Hey, mel. It's josh franta again. Quick question on this response you
made... here (above) you say that you could connect a DC power source to
the calc even if it's above 6V. In my electronics class, we built a
AC/DC (12 volts) converter; can I hook this up to my calc so that I can
run my TI from AC? Also, I was wondering if you could recommend any
good (begining) electronics books to me, especially ones on digital
electronics. I've read a number of microprocessor books (to learn z80 &
68k asm), but I was wanting something more general. I figured you'd know
of some decent ones, since that's how you learned this stuff. Thanks.
