Where can I buy a large analogue meter?

The company I worked for prior to my recent retirement made a wire-wrapped supercomputer in the 1980s. We sold one into China, and they took it apart and copied it. We started getting support requests for computers we'd never manufactured.

Which is why they went wrong so often. Yeah lets just hope two things touching with no solder or pressure just happen to conduct. It's the way kids make stuff. Twist the wires together and hope for the best.

Charge them for it and make money.

I'm guessing this "supercomputer" was about 1 MIP. My computers collectively do 30,000,000 MIPS, in my garage.

Oh I dunno, I did wirewrap a complete 19 inch rack with eurocards long ago, Had some RF too, well hundreds of kHz ..

This was also fun:

or this from long ago:

That's what I have mostly done. It's not extremely busy but I like to snoop on what's coming and going from the local airport. There is no ship traffic in this state :) With global warming maybe we will have an ocean in a couple of centuries.

I've picked up a little SSB traffic but this area requires good antennas to pick up anything besides 2m.

I've still got the tools and an assortment of wirewrap sockets but haven't done a project in a long time. I got away from hardware when surface mount came in. Even with magnifiers I don't have the vision to deal with that anymore.

You assume there is a circuit board to solder anything to. Wirewrap is great for prototyping before you bother with a board. Of course there's the dead bug method.

Then there was the hybrid where circuit boards slotted into sockets but there was no backplane so you wired it up point to point.

Those all look soldered. And that's the way I like to do stuff.

I astonished someone at work when he was trying to read a surface mount resistor value through a magnifying glass. I glanced at it without one and told him the value. Apparently I have the eyesight and the hearing of a 16 year old. Unfortunately not the body.

That's not a general problem. There was a period with the early Athlons that didn't implement some of the new Intel instructions but I've leaned towards AMD with no problem.

It wasn't AMD but I recall one processor that ran CP/M and DOS, both rather poorly. National maybe?

I still see solder. I've made stuff without a board, but I always use solder or things fall off.

It's a f****ng problem here. I run the Boinc projects Cosmology and LHC that use Oracle Virtualbox to run Linux under Windows. It slows the interface to a crawl. The same doesn't happen with Intel.

I use .ts format as it is more flexible and easier to fast-forward and go back in. bp1.ts is just airtraffic, weather air pressure etc from server on an other raspi. other audio goes to the audio directory.

Nope, vast numbers of DEC minis were done that way.

The coal trains aren't popular. There still are some surface level crossings where you can wait forever for the train to pass.

Just about...

This one is paved in the downtown area but east of town it's gravel but fairly smooth.

Amtrak has been on life support for a long time. I briefly worked for Penn Central when they were going under. You had to have money in your account before the bank would cash your paycheck. Amtrak took them over with all the problems. The tracks were a mess as was the rolling stock. There were a number of the '50s streamliner engines that were scrapped because nobody wanted to work on them.

Amtrak did eventually get the tracks back in shape but only on the eastern corridor.

The US would rather cut its nose off to spite its face.

Nonsense.

Actually, virtualization capabilities were pioneered on the Opteron processors with SVM (Secure Virtual Machine) circa 2004. It was several years later before intel introduced the equivalent VT-X support (right after Intel adopted AMD's 64-bit extensions). First generation SVM still relied on paravirtualized memory management, but the second generation added nested page table support. Intel copied that as well with EPT.

VT-D is a completely separate thing (I/O virtualization rather than CPU virtualization), and it relies on specialized PCI hardware that can be configured to provide multiple virtual devices (Virtual Functions in the nomenclature). Not something you'll find on a desktop box generally (although NVME cards and many network cards support SR-IOV).

At SGI we helped pioneer hypervisor development with a project called Crucible - we ran Windows and Linux on a two-processor HP Kayak simultaneously, in 1998.

I've used rufus to create bootable USB sticks for Linux distros. Same rufus?

It's not great. They've been improving it supposedly.

Surface mount is easy on those boards with the round isles. I have reading glasses from the local drugstore and for the small SMDs I put 2 reading glasses on top of each other. Strength adds up. You do need to be a bit closer to what you are doing then. So far no problems. Have a small fan blow the smoke away from you..
