Where can I get a compatible serial port connector?
EduCALC sells a cable with the appropriate connector at one end and bare wires at the other. For those who want to make a cable from scratch a contact and part numbers follow. Digi-Key Corporation 701 Brooks Ave. South P.O. Box 677 Thief River Falls, MN 56701-0677 800-344-4539 800-DIGI-KEY 218-681-6674 218-681-3380 fax $25.00 minimum order or $5.00 handling charge 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 HP95 or HP48. 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 it may help prevent you from inserting the 10-pin connector upside-down.
