>>4275727a coolscan 4000 i recently got working..
bought a pile of scrap and replaced the firewire controller and power supply
the front is kinda duct-taped together as not to fall apart or allow dust to enter
pic related is a half-frame scan from it using the FH-3 strip holder
cleaned the mirror today and it really helped with the sharpness
you can actually see that it says "dong museum" on the sign, which you could not make out before cleaning the mirror
