Finished up the Real-time Clock module and the ESP-8266 Wifi module. The only uncomfortable part was getting the ESP board soldered to the surface mount pads. Managed to get it done, but it was a bit finicky, and not super clean 😬

Good news is the clock module works and the #RC2014 now knows what date/time it is ⌚, and I was able to login to the web admin interface on the Wifi module to configure it 🛜 🍻

Assembled the CF card module for #RC2014, but on boot up the system hung while trying to probe it until timing out and continuing to the ROM boot prompt. With help and suggestions from Spencer and others on the rc2014 forum, I was able to use a multimeter to probe all the CF pins and found one that didn't have a connection. A careful application of the iron to the surface mount for that pin reflowed the solder and made a good weld. Rebooted and all's good. 🫡

A photo of the current state of the RC2014 build with the newly inserted pink CF card module in good working order. The other modules installed are the purple Z80 CPU, the blue SIO/2, the green 512k RAM/ROM, and the red Dual Clock modules. The colors of the Zed Pro Pride's rainbow are coming together.
