50way Edge Connectors
« on: 16:46, 31 March 13 »
Where do people generally get their expansion port edge connectors from? They seem to be silly money! £17 odd for a single IDC edge connector!

It's not a good price at all.
You are searching for a clipsable ribbon cable version or for a pcb soldering version?

Preference would be for a ribbon cable version. I already have some short 50 way ribbon cables from Arcade PCBs that I could cut one end off and use. That would give me the greatest flexibility with experimenting as I would then be able to use jumper wires to breadboards, etc.

Hi Martin, just solder a dual row 25pin idc male header as used on pcbs, onto the existing edge connector.
You can then use cheapo 50 way idc connectors ie scsi type and the connection is far more reliable.

 :o  is that really an acceptable thing to do??
 
I like the thinking, yes, but when people solder wires directly to arcade PCBs because they haven't got the right connector, it always make me want to chop their fingers off to stop them ever going near a soldering iron again  ;D
 
It would be an awful lot easier and cheaper mind.

No, never solder directly to a PCB with wires !

The good connector can be found on a USA online shop for $0.50, but they don't want to ship outside the country.
On ebay, you can easily found the soldering version for PCB at a good price...

Were wires necessarily suggested? I’m not experienced with soldering, but perhaps the suggestion was to solder the 50-pin IDC directly onto the contacts of the edge connector… if that’s even possible. :P Wires would be far too messy, in any case.
[The owner of one of the few existing cartridges of Chase HQ 2] mentioned to me that unless someone could find a way to guarantee the code wouldn't be duplicated to anyone else, he wouldn't be interested.
Did he also say things like "My treasureeeeee" and is he a little grey guy?

Eliot still has one 50pin edge connector for 2.60 EUR in stock. Have a look at his webshop for more information.

Thank you - that's a source I wasn't aware of. I'd rather do it properly so I've sent Eliot a mail with my details.

That's right the edge connector sandwiches very nicely between the row of pins and tidy spot soldering produces a very nice neat, stable and strong connector...i have my 6128 configured this way for the expansion port and printer port.
I believe Bryce also has his configured this way but cant be certain.

If it's done carefully the end result looks pretty good...

And, it has to be said, can be cleaned up pretty well with solder wick if you wanted to remove it to. If I end up not being able to get an edge connector for a reasonable price then I will do that, but I'll see if CPCParts does indeed have one left first.

Hi Martin.


You can find them at Reichelt. Not sure about extra postage:
STECKER 50-254 - SLot-Stecker, RM 2,54, 2x25-polig bei reichelt elektronik


I was posting some photos about the soldering alternative here:

It's not very messy at all ;-)

The Reichelt part is for soldering to a PCB, not IDC. The cable (IDC) version can be very difficult to find now. I used up most of Eliots supply for the MegaFlashes. But at least they all went to CPC users and will hopefully all be used. I regularly search for new supplies, but they are either too expensive or too far away.
