I'd rather wish that Christopher had worked on his NP41v3:

I saw this on the FB HP Calc Fan group. It was hard to decide which one to buy, the one with the bubble LEDs, or the much cheaper one with modern LEDs. I still haven't decided... but will probably go cheap on this one...
Nice article, thanks for posting! Chris' builds are charming and ingenious.
