Re: [N8VEM-S100:1418] terminating the backplane...

[John Monahan <mon...@vitasoft.org>]

Traveling so this will be brief. I think the best approach may be a short (dedicated) card. It will use up one slot and for small systems that is a sacrifice. An alternative would be to reproduce the 100 pin connector on the top of this board so an extender board could be temporally attached. Not ideal and best would be a special half hight board.

Remember however these terminators do not work miracles most signals on the bus are at most a few MHz. If you terminate the pDBIN and pWR you help a lot as most other signals are long settled.

Having always-on open communication links through massive public servers I don't have control over seems like too much of an invitation to be infected by a virus or bot. It is bad enough that my Mac wants to stay in periodic contact with Apple's cloud. Skype was tempting before Microsoft bought them. There have been too many examples of remote session links being abused by vendor employees. Even "back to  my mac" makes me nervous. There was a recent episode where Apple cooperated with a social engineer and compromised someone's entire electronic persona. If you want to speak with me, calling me on the phone works well, and you don't have to wonder if the electronic mail got through or not. When I say "Hello, this is Doug", you know who you are talking to. Just in case you were curious.
