Wasn't that a matter of just soldering the chips in place? Not sure, but check your mainboard to see if that might be the case...

Forgot to mention:
The ST 512K RAM upgrade notes are in the ST Service manual on my website (handwritten additions, it is simple: just a resistor and two RAM IC's, the PCB is prepared for this).

And now the description is online in English on the diy page.
Based on a dutch description in MCWF nieuwsbrief 38, also online at my website at the books and magazines page. So the description was already available in dutch.
