Jerome Fine replies:
First, I suggest that the question is the real problem.
A real DEC PDP-11 running RSX-11 uses disk drives
that have a LLF (Low Level Format), but the FILE
STRUCTURE is unique to RSX-11.
On a PC, the disk drives, IDE or SCSI, will also have an
LLF, but the FILE STRUCTURE is the one used by WNT
(sorry I can't remember the name).
The real problem is that in the DEC world, format refers to
the hardware while the FILE STRUCTURE is unique to
the operating system.
In the PC world, the LLF and the FILE STRUCTURE are
lumped into one word called "format" - which certain
unnamed companies use to preclude recognition of disk
drives which do not have their own FILE STRUCTURE.
In Windows 98 SE that I run, I get around the problem by
tricking W98SE, but I digress.
As mentioned, one way is by using Kermit - usually over a
serial line, but perhaps over ethernet - I don't know enough
about that aspect to comment since I chose a third way on
my PDP-11 system.
I use a SCSI host adapter (I have a CQD 220/TM) which
uses a Sony SMO S-501. I also use an Adaptec AHA2940AU
on a PC and run the Full Ersatz-11. There is also a second
Sony SMO S-501 on the PC. Up to 300 MBytes at a time
can be transferred to the PC.
You did not provide sufficient detail about cost or final usage,
so I can't help much more than these suggestions. Plus, I don't
know RSX-11 very well, although I do run RT-11 all the time.
PLUS, you did not say if you have a complete PDP-11 or just
the RL02 or other disk drive and maybe just the media. If you
have just a SCSI disk drive, that is actually an easy solution.
Sincerely yours,
Jerome Fine
