Good evening!
Recently, I was able to fish this thing out of the bay:
According to a website that google found for me, it is the first talking pocket calculator, a "Speech+" model from Telesensory Systems in Palo Alto, Ca. Inside, it has two large circuit boards full of bad evil chips from Texas Instruments, but the housing looks very HP like: The same kind of plastic, dark brown colour and texture of some HP models.
And even more HP like is the pouch of unusual size 21x15cm or 8x6in: Same colour, same material and it even has the inner pocket of many HP pouches (used here to hold an earplug):
So I'm wondering if this manufacturer was related to HP in any way? Google and Wikipedia couldn't help, but maybe someone on this forum knows more?
Regards, Max
