the sockets are going to be trickier. i'm thinking i need a soldering iron tip that can hit all the pins at once. did a web search and the 5th result was MY OWN DANG TWEET from like 2 years ago, lol. i think i just "Fooned" myself.
@tubetime when I was a kid and new parts where out of reach, as well as a desoldering pump, I used this 👇, googles and an old jacket. Melted the solder in a region and hit my hand with the PCB on the table, with the parts side down. Inertia did the rest...
so this board looks like it does both XMS (extended memory) and EMS (expanded memory). expanded memory is banked and uses a 64K (iirc) window to access it.
@tubetime how do you go from PCB layout to schematic? When I did this, I ended up tracing the PCB in a CAD package, the writing a thing that analyzed the lines and spit out a netlist. I then learned that while many tools exist to convert schematics to netlists, I couldn’t find much to go the other way ‘round.
@keelan i'm running a trace in layout, seeing where it goes, then creating the connectivity in the schematic and pushing it to layout to create the connection.
