so... i have made a few RGB scart cables,, but my issue is my soldering of the din & scart plugs is not the best.. i tend to make a blanking signal from 5 volt via a 270ohm resistor to lower the voltage.
as i found that using the sync as blanking would cause occasion jumping of the screen, and fitting a capacitor on the blanking line would cause ghosting..
anyway so i thought i would get some commercially made scart leads (cheap as chips) and some 6 pin din leads and make a small connecting box... problem is : 6 pin leads are not that common and expensive so i thought i could use 5 pin ones (as i will not be using the middle pin which is lum) initially this seemed like a great idea,, then i realized there are two types of 5 pin pin din the ones with the same pattern as the 6 pin (240 degree) seem just as rare ,, the other type are 180 degree (often called MIDI cables, these are very cheap) so i thought what if i brought some pcb din sockets and replaced the stock ones on the motherboards then i could use the cheap cables. but i dont think the solder points would line up very well ... has anybody else tried anything like this or tried a different solution
i have a few 464's to make cables for so just trying to get the best / cheapest method [size=78%] [/size]
Just for the record, there are actually THREE different types of round five pin DIN plugs/sockets. The third type is the domino type (so called because the pins layout looks like the five side of a dice).
And yes, the PCB pad layouts for DIN sockets does not appear to be a standard between different manufacturers even for connectors with the same number of pins.
Also desoldering PCB mounted DIN sockets from plated-through PCBs is not that easy.

yeh,, guess i will have to practice my soldering some more ,,, biggest problem is my rubbish equipment. Or maybe it is just me ! lol
the newer cpc boards seem much more fragile than the original giant ones..
Honestly, I think I didn't understand the problem.
So you have issues with soldering cables because of bad equipment - and now you plan to replace the sockets on the mainboard in order to use standard Midi cables?
Just for the record, here's all the different types. I definitely wouldn't start swapping sockets on the CPC PCB. You might find the right footprint, but your CPC is then compatible with just one cable and incompatible with all original or modern expansions that stuck to the original pinout.

cheers guys,,, yeh i will stick with the status quo... i have ordered some new scart plugs from a better supplier than my previous ebay jobs maybe they will be a bit better..
ETO it's not that i can't solder its more i was looking into ways of having a molded connector rather than home made ones as they will always be more prone to failure
i may look at better quality din plugs as well ..
got some cables to make now in my soldering room aka my kitchen ! lol
I'm just surprised at the lack of 6 pin din leads that are available
Why are you suprised? 6 pin DIN cables weren't ever commonly used for any computer connections other than Midi.

i thought the same type of 6 pin where where used in other applications such as guitar / amp leads etc.. also i think some PSU for external hard drives and routers etc used them, specie uses them for power as well on the later +2A,+3
Well, the original DIN descriptions are helpful. Maybe they aren't fully translated into other languages. I don't know. But the problem is the same as too often. Companies aren't interested in making things easy for the customer, they love to have their own solutions. So they can sell adaptors and stuff.
I can only hope that in CPC world we stick to quasi standards. Until now we do good (not very good, not excellent, but good). :) :) :)

Even if they did use the same connector, they would need to use the same pin connections, wire type etc. The Spectrum uses a 6 pin DIN connection, but it's attached to the PSU, so it's not a stand-alone cable.
