Agreed.  The SIMH logic is that the container file addressing matches

the RX50 case, that is "logical order" because the MSCP controllers work

controller works that way.


I think the bare image files should always be in physical sector order. As 
you state it, it's the MSCP controller that rearranges the sectors into 
logical order. And thus, the MSCP emulation in SIMH should exactly do that 
when emulating a RX50.

Is it possible that there is a Linux version of ImageDisk?
I found a signature "IMD Linux 0.19" in the P/OS images from
ftp://computermuseum.informatik.uni-stuttgart.de/dec/pro3xx
If so, could you please provide a source or link for the said software?
Thanks a lot!

If you want to copy raw floppy image files to the device, a simple "dd" command 
will serve, if you first use fdparm to set /dev/fd1 to 10 sectors per track.

Paul,

Doesn't .IMD format have extra headers and metadata that means you can't
just dd it to the raw device?

I have no idea, I know nothing about IMD format.   Is there a spec?  Is it open?

This is why I put them up in .imd (ImageDisk, it works on DOS) and .img 
(image). Oddly enough I went to install SPSS/X on xHomer and it blew the 
emulator sky high (crashed the "Pro"). Then I put it on my real 380 
running 3.2. It installed but when I ran it the program displayed the 
opening page (bitmapped, worked on Xhomer) then wanted Disk 3 in drive 
0. Well, then it wanted it write unlocked (no way on a install disk), so 
I used Imagedisk to write a copy, popped it in and with a quick "access" 
it started the program and now it doesn't need the disk.


At a files-11 level there are no changes but I'll bet if I dumped that 
disk and did a DD: I'd find that the program hard wrote something to 
some sector with the serial number of my Pro. So it couldn't be 
installed in other places. I wonder if xhomer emulated the serial number 
register on the Pro/350, maybe not and that's what blew it up.


Still, it works, and it was fun to fiddle around a bit. Really nice to 
be honest.

Yes.  A three letter company I worked for and another large company in 
San Diego  would send out less obvious emails and if you clicked on 
them, would get remedial invites to training.


BTW, these are pretty simple to navigate with lynx.  I downloaded a 
pretty subtle one some time ago and unpacked the payload.  Fun things I 
didn't follow, mostly sucking in other stuff from other sites.

This sounds suspiciously like something I think was called Prolock or 
such.  Used screwed up disks, usually as the boot disk with a signature 
to enable the final bit of install.  Copywrite (I think it was) which 
did bit binary copying with timing on the disk could copy them.  Even 
had some things to align with the high track bit offset of the defect.


A company I worked for bought them  but didn't study the usage manual 
and ended up with disks which could be copied by dos copy command, then 
write protected.  The genuine ones had to have the write protect 
removed.  The disk error from the write protect caused it to think the 
read of the protected part of the track was successful.
