The other piece of you puzzle can be found in the aurora manual - as it gives the key tails positions to IPC pin row and colum definitions

that should assist

Given he lives in the outlying regions, it's not suprising it takes a while - but I have to say I have several products from Tetroid - and all have been packed really well, documentation included to get you going, and the boards themselves are excellent build quality.

Top Marks!

A lot depends on the type of socket used - push instert / push eject are the best, as it's a positive action for both operations, and I believe the socket has a switch to give 'card present' when inserted. Even someone with stubby fingers like me can get a microSD out of one of those sockets. There ...

It looks like a 4 layer board - so that probably won't get you very far.

I'd second what Tobias says, a new keyboard. Repairs? - even a small amount of silver conductive paint doesn't hold up for long. I just replaced one keyboard where it had failed on the bend where the keyboard tail tucks behind the metal backing plate - this is such a tight turn - the plastic had gon...

I have a spare 8049 as I recently put a Hermes chip in one of the QL's i have, so you are welcome to that if you want it. Just PM me. But I suspect the issue is more likely the keyboard matrix...

Those old intel Microconrtoller chips are quite robust - a touch screen company i worked for years ago used them on one or two of their controllers (well the ROMLESS version), and they are very tolerant of abuse. Simple resistor diode protection on the inputs was all we used. The QL has resistors on...

a fracture in the keyboard tails is one of the most common 'failures - particularly if you've had the lid off a few times, - it's also possible that the sprung contcts have moved too far back in those long connectors the keyboard plugs into - if you have a fine pick or some dentists tools, or a fine...

I took it to mean "Black Box", though I realise the Q68 could also be in a black box - mine is. But a more expanded meaning - original QL case and using the original video circuitry. This allows for expansions within the case. Technically Qimi / Minerva / Hermes / QL-SD are all expansions ...
