I might read past this line later to see what other inaccuracies lurk - the story of how Gary Kildall (the author of CP/M) missed out on a deal is well know (though everyone has their own version of events) as well as how Microsoft (already contracted to supply a BASIC interpreter) snapped up QDOS/86-DOS making, as they say, history.
But one thing is very clear - CP/M and DOS are nothing at all like Unix 
Thought that might inspire you to comment @anon88169868 
This blog type post from 2001 has some interesting pointers too
Brings back memories of Night Mission Pinball, Wolfenstein, and Jill of the Jungle!
Also not forgetting Adventure which I believe was ported from a DEC PDP-11
RANT!
As if Windoze bloatware is not bad enough, future updates are severely restricting customisation.
The reason that I opted for Windows 10 professional (rather than the Home edition) was the ability to suppress some of the worst features of Windoze. Looking forward to October / November when I plan to migrate to Linux!
Which flavour do you fancy? Ubuntu perhaps?
I’ll probably go with Ubunta v18.04.4 LTS as you’ve said that its works well with the HP Laserjet MFP M28fdw.
Plan is to install it on an old Win7 laptop, verify that the printer works OK, try and connect my 2 iiyama monitors, and if OK, install on my current Windoze 10 laptop.
This is how my Raspberry Pi connects to the NAS share:
sudo mount -t nfs 192.168.1.8:/volume1/Nextcloud1/ /media/NASshare -o mountproto=tcp,vers=3
(It’s all on one line)
@Krister_Rosendahl Which NAS do you have?
I’ll try those additional options later…
It’s an Asustor AS3202
Well, it thought about it for about 20 seconds then returned:
mount.nfs: access denied by server while mounting 192.168.1.117:volume1/GnV_Common
So, I will stick with SAMBA - as it works as we want it to.
On the Asustor I had to separately enable the NFS service.
Here’s a link to some troubleshooting tips:

same too on the Synology NAS which have implemented and I think I’ve tried most of the solutions in your link but will review them.
Here’s an interesting thing which I just discovered (haven’t tried it yet)
Windows 10 sans the spyware & bloatware
Has anybody using Ubuntu upgraded to LTS 20.04.1 yet? Any issues?
Nope Geof - sticking with 18.04 LTS for now. The first point release of 20.04 LTS has been released but there are still a number of people reporting issues on Ask Ubuntu and I guess I will keep with what I have got for now (18.04.5 currently - updates to April 2023) until things stabilise. I did the same with the move from 16.04 LTS. To be fair, looking at the issues, it very much seems to be connected with dual booting with Windoze and various «wizzy» add ons - I personally prefer a vanilla installation - horses for courses.
Good advice Graham - I generally wait a bit too - aware that I’m less expert than most linux users so need others to sort out the bugs first!
I’m more a Fedora guy - keeps you on you toes 
If you have Linux and want to help the fight against Covid-19 then this might be of interest…
My first linux distro was Red Hat - and using KDE - it was love at first byte - but it’s been Ubuntu making life easy for maybe a decade now.
Mine was Slackware, for a work project having persuaded management that development for a HP-UX system would go faster if we had better machines.
The answer was “no” - they were not going to buy hardware that they couldn’t reuse on another project so they weren’t gong to buy more HP workstations, or any i386 Unix licences of any flavour. I think they were a bit surprised by my response “OK, buy us some decent PC’s and I’ll put Linux on them for free” - about 1995 as I recall.
