OK all you hardware hackers out there, how do I take my Dr. Dobbs 512KE
Mac and add another 512K to it?  I want to do it MYSELF, and am
certainly not above piggybacking RAM chips (with chip-select leads
hanging out), and adding a fan.  I don't have schematics, and am not
familiar with the decoding details.  It can't be TOO hard!

By the way, any info on 2Megs wouldn't hurt either!
Alternatively, any info on *inexpensive* ram upgrades would also be appreciated.

ANY LEADS?

Ad THANKS vance.
