part# H2004-ND Hirose Electric Co., A3B series 10-pin dual-row, 2mm connector (HP 100/200LX)

part# H9999-ND Hirose Electric Co., socket terminals, quantity 100

part# H2013-ND Hirose Electric Co., A4B series 4-pin, single-row, 2mm connector (HP-48, HP-95LX)

If you already have the HP cable, it comes with an adapter to plug the 10-pin connector into a 4-pin 95LX or HP 48 calculator. One clever use of this adapter is use it as a mold to make a bump on Digi-Key 10-pin connector using 5-minute epoxy. This bump is not essential, but may help prevent you from inserting the connector upside-down.
