Re: Unable to get SIO card working

I have found on my setup that the stacking connectors are particularly sensitive. Sometimes I need to play with the stack to get it working properly.

Subject: Re: [Z80MC] Unable to get SIO card working
?
Hello Josh,

I think I connected my multimeter correctly, I put it between the FTDI cable and the terminal on the side, and I ended up measuring ~70mA with the SIO and CPU cards. I tried out the other combinations and got 80mA with the Front Panel connected and 56mA with all cards connected.

Unless I made a mistake connecting it looks like its low instead of high. I did find out however that if I have the Front Panel connected and I hit the reset buttons (F and 0) on there the SD card LEDs will flash. So that's something at least.

Thanks,
Morgan
