Where can I buy a large analogue meter?

PDP15 backplanes were wire wrapped for a good reason. (square meters). wire wrap is about ten times more reliable then solder joints, and can more easily be corrected.

They didn't try very hard to make it even remotely worth having as a home computer. Plenty of much nicer and cheaper ones with much better graphics. Most makers understood the importance of that aspect.

PS2 was a blatant attempt at a FUD lockin and had the interesting effect of uniting all the other PC clone makers to generate a better ISA bus.

It really upset the scientific instrument makers who had their own series of dedicated daughter boards that plugged into IBM PCs. It even caused Intel to go on make an OEM 386 PC clone of its own for industrial and scientific users which ISTR still had some old style slots.

Mainly because no one was every fired for buying IBM.

6502 punched well above its weight for the time.

And interestingly whilst selling an IBM AT to Russia was entirely legal at the time they came out selling a faster 8MHz Compaq clone was not! Amazing what having an inside track on the political system can do...

That is a separate issue to the silly claim that IBM didn't believe in the PC market.

Unsurprising that IBM couldn't compete on price. They couldn't with the original PC or AT either.

But because it was later, it was better than the Vic20 and C64 which both sold very well.

That's overstated on the uniting. DEC didn't go that route and did its own stupidities.

Yep.

Yes, and preceeded the IBM PC,

Not convinced that that was the reason for that.

Possibly apocryphal but the rumor was Christensen tried to get his bosses at IBM interested in PCs. A memo came down the chain of command saying if he wanted to play around with them on his own time that was okay but there was no future.

That was IBM's idea of a small computer in 1980. Despite the 51xx naming convention it had nothing to do with the 5150. The 5100 was a 'portable computer', meaning it didn't need a forklift but it weighed about 50 pounds.

The 5120 was a strange beast since it retained the 5100's APL capability with APL hieroglyphics on the keys, but also had BASIC. The idea was the

5120 was a starter set and you would eventually move to a System/34 which also had a BASIC interpreter along with RPG II. The 5120 had BRADS, sort of a low rent RPG. It also has an assembler of sorts and a way to get into a system monitor. That provided me with amusement when I got tired of the inventory control system I was supposed to be developing.

A year later the System/23 came out. It looked a lot like the 5120 but used an 8085 rather than the PALM 'microprocessor'. The PALM was actually a bunch of gate arrays running microcode. (Put All Logic in Microcode) which was how they emulated the System/360 to port APL.

All this obscure history had its impact on the 5150. Boca Raton wasn't completely in a bubble. System/34 BASIC went back to '77 and the System/23 design using a 8085 may have stacked the deck for Intel.

I'll admit that at the time, while I made my living with computers, when Joe Sixpack would ask me what they should buy and what they could do with it my answer was basically 'beats the s*it out of me.'

And after that, IBM woke up and smelt the coffee and changed its mind on that.

I wasn't really talking about icons. Just a GUI so you can use a menu, full of English words.

I do prefer English on a washing machine, because whatever moron decided a tumble dryer is a square and an iron is a triangle needs his head read.

Question mark in a circle.

Not sure what you're getting at. Windows makes it easy to find what you need.

I hope the USA dies soon. The whole world hates them. Maybe have a word with Putin?

ROTFPMSL!

That's the most f***ed up site ever. What's the difference between: Other race Unknown race Not Hispanic or Latino Unknown

Glad to hear it.

You f****ng idiot. What makes you think Bowman is in the electronics group? Learn to use a computer there's a dear.

I'd assume other race includes Asians but the number seems low. No idea on the two unknowns. The UCR (uniform crime reporting) system is anything but uniform.

Then we get to Hispanic/Latino... Many forms have the category 'White non-Hispanic'. I check that one. Hispanics sometimes are white, sometimes not depending on which is more advantageous. Some are actually old stock Spanish. Others are mestizos or some other complicated mixture of white, black, Asian, indigenous, or Klingon.

It's like our stellar VP who prefers to identify as black rather than Indian.

"A study from 2014 estimated the genetic admixture of the population of Cuba to be 72% European, 20% African and 8% Native American"

That's Cuba but may typify most of Latin America.

But we all know there is no such thing as race; it's just a social construct except when it isn't.

I think the research dates back to 2017 but it finally hit the MSM. It seems dingoes aren't quite dogs. They look like dogs, interbreed with dogs, but aren't quite the same.

I like dogs but don't care for blue heelers (Australian Cattle Dog). Metaphorically speaking I think they were God's first attempt at making a dog. When he saw the outcome he said "Oh s*it, I can do better than that and tried again but failed to discard the first version. Since they were a cross between dogs and dingoes apparently my gut instinct that they aren't quite a dog was correct.

Of course, this has nothing to do with humans.

Actually I read alt.home.repair but given the amount of cross-poasters it's hard to tell. I think I did subscribe to s.e.d at one point but found it as on point as a.h.r.

That's because I'm in it.

Which are sterile. If your theory is correct it doesn't work that way for humans. If anything fertility is enhanced.

A little more. The rule of thumb is 20% of body weight for a dead load,

25% for a live load. The theory is a rider works with the mule where the panniers require more work to balance.

It was for horses but I saw one site that claimed the rule in the UK was

10%. Either the UK breeds a lot of draft animals or not too many people ride. Morgans are a popular breed in the US and go about 1000 pounds. By that rule, anybody over 100 pound would be sol.

They no longer breed their own mules but the Ninemile Remount Depot favored Morgan mares. Morgan horses themselves made good trail horses so they would bring good traits to the mule.

Most of the pack stock in the region is trucked back to Ninemile for the winter. I can tell you that you get a lot of new friends when you show up with a pickup full of hay on a cold winter day.

Not many people ride horses here, but I knew someone who had some very powerful (shire?) horses. But he pulled things with them rather than carried.

Doesn't the USA use gasoline for everything now?

Draught horses need a lot of oats so they're usually gainfully employed rather than hanging around waiting for someone to ride them. The breeds are interesting with roots in medieval times when you needed a big horse to carry Sir Lancelot and all his armor.

Mostly but some still use horses. They're handy for small woodlots where it's hard to get a tractor in. Despite 'Yellowstone' you're more likely to see a cowboy on an ATV than a horse.

They're used for packing into the back country and pleasure riding. I was out in the woods yesterday and saw a group of 4 people on horseback.

The fairs in the northeast have horse and ox pulling events that are popular. Horses are drama queens. They prance around and are hard to hitch to the stone boat. Then they poll in fits and starts. The oxen come out, are hitched, and walk off pulling the weight. When they stop they're done.

They used to use them in schools .. plugging in shunts or multipliers as needed.

You could easily knock one up ... wind a coil, hardboard pointer.

Yip, two foot tall. Surprised there's no market for them now. They do still teach kids what electricity is, right?

This one is a terrible actor, and so is the horse:

That's a good question seeing some of the students we have I'm not sure they do. Or those we have didn't understand but just memorised paragraphs from physics book.

He has had better vehicles... I'm not big on fabricated accents in historical dramas. 'The Vikings' come to mind where each actor invents their own version of mangled English. They should be speaking Icelandic which is the closest extant language to Old Norse.
