I can't remember for sure, but I think there were eight SSDD (RX02)
floppies
plus an Auto-Install floppy. That would have been for V05.06 of
RT-11 which
requires over 6,800 blocks for an RL02 disk pack. Since some of the
files
get duplicated, eight seems about right.
I doubt that V05.07 of RT-11 from Mentec was ever supported on RX02
floppies. The size of the binary distribution for V05.07 of RT-11 is
over
16,600 blocks on an RL02 disk pack of which over 9,000 blocks are
DSK files (one of which is 7,000 blocks) which Mentec added to the
V05.07 RT-11 distribution.
Using RX01 floppies will take many more since there are only half the
blocks
or 494 blocks on a SSSD (RX01) floppy.
Do you have any other questions? I don't know of any RT-11
distributions
on RX02 image files for either V05.06 or V05.07 of RT-11. There may
be some for earlier versions.
The first one out of the box read 1/87 and its not the date.
Can you provide a DIR of the first few floppies? The names and
sizes of the files will pin down which version of RT-11 if the
actual dates were not correct. Otherwise, the dates of the files,
if they are correct, will specify the version of RT-11 if the dates
are 1983 (or after) when V05.00 of RT-11 was released. Before
1983, there were many updates, so there is more confusion.
Internally, each SAV file has a version and each MAC file also
has a version number which will also help identify the file aside
from a BINCOM to compare two files.
