Hook up a LED to the battery connection. Since the LED will only light when
current goes from positive to negative, it should be no problem determining
which side is which.

BTW, that doesn't look like you posted an

Obhack: Using a hex editor to make windoze display my name on the window bars.
Just kidding, I hate when people post crap like that :)

Obreallymyhack: Writing a "multitasking" copy program for the old
1541 drive
for the C64(actually, I had a 128).  Basically, the copy program sat in the
limited RAM on the drive, while I whiled away my time on the modem.  How did I
get both to programs to execute simultaneously?  By using the built-in monitor
on the 128, I manually changed the code of my terminal program so that instead
of changing the color options (something I used once, then never again) it
vectored to the code that loaded my copy program onto the drive. Needless

it took a long time to do this and I felt really stupid for not just using a
file editor.  Plus, it's a million times easier to use an assembler that allows
macros and labels.  I guess the only real benefit I gained was the fact

command returns the pid(s) correctly, but kill says "too few
What am I doing wrong with this line?  I have circumvented the problem by
using a temp variable, but that's not a very pretty hack.
