TI Minimath would be 40 this year :-(

Calculator collectors,

I was able to disassemble a rare Texas Instruments Minimath prototype this rainy (Upstate New York) Labor Day weekend and discovered a very, very old TMS0111 single-chip calculator circuit inside:

Really a pity that the Minimath never made it into production.

Regards, Joerg
