I find the simple abbreviation Twit similarly viscerally satisfying.  ;)

If we keep on this current tack there is a good chance that we will be heavily monitored and that will effect almost everyone here negatively as we would not be able to deviate of the core topic and that truly would be a backward step.

So please, make it up and lets move forwards.  :horse:

Reminds me of this thread at times ...

Yes we've been drowning in mud mostly today. In a moment of delirium caused by an hour of JIRA ticket shuffling earlier I decided I'm not talking about anything other than TE on here any more. Cars, computers, politics, crazy people, dick swinging, petty arguments can fuck off. They detract from the good things in life like scopes, signal sources and that bacon smell when you solder your fingers to something.


And on that note, still arguing with test-equip over this ROM. I have decided that life is too short for this crap, have opened a claim and am working out how to burn 74S267's at the moment and will load the damn code in myself.

To do this I figure the best approach is to read the existing ROM out first and validating that I've got as much as I can out of it. I'm down one address pin but I worked out that if I read it and assume that's 0 then I can at least validate half my burned ROM's address space is fine. I am now attempting to do the following:

1. Order some bits. Have a medium shopping list.
2. Use a cheap arse arduino clone to read the ROM out into PC and diff it with the one I have to validate I reverse engineered it properly.
3. Add some switching magic for the burn voltages and an external power supply to burn the new ROM. Check it carefully with a scope.
4. Burn new ROM and validate.

Fucking amen. Something I've tried to encourage but then I get dog piled for trying to direct the thread to my own selfish needs which is completely untrue.

And since I have no time today to work on the 465B re-cap this mostly likely will be my one and only post.

Finally......you notice then whenever this thread goes off the rails it's always the same common denominator?

If that doesn't work, you can always just glue some gears on it and call it SteamPunk; it's already got that industrial-revolution-era patina.  :-DD

Hey Pat, you should check if you still have the handwritten receipt for that lampholder and lamp and check the signature on on. If the signature reads Thomas Alva Edison you'd make a mint from it at auction.  :-DD

A three phase supply........

--- End quote ---

Even in Italy I have 3PH 380VAC... Germany did a wonderful job in wiring up their grid. The three phases there are almost everywhere.
I would like to buy it a play with a 220VAC to 3phases 380VAC VFD... if I would be in UK.
Not trying to push it, I am so surprised it is still dancing for sale and nobody has bought it already.

--- End quote ---

The three phase is what kills interest in it. You just won't see a three phase installation anywhere in the UK where the demand is for less than ~125A single phase. It's just how the power company has always done it. Three phase installations outside of industry or large buildings are very rarely seen. It costs a small fortune to get a three phase supply installed anywhere that wasn't planned with a 3 phase supply ab initio. It almost always entails significant streetworks (of the digging variety) which puts a several thousand pound price tag on even the most trivial work.
