My personal calculator history

[peacecalc]

Hi all,

with 16 yaers I got may first calculator a canon palmtronic F-52 with a LCD display. That was in year 1977. I lost that calc and as I was looking for that calc forty years later (for buying it as a vintage calc again), I had to realize that this calc is a very rare vintage calc. I only saw since I was looking for, only one offer at ebay (with a bleeding display). In the year 1982 I began the studies in physics at the university. I was looking for a calc with more possibilities and I found the HP 15c. In that former times in germany the calc had cost 400 Mark. I got it cheaper for 300 Mark. This calc works until today and was a lot in use.
While my profession I was looking for a more ease of handling calc and found the HP 32II. Since 2010 I use the HP 50 the direct opposite ease of handling, but with a lot of joy in programming in User-RPL. The most wired program I made was able to unwrap hulls of 3d structures into 2d.
And now I use th HP Prime G2 since two years.
I'm not a real collector more a playing child which is curious about that calcs. I wasted a lot of money and a lot of time more for this kind of activity, but to be honest, with a lot of fun!
