Wires are connected directly to the time chip. Cystal and 22M
resistor are in a small stripe board. Diode with a tantalum
capacitor in a separate stripe board:
All this barely fits inside HP-41C enclosure. Battery holder is
quite tight as wires go under the foil. Probably should use thinner
wire, same as used in connecting crystal and diode parts. But as I
have only two colors, that is how it is now...
