"https://retrocomputing.stackexchange.com/questions/3055/whats-the-story-behind-the-name-x11" showed up in the sidebar while I was browsing stackoverflow earlier and I noticed the question getting some high-signal answers, so I added a comment asking how to get X10 working, something I've been wanting to do for some time. I was recommended to open a new question, so here it is.
Many years ago while browsing xwinman.org I spied "xwm" at the bottom of the full list of window managers. It's listed as
Possibly the first... this dates back to 1985, before X11 itself. The version in the archive is from X10R4.
Naturally, there are no screenshots anywhere. It probably looks really primitive, but I'm curious to fire it up nonetheless and play with it for fun.
So, my question is, how can I get X10R4 running on an arbitrary modern machine running Linux (or Windows)?
Naïvely speaking, I suspect emulation would likely play a key role.
However, I'm not aware of any practically-usable Solaris/SPARC emulators, and I understand that X10 was a SunOS/Solaris-era thing - the history section in Wikipedia's actually-decent article on X shows that X hit version 11 in 1987, 4 years before Linux was announced (here :P).
X10R4 is noted as being from December 1986 - maybe there's (haha) an EGA UNIX for PCs from that era? (I'm woefully ignorant of UNIX history.) Or maybe... there's a PC-compatible VMS?
xwinman seems to have a bit of a permission glitch, but the xwm/ directory happily resides at the Web Archive (spoiler: it's a bare Apache index with a lone xwm-X10R4.tar.gz.)
I had a cursory look online to see if xwm was hiding in any browsable source repositories - and I found one! http://www.retro11.de/ouxr/43bsd/usr/src/new/X/xwm/ (Try not to DoS it)
Note: I can't create x11 or x10. Feel free to edit more tags in.
