Keystone 2050
1974
Logic Technology: LSI

A rather rare early scientific pocket calculator. Unfortunately, this unit is non-functional, seems to be a non-repairable fault with the calculator chip.

AGS 14

Logic Technology: LSI

Novus 6010 "International Computer"
1975
Logic Technology: LSI
Display: LED

Canada made the transition from Imperial measures to Metric in the 1970's. All sorts of conversion aids were produced: tables, 'slide rules', and a few specialised electronic calculators such as this model.

The Novus (made by Philips) brand calculators suffer from poor quality displays which tend to lose segments, as can be seen in several digits of this unit.
