### 5/5 — Authentic (updated)

*2024-11-22*

Very well done. The layout at fist glance can fool you for the real thing. As far as I am able it is an exact replica of the ti57, even down to the original calculation speed if you select that. Currently I’m testing out some of my programs I wrote in the late 70’s to 1996.
Easy to use and of course no key bounce. Ah nostalgia.

Update: The “behind the scenes” updating features have been fixed, which makes editing a breeze.
