@richard.faulkner Had a quick trawl in the garage & found the packaging for it (but not the item itself)...

It's from Best Electronics & is labelled as "ST/MEGA 40 PIN CARTRIDGE PORT EXTENSION CABLE PRINTED CIRCUIT BOARD SET" - it comprises a small PCB to plug into the cartridge port & a heard & the other board was the PCB with the equivalent cartridge port on the ST.

If I get chance to dig a bit deeper for the actual boards I will & will post some more info.

Of course, it's entirely possible that they may still have some stock of these...if you can get an answer from Brad - I'm pretty sure I got it from him at one of the shows around 20 years ago

Brilliant info. Thanks so much for looking!

No problem - we all try to help others where we can...some of the others are far more experienced with the actual mods/repairs etc. so the rest of us help as/when we can :D

Fully assembled Cartright II ST/Falcon Cartridge port extension cable set. CB102118 $39.95

is listed. Which is about 22 quid. I Wonder how much customs plus post office rip off charges i'd end up paying...

Probably not cheap...I just got it in kit form (just the two PCBs I think) but that may no longer be available.

There isn't a part number per se on the packaging either...

If I can find it, I can put up some measurements (and maybe someone can do a schematic & layout for a modern equivalent?)

That would be great - i suppose the difficult bit is making the cartridge (male?) side and the socket you can buy somewhere (Although i've read they're expensive i wouldnt mind paying for reliability - i'm making music and computer says no eats up precious time! ) :)

The male part should be easy. You could get any PCB fab to make one. The female part, on the other hand, is as rare as unicorn snot. You basically have to pull one off an ST donor board.

For anyone interested (as google shows this thread when searching for Cartright), I ordered it from BEST (I couldn't come up with anything better to make my order >= $50 USD). It is a nice gadget and most importantly, it contains the original cartridge female slot which is basically impossible to purchase anywhere else.
Oh and customs costed me nothing here in Australia. On the other hand, postage fees were $50 USD, yes, the same amount I paid for the goods. Oh well.

There was a buffer one back in these days published in the computer magazine c't ...

That's worked really well! I never had a problem once i went to the mega st so i forgot this post even existed :)
