"Font" for HP41CX display? - John Ioannidis - 05-31-2014 04:46 AM
Does anyone have the HP41CX font (or its subset, the 41C/CV font) in some machine-readable form? Preferably, ones and zeros for "lit" segments. For example, A should be 11101100100010 (or some such).
Context: I finally unearthed my stash of B7971 nixie tubes (if you don't know what nixies are, you are missing on life), and got a set of "smartsockets" from tayloredge.com. So what's left in life except build a 41 display out of 12 nixies (plus assorted neon lights for the dots and the comma).
Next step will be interfacing it to an actual HP41, but that's for another show
Thanks

Simply take a look at this article here on hpmuseum.org.

Not what I'm looking for. Parsing the .ttf file to extract the segment positions is harder than defining the font by hand!

Take a look at the "41cx.kml" file that comes with Eric Smith's nonpareil emulator. It defines which segments need to be lit for each display character.
BTW: I would love to get my hands on some B7971 tubes but they are way too expensive these days.
I have some of the SmartNixies from tayloredge.com somewhere -- I need to dig those out and use them for something...Brian
