HP 35s Checksum explained

[Thomas Radtke]

I'd have one if it weren't for those stickers. OTOH I don't need much beyond what my 32SII, which I use at home, can do.

The 35s in my office has the advantage of being capable to store *many* equations and programs, and still can integrate :-). And if it gets stolen it can easily be replaced.
