I noticed that downloads of the ISO images for RT11 & RSX freeware from Tim
Shoppa's website are slowwwwwwwww.
I'm not sure if he has a really slow internet connection, or if he (or his
ISP) is throttling bandwidth (I suspect the latter). To provide for faster
downloads to anyone who wants it, I am copying the RT11 & RSX freeware ISO
cd images to www.classiccmp.org/PDP11
They should be up there sometime tomorrow morning, don't download them from
me before then or you're likely to get a partial image. And you can bet
you'll get more than 14kbps from my servers :)
Also, if you only want portions of the freeware CD's rather than the entire
ISO image, the entire contents are already at that URL in natural (non-ISO)
form to download individually.

Jerome Fine replies:
I found that the best time was at night when I was able to
obtain a speed of about 30 KBytes per second. At that
rate, each download took about 12 hours.
Also, MD5SUMS is important so that anyone who does
the download can verify the image that they have.
If you are using Windows 98, a version of MD5.EXE is
available at:
http://www.fourmilab.ch/md5/
click on the md5.zip link.
Finally, for those who don't have a high speed line or a
CDROM burner, I am willing to copy them for you. A new
estimate of the cost will be about $ US 4 / $ US 6 / $ US 8
for ONE / TWO / THREE CDs. It turns out that the mailer
cartons are expensive when purchased in small quantities
and only about 4 people have expressed an interest. The
price includes postage from Canada and is an estimate until
I check for sure at the post office. The old price did not
include postage and the mailer cost was underestimated.
If you have high speed internet access and a CD burner,
them it will be much faster to do it yourself.
However, if you already have the RT-11 Freeware CD
from Tim Shoppa, I would like to get in touch since
future
RT-11 developments might change the current picture.
Plus, I am an RT-11 addict and I like to help other RT-11
users.
Sincerely yours,
Jerome Fine

New subject: What's the best way to slurp up DEC RX50s?
What I would like to do is, with commodity hardware, not DEC hardware,
digest a large stack of (distribution) floppies. I don't care if
the solution is under Windoze or Linux. Either will work. I have
a Teac 5.25" floppy working in my former main PeeCee that dual-boots to
Slackware or Win98.
I have TELEDISK, I have PUTR, I can probably have anything else if
required. I did notice a 10-sector floppy format special-device
under Linux. Wasn't sure if dd-ing from that device would work
or not, especially with the single/dual-sided issue.
Yes, I could probably do this on DEC hardware, but that would entail
spending way too much time in the basement where the 8200 is and its
console RX50s. If I do this on a PeeCee, I can be doing other things
while the disks gronk (but BACKUP/PHYSICAL would make it easy).
Primary goal is backup - TELEDISK should do that. Secondary goal is
to produce image files suitable for use with simh and E-11.
Thanks for any tips.

I used to have a driver you could load under DOS called RX50DRVR that
would let you read MS-DOS formatted RX50's on a PC with a 5.25 1.2MB
drive. I don't have this program anymore, although it is possible I
might be able to search out a copy, and I don't know if it would be
helpful at all for non-MS-DOS formatted disks. If you're interested, let
me know and I'll see if I can scrounge up a copy.

RX50DRVR would actually assign a different drive letter to be the "RX50"
drive. So you could actually DISKCOPY E: E: to copy one RX50 to another.
DOS DISKCOPY doesn't care about the format, so I think you could
duplicate RX50's this way no matter what system format they are in.
Also, a program that makes images from disks (I think they are many, but
I can't recommend any specific one) might be able to make an image from
an "RX50" drive that would work in SIMH. I'm not positive, but in my
mind it has a strong change of succeeding.
Hmmm.... Now to figure out where that driver might be...

There is also a driver named RAINDOS which serves the same purpose. It
will, in addition, allow formatting an RX50 diskette.

The ubiquitous 22Disk will take care of CP/M formatted RX50's (also 512
x 10), but other formats might pose more of a problem.

Jerome Fine replies:
I realize that this answer is biased in favour of using RT-11, but that is
because I tend to use RT-11 as the solution whenever it is possible.
In my solution, you gain the advantage of using all of the tools that
RT-11 provides.
First, set up a small image of RT-11 files in a Windows 98 file which
be MOUNTed by E11. Normally, a 988 block file which E11 uses
as RX02 emulation or DY is sufficient for a job like you are doing.
Then use PUTR to FORMAT (actually Create and zero out) a
number of large empty container files which you will use to hold
the RX50 images. Since the hobby version of E11 allows a
maximum of 32 MBytes for both the DY and the DU container
files, probably a 60,068 block file which will hold exactly 75
RX50 images is about correct (and allows for the 68 blocks of
directory when you do the INIT). If E11 allows it, an extra
4000 blocks in the container file would accept 80 RX50 images.
The set up a file that inits E11 and boots from the DY as well as
MOUNTs the 5 1/4" floppy as DU1:
For each different set of 75 RX50 images, you will need to tell
E11 (use SHIFT/ENTER to get the E11 prompt):
MOUNT DU0: <Windows 98 container file>
Under RT-11, the command:
COPY/DEVICE/FILES DU1: DU0:imagnn.DSK
will then copy the RX50 to the next image file in DU0:
You might also want to (I ALWAYS DO THIS):
DIFF/BIN DU1: DU0:imagnn.DSK
You can probably use SIMH instead of E11 in which case I
don't think there is a restriction of the size of the files.
After the image files are set up in DU0:, you can do anything
you want under RT-11. Later, you can use PUTR to copy
the individual image files to Windows 98 and then to a CD.
REMEMBER that BEFORE you use PUTR to copy the
RX50 images out of the container file, SET COPY BINARY.
The key advantage is that under RT-11, the images files can
be compared and modified if need be. The disadvantage is
that each file name is only 6 characters in UPPER case.
If you have any more questions, please ask.
Sincerely yours,
Jerome Fine
