[Simh] R: Re: RSTS V9.6 install

Hello Brett, 

I fixed (or supposed to) the problem, converting the tpc in tap, with
the utility in simtools package. 
After the conversion, the error disappeared. 

Regards, 
Fausto

This is an issue that I've had with the distribution sets since V9.0
came 
out.  Prior to V9.0 all RSTS distribution tape sets were DOS format.
The 
V9.x and V10.x distribution (boot) tapes are a mixed format tape.  The 
record length error that you run into is BACKUP expecting to see an ANSI

label with 2048 bytes, but running into a 14 byte DOS header because the

tape has rewound to the start of the tape. 

The first 10 to 12 files on a distribution tape are DOS formatted files:

 Name .Typ    Size    Prot    Date      MS0:[0,1] 
MGBOOT.SYS       1   <155> 14-Aug-88 
INIT  .SYS     622   <155> 14-Aug-88 
ERR   .ERR      16   <155> 14-Aug-88 
SYSINI.COM       5   <155> 14-Aug-88 
BACKUP.TSK     113   <155> 14-Aug-88 
SYSGEN.SIL     608   <155> 14-Aug-88 
DCL   .RTS     115   <155> 14-Aug-88 
PKG001.MSG       8   <155> 14-Aug-88 
PKG002.MSG       7   <155> 14-Aug-88 
RSX   .RTS       6   <155> 14-Aug-88 
GETSYS.TSK      52   <155> 14-Aug-88 

Total of 1553 blocks in 11 files in MS0:[0,1] 

 Name .Typ    Size    Prot    Date      MS0:[1,2] 
DOS   .EOT       0   <155> 14-Aug-88 

Total of 0 blocks in 1 file in MS0:[1,2] 

The DOS.EOT file is an empty DOS header with (as I recall) 3 EOT
markers. 
This marks the end of a normal tape and the COPY function of INIT.SYS is

going to stop (without rewinding) once it gets to this point.  If you
are 
NOT in this "exact" spot once the SYSGEN.SIL is running, the install is 
going to cough when BACKUP tries to find the ANSI header for the rest of

the installation process.  This is why I've broken up the installation 
sets on the distribution tapes I've put online (that I made a decade
ago) 
into 3 tapes (such as V95BOOT.TAP, V95ANSI.TAP, V9LIB.TAP). 

The tpc formatted tapes that Al and Tim have put online DO work, you
just 
have to make sure you mount the tape correctly and that it doesn't end
up 
in the wrong spot:

When Tim and I get a chance to put some "toys" together, I'll probably 
break the V9.6 distribution tape into 2 tapes and change the format over

to tap.  Since SIMH does a good job of emulating just about everything, 
it might even be easier to just provide a bootable hobby disk with all
of 
the toys installed for those who would rather just run MicroRSTS ;-). 

At the time Terry and I were playing with these distributions, Terry was

using V9.6 and running terminal servers with LAT.  I was using V9.5 in 
production and making changes in all of the V9.x line, but I didn't get
a 
chance to organize the V9.6 distribution before other projects came
along 
that took me in another direction for the next decade.
