I will shortly be making some copies of the CD images from:
ftp://ftp.trailing-edge.com/pub/cd-images/
that I have downloaded and wish to offload from my hard
disk drive. I have verified each of the 2 RSX-11 and the
1 RT-11 images against the MD5 values in the file MD5SUMS
and they are the same. In addition, after I copy the image
on my hard drive to the CD, I will verify them against their
respective images in their hard drive files. To do so, I
will be using RT-11 and BINCOM (with some of my own
modifications which allows me to also verify block 65535
at the end of each RT-11 partition). Since there are a
maximum of 20 RT-11 partitions on each CD and each
BINCOM run takes me less than 30 seconds, the whole
comparison can be done in less than 10 minutes - which
will probably be about the length of time it takes to make
the CD copy in the first place.
Since there might be a number of individuals who can't
download at a reasonable speed (even with DSL it takes
about 12 hours each at about 30 KBytes per second as
compared with about 3 KBytes per second on a dial up line),
I am prepared to make additional copies (Tim Shoppa
no longer seems to have the time to do so) and make
them available at my cost of about $ US 1.50 (for media,
label, envelope and shipping carton - the media portion
is less than half of that total) plus postage.
By the way, for myself, I would VERY much appreciate
being in touch with all individuals who have a copy of the
RT-11 Freeware CD V2.0 so that we might exchange
information about RT-11. Tim Shoppa felt that he might
be violating privacy concerns if he made the names, of those
who ordered the CD, available. I don't see it that way, so
if you want your name to be known along with the other
individuals (or not as the case may be - i.e. restrict that
you have a copy of the RT-11 CD to ONLY specified
individuals such as possibly just myself) so that you can
receive interesting information about new developments
in RT-11 and the status of the operating system, then
PLEASE contact me so that we can share information.
Also state if you want to be known to the entire group
of just to specified individuals.
PLUS, as for TSX-PLUS, I am going to try again to knock
at the door of S&H to see what they may consider for
hobby users.
Sincerely yours,
Jerome Fine
