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
