Hey John,
#1 as to google groups, I don't know. My normal "mode" is corporate email with outlook. With groups and gmail I'm all thumbs. Sometimes I'm replying to all, and other times I'm just emailing the individual.
#2 Is you whole kit built?? I started with the usb cable into my laptop and ran Tera Term. I had to look in my windows device settings to find what port it installed the usb on. The when you first fire up Tera Term is will be at 9600 baud. Change it to 15,200 and you'll see the logs. Maybe you've already done that??
Then the unit will start creating and broadcasting itself as an access point. You if you scan your WiFi list on you laptop, you'll see something like imsai8080 as an access point. click and log on to it the ssid password, is password. the open a browser and if on a pc, go to 192.168.4.1 it will open the gui. If on a mac, If on a mac, type imsai8080.local in the browser window..
After you are into the gui, you can open the sys: and edit the name in the datat in the SSID and PASSWORD location to your wifi. The if you do the reconfiguration with the reset switch and switch 3 is up, it will connect to your WiFi and if your laptop is on the same wifi, you can access it with the rest of your network. I had to run a port scanner to find out it's ip address as I have some 25 ip addresses handed out.
So, did you receive the plastic blocks to align up the LED's. or are you still building??
Good Luck
