Noel,
I followed the thread you provided and I appreciate the direction.
estabur(who thought these names up, I know 8 characters is limiting, but
c'mon) is indeed the culprit:
if(sep) {
if(cputype == 40)
goto err;
I'm gathering (read still investigating) that the 411 header is read by
a loader and the call to estabur is made with a value for sep indicating
that it is a split I+D binary, then the cputype is checked and sure
enough, it's a PDP-11/40 and the error is generated.
Thanks,
Will

The problem is this, when I attempt to execute
the v6tar binary on the
v6 system (it works in v7) it errors out:
v6tar
v6tar: too large
That's an error message from the shell; the exec() call on the command
('v6tar') is returning an ENOMEM error. Looking in the kernel, that comes from
estabur() in main.c; there are a number of potential causes, but the most
likely is that 'v6tar' is linked to be split I+D, and your V6 emulation is on
a machine that doesn't have split I+D (e.g. an 11/40). If that's not it,
please dump the a.out header of 'v6tar', so we can work out what's causing
the
ENOMEM.
