Re: looking for an S-100 expert builder to build and test prototype board

Woo Hoo!  Two volunteers!  That's great!

I've uploaded the KiCAD file set, schematics, and PCB layout to the
N8VEM wiki here:


OK, so we've got a design and builders to put it together.  This is

Does anyone want to pitch in to get some prototype PCBs made?

Typically that's $150 for 5 PCBs at http://www.33each.com

You don't have to pay for it all or even build a board if you want to

If you buy a board I can send it to one of the volunteers.

Please remember though this is a high risk venture and no guarrantees
it will work.

However, I think there is a pretty good chance and if we spread the
risk and work out a bit everyone benefits!

Thanks and have a nice day!
