Brian, You're absolutely right - The original use case they were designed for likely saw no switch movement. Kindest regards, Doug Jackson em: d...@doughq.com ph: 0414 986878 Check out my awesome clocks at www.dougswordclocks.com Follow my amateur radio adventures at vk1zdj.net --

Thats awesome news. Sadly, that application is an abuse for that type of DIP switch - it is designed to be set and left alone inside a piece of equipment. Great to hear that you sorted it out. Kindest regards, Doug Jackson em: d...@doughq.com ph: 0414 986878 Check out my awesome clocks at www

Hmmm so similar to the LED activity while bootstrapping, but you're not trying to bootstrap. I wonder if it somehow thinks it's in bootstrap mode when it isn't. On Tue, Jul 7, 2020 at 11:21 PM RETRO Innovations wrote: > On 7/7/2020 9:39 PM, Josh Malone wrote: > > I've recently dealt with 3 T

[M100] TPDD logic board errors

Anyone have a service manual for the TPDD? With the assistance of a second unit that is working, I have determined the logic board has an issue.  On power, it waits for a bit and then just starts blinking the power LED.  Or, is there someone who fixes these I can message? Jim -- RETRO Innovat
