Progress

• Wire-Wrap board has been completed and tested through EPROM, NOP loop runs our system.

• Schematics have been created for HC11, Memory, and CPLD.

• Vender for Pulse Oximeter has been researched and selected.

Time Chart

Contingency Plans

• Unable to get Fingerprint module working– Use keypad for authentication

• Unable to get Bluetooth working– Use wires to connect the devices

• Unable to get PCB boards working– Build a second wire-wrap board
