i've got a kit with two ribbon with male DIL connectors at either end, one for IC29, one for IC22.
then a plastic casing with 4 small ICs. i will have to go through the BOM later and check off.
board is v1.3 - and i got it from you ages ago - Feb 2011 :-D only 8&1/2yrs to get round to this...

DONE. dougie fresh you're on.
i cracked on in the meantime, cutting out the 28-pin DIL. boy, that IS a messy job.
took great care with that - and i would say NOT to cut any pins themselves, because
it doesn't leave anything to pinch with pliers as you desolder them.
cleaning out the holes was tricky, until i figured out the correct way to do it.
i've learnt something today (please correct if wrong): desoldering braid/wick:
you're supposed to use that with flux, aren't you? at least that's what proved effective:
dip it in flux, and then when heated, the solder flows into the braid as it sizzles.
this seemed to draw the solder out of the holes. completed with a little poke with a
sewing needle. what the correct way to do this ?
that was actually my problem this morning/the other day: my soldering iron was covered in carbon.
it needed flux and a bit of a clean (small metal file).
i think i need a bit of a tutorial about proper solng practice, tbh ;-)
new DIL back in, re-seated the old eeprom, and... it still works !
cleaner job this time (we won't talk about the other one, but it's ok, want to leave that alone now).
so that's the mainboard modification completed
Q: what is the spare white header/connector? CN5A ?.
