I seemed to
recal being able to reset all the passwords via the menu
system so as long as you could get in you could reset all the passwords.
Correct, I seem to remember that TUTOR, ADMIN and INSTALL would get you
into any machine that hadn't had the OS fixed. One of mine has the OS
fixed and I still haven't figured out how to get into it but I haven't
tried very hard either since I have two with the "broken" OS.
You could also boot a systems disk and mount / . Once it was mounted you would
use vi to edit the /etc/passwd file.
Oh, I also
still have the 8 head mods to the hard drive system. You would
swap in a 2010 for the WD1010 and solder on this mod to get the extra head.
Replacing the WD1010 with a 2010 allowed you to use a hard drive with 8
heads and a resulting larger capacity. I think there were also some mods to
increase the data transfer rate too. WD2010s are widely available on
surplus/scrap disk drive controllers. This mod and many others used to be
posted on the net. I think I have them all archived, let me know if you
have trouble finding them and I'll E-mail them to you.
As some else pointed out, the WD2010 got you the extra cylinders (2048)
the other mod (a pal, which I have) got you the extra head bit.
BTW: I also archived various messages (dead tree format), I also have the
hardware manual.
