SwissMicros, when are you going to make a DM-01? There seems to be considerable interest...
DM42- clock losing time
Re: DM42- clock losing time
What is the metric tensor in imperial units?
Re: DM42- clock losing time
Well, the chip (not cheap!) is already here (http://www.panamatik.de/html/hp-01_repair_kit.html).
What we need now is a modern titanium case and we are done!

Accurate +-3ppm time with temperature compensated quartz. Full calculator capability,

Re: DM42- clock losing time
... but of course, a potential future DM-01 should be RPN (ducking for incoming RPL flak...)!

Re: DM42- clock losing time
I could concur, in this case.

Re: DM42- clock losing time
My test has run long enough to show results:
DM42: 13 s fast after 88 h = 41 ppm
HP-50g: 3 ¼ s slow after 50.3 h = 18 ppm
The DM42 is a beta unit, SN 62.
I do have a data logger recording temperature and humidity in the same room, so I could provide those numbers if necessary. I didn't keep track of radiation levels, though.

You are strangely quiet about the placement of the arithmetic operator keys...

Re: DM42- clock losing time
Bernhard at Panamatik has already created the board for the HP 01. Only thing is it needs the LED block from a donor HP 01. Now if someone could create a case and LED tech for the Panamatik board.
Always wondered why there is no Apple Watch app simulating the HP 01. Maybe making a scientific version of the watch! Bernhard has stated that he can code the HP 01 board he has created (I have two) into a scientific rpn version but how does one create the overlay?
I too, would like to see an RPN LCD Scientific version of the HP 01. HP actually had and LCD version prototyped for production but it was cancelled.
