I do grow crops on it.

Mine is 8100. Everything I was looking at, at that time, could only handle half at best.

My problem with them was they never seemed to be able to handle a yard large enough in order to justify their price.

Been following them for a bit, was going to build one a few years back, but instead bought a riding mower to pull double duty on teaching my daughter driving skiils

I would imagine you could host a BBS on them. Doubt it could handle many if even concurrent connections
