This is some serious 80s productivity right here.

@Cloudscout Is it a real setup, no emulation?
@lnxtx This is an original Mac Plus with an original Radius Full Page Display upgrade.
@Cloudscout @lnxtx - so how did this work? The Mac Plus only had a SCSI port and no PDS slot. What was driving the second display?
@theirongiant @lnxtx A daughtercard that plugged into the CPU socket.
@Cloudscout Wow, you’ve got a Radius Full Page Display? I’m jealous .
@Cloudscout first time I’ve ever seen a vertical CRT. So cool!
@illogical_me Probably the most known machine with a vertical CRT: https://en.wikipedia.org/wiki/Xerox_Alto

@Cloudscout I remember hearing about people who had two monitors back in the day. On macs! I was convinced that they were rolling in money.

I shudder to think what this setup would have cost adjusted for today's dollars.

@Cloudscout
Nice!
I never had a Radius on my Mac Plus, but when I got a Mac II, I got the Apple Portrait Display. It didn't do rotation, but it was great for coding and word processing. I kind of miss it, even though my modern 32" 4K LCD monitor is arguably better in every way.
Has anyone made a NuBus graphics adapter that can do 4K?
Given that classic MacOS didn't know about high DPI monitors, maybe running at 1080p (2K) would be better anyhow, so same question for that.
@Cloudscout Ohhh! I had a setup like that with a Mac SE in my first "real" job. It was indeed cool.
@Cloudscout Had a IIci with a COLOR Radius Pivot at this one job.
@david I had one of those on my 4400 back in 98-99. I regret getting rid of it.
@Cloudscout It was really cool, except whenever I had to move it. OOF.
