Thread time once again! A Package from a fine fellow in Valencia! The contents are something I've been trying to find for quite a bit now. A bit more expensive than what I'm usually willing to spend, but this is special. #ポケコン

Random side note: It would seem that Lidl Spain had a sale on Milbona products back in March. I hope the Spanish among you had a chance to grab some cheap dairy goodness. Also, nachos.

Well, there you are, my little lovely! I hope you had a nice & gentle journey.
Apparently, you did indeed! Mates, I present the #Casio fx-5400p, the scientific calculator brother to the PB-80!

Thanks to @ledudu, I found that there was a calculator version of the PB-80 series, the fx-5400p. Since then, I've been looking for one high and low. Recently, I managed to bag the manual from a US seller, but I didn't have much hope for the unit itself. #ポケコン

And then I get an ebay notification for an fx-5400p. I've been looking for almost three years and finally it shows up! #ポケコン #fx5400p

Compared to its brother, the fx-5400p comes in an identical clamshell case, but different colour scheme. The LCD module is not shared between models, reflecting the extended modes the 5400 has to offer. The dot matrix on the PB-80(bottom) is also decidedly more slanted. #ポケコン

The keyboards are multifunction membrane affairs & as good as those keyboards get, a buzzer mode can give acoustic feedback for input. The fx-5400p has more functions per key & those extra modes are accessed via the EXT, ALPHA, SHIFT & VALUE keys. #ポケコン

The number pad on the #fx5400p also gives you access to the same physical constants that the #FX750P has. #ポケコン

Sadly, you lose the memo function (mode 9) on the fx-5400p. I guess the extra math functions needed space. The BASIC on the fx-5400p gets added math commands lacking in the PB-80. Although it has a functional piezo buzzer, the 5400 doesn't understand BEEP. #ポケコン

RAM size on both units is a paltry 544 bytes. This can be expanded via a 1 KB OR-1 RAM pack. Sadly, both models have no I/O ports for a cassette recorder / printer. Casio dropped the ball here. This would've been a perfect tiny lab computer otherwise. #ポケコン #fx5400p

The PB-80 is already my favourite of the small factor Pocket Computers. The fx-5400p is the icing on the cake. The well protected unit with the added math functions, the programming capability plus the budget pricing would have made this my choice in the 80's.
