The kit worked first time.

This was easy to build thanks to clear and detailed documentation. It even include 4 output lines and 2 input lines that can be used for other purposes. The only problem I had was figuring out how to use RTC.COM program in CP/M to set the time. After some experimentation I discovered that 2 digits are needed for the day, month, year, hour, minutes , seconds and the day of the week. With the backup battery fitted, it is keeping good time - the date and time was bang on even after my CP/M system had been switched off for the last week.

Excellent RTC Module

I've been looking forward to a RTC module for this bus layout and I am not disappointed! Versatile design as usual! Looking forward to more colors, gonna get a black one and a white one, too!
