Anyone out there other than me old enough to have run a 10base2 network in their home? My first computers 2 computers when I was in high school I connected together with a 10base2 with 50 ohm terminators and all that. My mom wasnt happy as I literally knocked a hole in her wall without asking her.

This was back when the internet was still fairly new so you would get on with 1200 baud modems to a BBS that would give you a piggyback onto the internet which you might be lucky to get access to for 30 - 60 minutes a day.

10base2 network card attached for prosperity.

Is it f(r)oggy outside?

Regardless of the weather, its froggy in here! This is another one of our coral finger #frogs, and I think they are so incredibly cute.

And they are always hungry. When we water the plants in their terrarium, they usually attack the jet of water. 😄

That would be everything for today. I wish all of you a great start into the weekend!

I sense that #BL602 HAL was revamped as "hosal" HAL ... So that it can accommodate #BL702 🤔
