Re: Memories... @IMG
I had the first Sinclair programmable calculator... that I bought with money from my first after school job!
My math teacher & I had great fun writing programs to do all sorts of fun (but otherwise) boring things. It was so "revolutionary" it was actually allowed into my math higher exam -- calculators were allowed, and no-one had thought to restrict programmables yet!
Helped me get a few, otherwise dodgy, points in some areas!
