I have been given a PDP-11/44 and I was running through all sorts of
diagnostics to check out the machine. It seems to work fine except for the
trap test KKABD1 which fails at 23252.  It passes an earlier version of the
same trap test.
The listing (thank you Jörg) is at: ftp://u58104846-pub:open4you@

It tells me that my M7098 board is missing ECO #7. Anyone knows of a list
of ECOs for the PDP-11/44. I think I have searched everywhere I can think
of but haven't found it.
