Yes, this is a "shared library" version of the ACNT program which can be 
built with sysgen to
save some space in memory. IIRC, it is linked against some RMSRES.TSK or 
FCSRES.TSK
library loaded into memory.

Look into the [1,2]STARTUP.CMD file what is done there. It is possible 
that some TSKs have to
be installed first (INS cmd).

Things that can happen are:
- the ACNTRES.TSK is not contiguous (PIP [1,2]ACNT*.TSK/LI does not 
contain a 'C' in the line
- some of the resident libraries are missing/not INStalled (because on 
that turn-key application there were not required)
- the ACNTRES comes from a different OS version
- there are several versions of ACNTRES.TSK in the system dir, and only 
an older one works.

Was [7,*] also privileged? I am not sure anymore after several years. 
The point may be though that
the password file is actually owned by [1,2] - in this case you might 
not be able modify it from [7,21].

I had downloaded them, as well as the ones at John Dundas's site, and 
did not find corruptions. The files
at the Australian computer museum are large, though; the first thing I 
did was to compress them with an
Adobe Acrobat. There it should have been detected if they were corrupt. 
So I guess its you having some
transfer problem.

Hmmm, to sysgen a new system, the installation set is required. One 
indicator you might have sysgen stuff
on the system is the presence of some [200,200]SYSGEN*.CMD scripts, and 
the current configuration
should be in [200,200]SYSSAVED.CMD;*
