Hi again,

I got a box of 50 (!) RCA CD4001BE chips, NOS parts. They were just thrown in the box without any kind of static protection, but at least the ones I tested survived the ordeal.

So I changed U8. Initially I intended to add an IC socket, but the chip is under the base of the printer and there isn't enough clearance. Its amazing in a box that big to have tightly packed components.

Anyway I soldered the 4001 directly on the PCB and now the printer works fine.

I am attaching a picture of my new and fully working HP-46!!![Image: HP46-LR.jpg]

All the best
