JAMMA Extension Cable - Interest Check

Pcbs arrived, parts still in transit cables yet to be ordered. The blue looks spot on 20% bevelled finger, the connector end I thought was a manufacturer issue but alas when i checked my order I forgot to tick blue solder mask leaving it green. So that's just that for now.

One finished in 50cm, I sort of wish some sellers could measure better, they are both 50cm cables but the atx is about 3cm longer than the idc.

I keyed the jamma plug because I typically use the wire colours to identify direction when i am digging around in the back of a cab and they are not on this cable.
 
I still have a few boards left. So in an effort to clean up my work bench, I am happy to ship my JAMMA extender anywhere outside of the US that @raynex does not cover (as long as you are happy to cover shipping).
I have both 30cm and 50cm cables, which results in a total extender length of just under 40cm or 60cm when you include the PCBs. l can also do custom lengths but this is limited to 6 extenders because i dont want to have any cables left over.
I ordered 50 of each PCB as the cost after special deals was almost the same as 20 of each but once these are gone I am not sure if I'll do more. While I did a few without a voltmeter, I really liked this function and ended up soldering a voltmeter into all of my remaining cables. It would be interesting to hear opinions on the value of a voltmeter that measures at the JAMMA edge as I have found it useful but can see issues relying only on this reading for more complex applications. Photos below of a play test of one in my MVS cab.
I have been thinking of doing a JAMMA harness in a similar fashion, with a board at the JAMMA edge and one at the coin door. If I did this I would make sue that it carried kick harness and multi LCD screen signals, that it had a built in test and service button, that it accepted multiple coin mechanism plugs as well as having an easy way to wire buttons and joysticks with short cable runs. I was planning on doing this for my cabs but it would be an expensive harness comparatively. I would be interested in hearing opinions on the idea.

Posted an update to the OP. A couple more and I'll begin the next batch.
 
If you're still taking interest for the next batch I'd be in for 1. Thanks!
 
Just posted an update on the next batch in the OP. Hoping to have everything in November and begin (maybe even finish) making them in November. If you're interested, please reply to this thread and I'll add you to the list.
