A good video upgrading exactly this type of memory chips



I have it bookmarked as I'll be doing this on mine at some point, i got the chips from a 4mb falcon memory board as the chips were marked the same as in my ST.

You really need a diag cart and see what the output is via serial probably one or more chips not right.
