correction to Tandy football inputs: R5 Right Left Down Up R6 Score Status Pass Kick R7 -- -- -- Pro
Thanks, I fixed that on my site. I must have misread my notes.
I posted info on the Sharp EL-503 calculator- www.seanriddle.com/tp0320.html. It has a TI TP0320 like the Business Analyst II. Interestingly, the chip was mounted upside down; the pins were bent the opposite direction and the label was printed on the bottom of the chip. I guess that made routing the PCB easier, or maybe they laid out the PCB and then had to change the side that the chip was to be put on.
