Are you looking for a replacement of the Hewlett-Packard HP15C calculator?
Then look no further, check out the following replacement I found, its the DM15L from swissmicros
I had the HP15C for years and I can not find it, I searched everywhere. So after looking at eBay, Amazon and so on with these prices for a 30+ years old calculator, I started looking for a replacement and a good friend of mine just said “swissmicros”. Well I looked it up and found it. 2 Days later it arrived in the mail.
To setup the time & date:
[SST] +[ON] (start time/date adjustment) , use [/], [x], [-], [+] to change and [ENTER] to set
Currently in December 18, we adjusted the clocks in the house (Spring forward, Fall back)
So for the calculator I checked [A]+[ON] and the clock was 1h ahead. Easy to fix: Just hold [STO]+[ON] to adjust the time “-1 HOUR”. You can also repeat the Step several times if needed.

Here a few special options
There are several websites that show you how to program this little calculator. Did I mention that you can program the DL15L the exact same way you did with the HP15C.
