Always a joy...
The "labelless" HP17B is the most interesting of them all, for me.
Once again, thanks for sharing.

Thanks Luiz,
I have also added HP19C and rare Seiko MC-2200 recently. Also a prototype HP33E - which has a "0000" serial number. Keith

As for the Seiko, they had an interesting programmable watch, which surely qualifies as a pocket computer as well: Seiko UC-2200
It even uses wireless (inductive) data transfer!
