I was going to say there is a great article about the Sinclair Scientific here:

And then I noticed who I'm replying to...

Despite its flaws, this calculator was quite an achievement, doing everything it did with a ROM that holds only 320 instructions.

That calculator is a hack in the most positive and brilliant sense of the word. Crazy constraints required crazy solutions. Amazing!
