Fantastic, i'll look forward to see a video of it when it's all up and running. ☺️

basically if you don't have the gear then don't attempt it. low heat so as not to lift the tracks, never apply heat for more than a few seconds even with a proper temperature controlled soldering iron, and NEVER EVER EVER attempt to prise the socket out with a screwdriver! if it doesn't come out with finger pressure then its not completely DE soldered. there is no shortcut, anything that goes wrong like pulling away tracks, or pulling out the through hole insides WILL result in tones more hours in corrective action which takes skill to do. here is a video I did 9 years ago with the tools you are suggesting to do it.

not tried that yet but I will have a quick go ASAP.

I could have sworn that I fixed a board where someone had plugged the power into the wrong socket(the person even said he had). come to think of it, it may have been the switch input as the resistors had fried and even scorched the pcb(it was about 15 years ago). my bad on the power and triac plug.

Good stuff, thanks for sharing Bob. Likewise Im happy to get involved in a group buy if anything comes up. @Road Runnerdoes the extraction tool work on both pins and sockets? If so then it would be worth investing in.

When I saw the price for the extraction tool it made my eyes water! Just to be pedantic the two white connectors are 15 and 12 way (PSU) so no possibility of mixing them up. Have to agree though that they chose the wrong type for the PSU connector but then again they didn't expect them to last 40 years plus!! Mind you I have seen many examples of PSU connectors looking almost new so old loose female crimps are also to blame. Never heard of Gowerpoint before but there is an example on here showing the connectors but unfortunately no documentation as is often the case.

Nice find. i have the extraction tool for these it not cheap for what it consists of but it’s probably worth the investment as it makes repinning a lot easier. It was a good idea from Barcrest TBF because with the plugs being colour coded it help to prevent wrong connections from engineers that were probably just getting to grips with the new MPU based machines(with the exception of the power and triac that used the same plug and colour on the MPU3 range). They probably should probably have used totally different type for the power plug as overheating was a problem. im sure Gowerpoint used this type of connector at some point. pity they are out of print but if a group buy is on count me in.

Well the saga continues. It's now the 11th year I've been looking and this time I've come up with another AMP document. Of interest in this one is the addition of two more pin types which have soldered tabs for PCB fitting. Not seen these before but they are the normal type of pins (ie the crimp ones). Still no further with the solid pins though and whether they are a separate item or come pre-fitted with the shells. Comboline.pdf

Spot on, looking forward to seeing the finished article! 👌

I put some in my basket to see, they reckon that they will have more in stock soon. The lad in Austria is happy to have them delivered to him, he can then bring him back over in his luggage. I'll also get him to ask if they have, or can get, any suitable pins/receptacles for these. If they get more in then we can all order up what we need (within reason).
