HP82143 emulation and virtual HP82153

[Jurgen Keller]

I'm also a big HP-41 fan and I like the barcode reader as well. Also a nice device for demos! Recently, I've created a video about printing barcode on a Thinkjet printer and on a plotter.

Your SCDEMO application looks to me a bit like what Martin Hepperle did:
A Software Decoder for HP-41 Barcodes

But maybe I've missed the details. Anyway, enjoy the project and let us know of your progress.
