You said don't mention those STE memory thingies so I won't :-), but are the chips on some of these not the same as ones used directly on a normal STF upgrade?
You could desolder them from those if they were the same?
(grabs one from a bag)
right the chips have on this one have 16 pins (8 each side) and look the same as the ones in an STF (if memory serves)
They are marked

& you need a resistor for each chip too if I remember right?
