• Slanted LCD

Model: TI programmer II lcd
Battery: 2 x LR44
Adapter: 
Year: 1985
Chip:  TPO456/CD4569
Info:  If you take your time comparing this calculator with all other members of the second slanted series (BA-54, TI-57-II) you notice something very special. The keyboard position doesn't fit to the usual spacing. The ON/C-key is misplaced and one key is super-sized. You have to open the calculator to get the answer:  This is not the usual construction of a slanted calculator! A very small printed-circuit-board, actual the form factor of a modern slimline calculator like the BA-II, is fitted into the housing.
