SHAOSI've just received 3 PCB of "Germanium NAND" from oshpark.com
It was drawn in gEDA "pcb" software (images generated by OSHPark service):
and represents this schematics:
Also I got 3rd (1958) and 4th (1959) editions of "Transistor Manual" from General Electric Company with more schematics of computer components utilizing germanium transistors:

Very nice work guys! Don't forget to file off the breakout stubs :)
Are you sure? yes | no
*drools*
On my side, I think I have bought too many Ge transistors. If this is possible. A clock might need 100 or 200 transistors but I only have max 100pc of a single reference :-/ there will be some "designing" to do to keep a FF down to 2 transistors but the typical gate you have shown has many analog parts, which cost as much as transistors...
Are you sure? yes | no
Capacitor 470 pF and resistor 1K are optional and not required for slow parts...
