At least in the case of my car (1998 VW Passat) the "gadgetry" firmware source code can be requested under the Open Source declaration found when you dig down through the infotainment panel menus and

You could try Octave, or Scilab. Both are free, and very comprehensive Matlab clones. They are 'extensible' and you can link in compiled Fortran libraries. The thing that they are not is an

I'm pretty sure Mathcad 7.0 Professional... although it's old... is still under copyright protection. Just the same, that sight forces you to 'register'... and login... before you can even verify,

That's right. As a result, Keysight never stocked spare parts for the third part PSU. Broken PSUs were meant to be sent back to the vendor for repair or scrapped. In addition, while someone at

Peter I applaud your warranTy shirt.?Some 20+ years ago before I retired, I also had a problem with a company when I asked for schematics for a piece of out of warrantee T&M equipment that was

Here in the UK, Keysight offer a repair service, but if the equipment is maybe 15 years old or more, they often return the equipment unrepaired and declare it beyond economic repair or declare that

Yes I should have clarified.? The term IP usually insinuates a trade secret or not to be shared so I only meant to say they should be shared with the customer if they purchased their product.? I

I love this story Pete!? This is very often what I deal with at my work.? Manufacturers charging thousands of dollars to repair their own equipment and I end up repairing it for a few bucks in

Generally yes, but it looks like his case is just starting. It could well be something different, but I doubt it. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Schematics and service manuals are most certainly intellectual property.? What makes sense is that by purchasing or owning the equipment you are granted some rights to this IP in order to maintain

Just this very day I received some schematics and manuals for some early Canberra nuclear equipment. That is good "customer service" for someone who isn't even a customer. But you can bet that I

Wouldn't cataracts be easily discernable with the unit off?? You'd be able to see areas of the adhesive bubbling that correlate with those areas OP pictured?

Yet, I have called many companies and they were happy to send me schematics of older equipment.? Depends on whether the engineers or suits now run the company.

A company I worked for had an older model EIS (electrochemical impedance spectrometer, basically a low frequency higher power VNA), a very costly piece of equipment.? It failed one day and they

Could be; my dad is 82 for a few more weeks.? ?He's still sharp and active.? Mom's 84 and suffering from Alzheimer's, unfortunately.? ?So far it seems to just be a loss of short-term memory.?

Maybe it's the programming and writing which keep his mind sharp.

Vladan, You did explain your positions clearly and explained very well why HP and other manufacturers have moved away from providing schematics.? That was never my point.? My point is that it is a

Frank, yes I see that you are very passionate about this. I tried to present the manufacturer's reality, the drastically changed market conditions since 1985, the increased complexity of current T&M

Thanks Dave, I shall research. I might be skilled at it as I have a few to do. Dave M

This looks like what has become known as "cataracts". The PVA glue used to adhere the implosion shield to the CRT glass has deteriorated. It can be fixed, but it's not easy and it's a bit
