Awesome! Thanks for typing that up.
Also, that is a pretty cool way to know how your system is doing when you
boot it up.
According to the manual, the inverse video on the 35
means that you have
a "jammed down key" that is being detected on startup. This may well be
causing the "41".
This may be caused by the broken 0 key on the numeric keypad. The keycap
is missing and the spring is hanging out the tube that the key used to be
mounted upon. At any rate I think you are right that the 4A is an

10 PRINT "HELLO WORLD"

customer support disk, learning disk, etc. if you need
copies. I also
