It was a fruitful year for my small collection.

I was losing hope of finding a working HP 67 in decent cosmetic condition and at a reasonable cost, and this year I eventually found two of them in this state! This is certainly the acquisition of which I'm the most proud.

I also pruchased several non-HP calculators:
- Sharp PC-E500S with standard 32KB RAM, very cheap.
- Sharp PC-E500S with built-in 256KB RAM.
- TI 92 Plus
- TI Voyage 200
- Casio FX 9860G Slim (second one)
- Casio FX CG50 (I have also the white version: Graph 90+E)

To be complete, I should mention several slide rules in pristine condition (Pickett N3-T, Pickett N4-ES, K&E Deci-Lon…), and a very nice mechanical calculator Walther WSR 160 (the second one for me).

Happy new year Smile
