On cars there are diminishing returns on fuel cost and repairs. You end up paying more keeping something which is why I got rid of that fucking awful Fiat and will be getting rid of my Citroen soon.

Edit: rise in fuel prices = inefficiency liability.

This might make you rethink that strategy

LOL no. 19-23 mpg. In no way that makes sense. Even in America.

No, I wouldn't either, but the points he raises are what I was hinting at. If you have a car that is running well, reasonably cost-effective to run and has no major body / rust / mechanical issues, then why the hell risk junking that for something like he says that is really designed with the good for 70,000 miles ethos and then scrap it for another plastic car etc, which is not good for the planet either.

That doesn't make economical sense here due to the petrol prices.

Say 2014 C3 ...  100k miles lifespan for a car at 66mpg, that's 1515 gallons. 4.55 litres to the gallon = 6893 litres ... £1.92 / litre. £13,236 for fuel

Say Vince's Safrane ... 100k miles lifespan at 34mpg, that's 2941 gallons. 4.55 litres to the gallon = 13,382 litres ... £1.92 / litre. £25,694 for fuel

If you sell the Safrane and buy a C3 with 25k miles on the clock it'll cost you £6000. In 100k miles you will be better off by £6,694.

The safrane is worth £0 when you sell it. The C3 £1200 at 100k.

Put the £6694 in the bank, buy a nice smartphone with the difference and then get a newer C3 in 3-5 years. Total cost of ownership is MUCH lower with efficient engines.

The scary thing is if I sell my C3 now it's worth £1000 more than I paid for it because the rising fuel prices are compressing the market into efficient cars.

Your funeral  :-//

I ran shitboxes for years - one broke down on the way to a job interview. I didn't get the job.

Yes, CRTs are definitely interchangeable.

So monitor hack, shouldn't be overly difficult.

Old Hitachi/Matsushita schematics is too old and something seems to be missing but those two neck boards are very same.
Older neck board uses 74S03 as parallel inverters powering contrast trimmer directly and newer one seems to be different only from there.
Oldest has no neck board but contrast pot connection is pretty exactly same as 74S03 version of neck board.

Are all those 54620-series machines already closed.
More revealing solder side picture of neck board would be nice.

Completely forgot 54645A/D, its resolution was clear.
313 V x 512 H (pixels)

That's clearly PAL, but proportional and lowres.
Is there visible space between H-lines?
Back in the day CGA was clearly using only every other line of available physical pixels.
From pictures online there could be something missing but it is not much, dimming can reveal something but it doesn't change anything.
Full hires for PAL is 31250Hz H-sync, 31500Hz for NTSC.
Old Hitachi/Matsushita schematics has 24270Hz as H-sync and 60Hz as V-sync so 404 lines possible.

PAL and NTSC were also defined as 720 pixels wide, but no idea how much was physically available, not much more I guess.
One thing I remember though, very small pictures were exceptionally sharp.
So more than 500 was a norm already back then but no idea what was the major barrier, screen material or cathode ray energy.
FET in newer neck board indicates that rising time had a role.

From online pictures I'd say that 54600B grid is 100x60 pixels, vertical center line is around 128.
Vertical 256 must be a grid area, horizontal 500 seems to be all.
54622D pictures were pretty bad but horizontal pixel count seems to be more than those 54600Bs.

How this all then should be converted to VGA or SVGA.
Anti-aliasing is difficult when contrast is high and lines narrow.

One other thing, PAL pixel is not round, for that it needs a 5:4 screen, but that is for 576 visible scanlines.
Very nice, and clear.
What is the shape of the screen here?
Online pictures are pretty hopeless.

PAL and NTSC don't have pixels, only lines. Horizontal resolution is only limited by bandwidth.

What is your point?

You can't discuss PAL or NTSC in terms of pixels, they are analog standards not digital. I know where you are coming from, there ARE difgital standards that are basically equivilent to PAL and NTSC and can be displayed on analog monitors but they are not PAL or NTSC (ignoring the fact that PAL ant NTSC are in fact colour / color encoding standards)

It's fucking shit so YMMV anyway. One of our outsourcers uses it.

As for it not being compatible with your phone, are you running some 5+ year old Android crate? That's usually the cause  :popcorn:

As for interviews, they are all Teams or Zoom these days. You have to suck it up if you want the money.

We usually want to meet people in the office. They'll be in the office at least 51% of their working time, on average (that's the rule), so if they're not comfortable with that, well, their problem.  We also insist on a bunch of other things, like proof of citizenship and so on. Many rôles require that the applicant is a Swedish citizen.

And Zoom is officially forbidden in our environment. 

Teams works on Linux. It's a hog, a fucking hog, but it works. To do a job interview, you'll need a camera and a microphone of course.  I have a colleague who likes pain, so he runs the semiofficial Linux distro we have built in-house. I run on OS X. Company Windows of course is so amputated it is completely impossible to use.
