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 With as much de soldering that you do, I'm surprised you don't' already have one.

@tubetime with Stannum melting at 157 °C (100 Pi F), you *should* be able to just dunk the populated PCB into a deep fryer at 180 °C (356 F) and all the chips would just fall out?

routed (except for a few RAS and CAS lines). i also have the schematic, but it needs cleanup work.

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.

@tubetime RSVP all those legless chips. May their logic live on in the schematic, and in your future clones of their board! |

Some decades ago I filed a 16 pin DIP desolderer from a lump of copper , with a bit that fit a normal soldering iron. Not hugely sucessful as the irons I had then didn't really have enough power to get it hot enough. The cut all the pins off and desolder one by one method won in the end.
