Hayes Chronograph +WiFi Time

The Hayes Chronograph is a real time clock that provides time and date functionality to a vintage computer via a RS-232 serial port. A vacuum florescent display in the front displays the time or date along with the day of the week.

This Chronograph has been upgraded to include a WiFi Time module I created that makes it a stand alone clock. Once connected to a WiFi AP (2.4Ghz), it will contact a NTP server and set the time and date on its own– no computer required! Firmware can be updated over the air. A perfect desktop vintage time piece. The upgrade is reversible simply by removing the add-on board inside and replacing the original micro-controller back into the socket on the motherboard.

Additionally, this Chronograph was missing the back plate when I received it. In the interest of restoration, I created reproductions using 3D printing and laser cutting. It was also missing the power supply but I’ve sourced an original Hayes power supply (US grounded 120VAC plug). You’ll also receive a reproduction of the user manual as well as a one page user’s guide for the WiFi Time module.

The Chronograph was released in 1981. Not many were sold and it was discontinued shortly thereafter. Being over 40 years old, it’s amazing it still works as well as it does. I’ve done my best to test, repair, and refurbish this unit by replacing bad capacitors, fuses, reproducing missing parts, and in some cases, an entire VFD. I’ve had one running continuously in my office for nearly 5 years without issue. However, given the age, I cannot make any guarantees as to the longevity of the Chronograph.

Hayes Chronograph +WiFi Time: $750
