere.  Also the 
existing startup.cmd file won't accept your date input (this RSX doesn't read 
the TOY clock), so under E11 you can type TIM and hit F12 to give it the 
correct date and time (e.g. 16-Feb-06 or 16-Feb-2006).  Some utils in [1,54].
PIP (version M2000) is Y2K compliant and has the optional /Y4 switch for
4-digit year output. Other utilities work (RMD is fine) but some have
cosmetic issues (e.g. MAC LST output would have 16-Feb-:6 for the printed
year).

2. RSX-11M-Plus V2 on 13 MB disk (distribution disks with full source were
about 54 MB total).

rsx2.rk6 - it's an RK06 so under E11 one needs to mount it as DM: to 
make E11 emulate an RK06.  Disk originally had P/OS V2 on it, thus the volume 
name.

TIM will accept 16-Feb-06 but not 16-Feb-2006.  PIP is original M1600; no /Y4.
More utils in [1,54] (grep etc.).
[200,2] = RSX SIG newsletters in runoff format; DRKULA.MAC in [200,3] is from
that.  [1,2] looks complete as to help files.

Fortran-77 in [3,54], also QIOLOG which is a simple disk editor -- listed
e-mail is outdated; RUN $qiolog then NL: or a filename to log output, then
choice 4 for the currently emulated disk.  Read in a block, then you can edit
it bytewise or wordwise, calculate checksums or zero out a block before
writing it to the same or a different location.

login is [1,54]/camac

If you're able to read these then I'll see about making more comprehensive 
images available (these images are both abbreviated to keep the image size 
down but are fully functional); e.g. later versions of M-Plus with more Y2K
patches applied.
