I've build a FreHD and trying to connect it to my TRS-80 Model 1, but it's not working. Can someone with a working FreHD help?
I'm made both, the FreHD and the Model 1 adapter.
If you connect your FreHD to a power 5v power supply with the SD card inserted but without connecting the FreHD to your TRS-80, what is the behavior of the LEDs?
When I plug 5v into my FreHD, the red LED stays lit and the green LED stays off. Is this expected behavior?
If I plug my FreHD into my TRS-80 with the 5v disconnected from the FreHD, I see 2.6v on the FreHD 5v rail when I power on the TRS-80 & IE. Is this expected?
This makes me think that maybe my Model 1 adapter is not wired correctly. It would be great if someone else could check this on their FreHD.
