After a long wait I finally obtained an 80-column HP-IL interface for my 71B. For analog video I use a video capture USB dongle on my Mac Book Pro. It works great with the 32-column interface and the 80-column in 40-column mode, but in 80-column mode it looks terrible. However on a CRT TV it 80-columns looks readable. It's been over 20 years since I've seen 80-column video on a TV (Apple ][e, IIRC). IIRC, it never really looked that crisp.
What are you all using for your 80-column output device? Have any had luck with video capture devices?
Thanks.
P.S. I forgot to add, that is looks a bit better in PAL mode with video capture.
