Have an unusual draw to the older NECs for some reason, as I do with the HP Vectras, but would love to see a photo of your fixed setup sometime if time ever permits. Maybe I missed the obvious somewhere but where's the link to the YouTube video?

MindThreat - Yes, I have quite a draw to them as of late. Long story short, in 2019 I had some personal wants to have a portable vintage setup so I did not need to be stuck to one room to play DOS/Windows games or use old productivity software on native hardware. What I wanted was a vintage laptop computer - or several so I have a few backups - that did not cost and arm and a leg, and any "Achilles Heels" were simple/easy to fix for my skillset. I probably should blog a post on that story since it's kind of a neat observation into the mind of a vintage computer guy, lol.

I have photos on my profile under media - but my youtube page is https://www.youtube.com/creepingnet/ - The Versas have been dominating my once mostly guitar oriented channel lately.
