I meant, of course, that the Pi400 makes no sense.

The pi400 doesn't make any sense in the rough and tumble of the shop, but 
the pi4 works great.

That makes two of us, until this wuhan flu shit hit, I had visions of 
starting a new carear, tuning towers for AM broadcasters. Its damned 
near a lost art today as all the old BC engineers that knew how, have 
all died of old age or stuff that goes with it, and many stations have 
modified their towers without retuning either because they couldn't 
afford it, or couldn't find anybody who knew how, leading to lots of 
bitchy and expensive tramsmitter failures they don't need, caused by the 
VSWR.  I've bought some gear that will draw me a new smith chart in 2 or 
3 minutes, but using it puts me in a doghouse at the bottom of the 
tower. And good weather, no static charge in the air. And that will mean 
travel all over the country, a heck of a lot more real estate than your 
home Isles.  And at 86, I'm not in that great a condition myself. I can 
do it today, but for how long?

So take care and stay well Andy.

Cheers, Gene Heskett

Hmm, last night I installed the Linuxcnc dev environment on my Chromebook
now it supports Linux in a container using Debinan Buster. Seems to run
perfect but don't ask about the latency!
So no TV required if I ever get to travel again! Hang on, maybe I can cast
the screen!

No, the Pi4 makes no sense as a machine controller. I got it to be a LinuxCNC 
dev environment that I can toss in my suitcase when I travel and plug in to the 
hotel TV

If I ever travel again.

But that isn't possible if the pi is a pi400 I assume?  Too much plastic 
in the way. :(  That, and a $4 chomerics style keyboard scares me. The 
pi400 may fill a market niche, but I don't think we are "that" market.

It need not be longer than 1.5 inches or so since the RPI mounts on top of (and 
get power from) the 7C80/7C81 via a 40 pin flat cable

Zero (units)

The Pi plugs straight in to the board.
