Okay - pseudo-newbie question - I know this has been

answer...
Where does one obtain the various .dsk, .tap, etc., files for E11?
FTP from somewheres? Toggle them in bit-by-bit using the "F" keys as
console switches?
And while I understand the 'hobby use' version does not speak "SCSI
Tape" - does this also hold true for SCSI 9trk emulating a TU77, or
similar?
Thanks all, and best of the Season!

First, you have not mentioned which operating system you
wish to run. There are easy locations to find for some of
the operating systems and others are more difficult.
Second, if this is for hobby use, you should really be running
any PDP-11 operating systems under SIMH - unless you have
a legal license to run the operating system that you are looking
for.
Be that as it may be, there are a number of .DSK files
(most of them are compressed via WinZip or at least
WinZip will UnZip them) available for download. But the
only ones I know about are for RT-11 and they are only
to be legally run with SIMH.
One thing I don't understand is why there is a preference
to use a .TAP file when an emulator is being used. I would
think that an image of a hard disk distribution which has
random access to all of the files would be easier to use.
In RT-11, that image file may be set READ ONLY or
WRITE PROTECT so that no changes can be made.
For an operating system which requires WRITE access,
first make a copy.
If you have more information, it will be possible to answer
specific questions.
Sincerely yours,
Jerome Fine
