Is the 250407 the only one with narrower DRAM chip spacing?
I checked motherboard images from the web. By measuring from the images it
looks like it.
I only got 250407 & 250425 8 DRAM chip motherboards.
I made a new SRAM board which is designed for 466&469. It also works in
older models by changing two resistor positions and soldering 6 extra
wires. With flat pins it also fits 407 if the pins are bent slightly and
sockets are leaf spring style.
