Or why not use the dc command instead and get the good stuff (RPN)  ;)

My new calculator. A HP-48G. The PC-1500 and plotter did not work. looked great but nicads and batterys had leaked and did severe damage. The 1500 gives some image but the 3,7Vdisp. is not more as 1.5V and it draws 25mA even when powered off so something is wrong. If it was not all the battery damage I would give repairing a try.

And just finnished repair, a HP-9100A, I have also a 9100B here but that is in very bad shape, faulty HV (Q1 dead), fautlty PSU, missing CRT, non functioning processor, lots of damage by salt water. Probably not fixable. Both are not mine but from a museum.

Been fighting with Korad power supply, no matter, long story short - I need to increment 0.009A with 0.001. Well....... guess what (this is python):

>>> a=0.001+0.009
>>> print(a)
0.01
>>> b=1000*a
>>> print(b)
10.0
>>> print(int(b))
9

(I know WHY this is but really, pretty shocking).

I started with some really old HP/TI calculators - brown plastic with yellow gold lines, led disiplay.

Then some Casio VFD calculators. Then FX-80/82, Sharp EL502, some Casio programmable, ...

Now, I am on 12C - love it.

HighVoltage:
The calculators I use most often are:

1. HP 32S II (RPN)
2. HP 15C  (RPN)
3. Sharp PC1350 for fast programming with good size display
4. Sharp PC1600 for more advanced programming and 4 color plotter.

The Sharp PC's are connected to the laptop via RS232 and all programs are stored.
Anything more complex is done on the PC
