That's a weird calc! I guess the chip is just a VFD TMS1000, so that will be easy enough.

I got a TI-1031, but it has a TP0311, which datamath.org says has a one-bit serial adder. So probably too much work.

I also got a Tandy 2-Player Football with a PIC1650A-144, a Tiger 7-in-1 Sports Stadium with a TI MP7304 (probably TMS1400), and a VTech Talking Play-by-play Baseball with a glob and an SP0264.
