The Sinclair scientific, remade: A classic calculator was reverse engineered from the bare metal - [Hands on]

Was the Sinclair Scientific calculator elegant? It certainly was a hit, gracing the cover of publications like Popular Mechanic s after its release in 1974. Cleverly written firmware dragooned its limited processor, intended only for basic arithmetic, into performing way beyond specifications. This allowed Sinclair to sell a scientific calculator to countless folks who otherwise could not have afforded one. But it was also slow and sometimes inaccurate, provided barely enough mathematical functions to qualify as a scientific calculator, and was difficult for the uninitiated to use.

辛克莱科学,重制:经典计算器从裸机逆向工程 - [动手]

Sinclair Scientific 计算器优雅吗?它确实很受欢迎,在 1974 年发布后登上了《大众机械》等出版物的封面。巧妙编写的固件使其有限的处理器(仅用于基本算术)发挥了超出规范的作用。这使得 Sinclair 能够将一台科学计算器卖给无数原本买不起的人。但它也很慢,有时不准确,提供的数学函数几乎不足以作为科学计算器,而且对于外行来说很难使用。
