And the Sharp E500 and E550 maybe. But of course all these are precious antiques now which can't be purchased in a stationary shop round the corner. With a little patience they can be found on the internet for small money though.

I could get hold of an E550 but it looks like I'd have to write some software to do what I want. I could do that I suppose although the TI-89 looks easier, especially since I already know 68k assembler.

The main thing about the TI is that it has the function keys. Without the function keys you can't really do one-press SI units.
