Full Version: HP-85 ROM internals picture?

Has anyone got a picture please of the inside of an HP-85 ROM? I recall they look like a blob of epoxy with wires coming out, but Google can't find an image.

There are no visible wires it is just a blob of epoxy on a small printed circuit board with plated through holes along the long edges that provide connection to the ROM drawer. Under the epoxy blob the die is likely wire-bonded directly to the circuit board.
Thanks Martin!

Ah, yes - I have attached one reduced scale version of one of my images.
