I'm almost finished with the backplane project, but
I have a few questions first.
For the fuses, I was wondering what the values are?
I figure for the +/- 16VDC 3A should be enough.
For the + 8VDC. This would be set above the current
draw for all the PCB's on the bus. I'll start out at 10A
or so... Or if someone has a recommendation...
My other question is, what is the calibration procedure
or purpose for the 2k pot ?
BTW: The Mouser S100 connectors fit spot on! Everything aligns
fine, the pins are long enough for this thick sturdy PCB & the
mounting holes match up. At 8 bucks or so per connector, not bad.
The only thing is the slot tabs are not gold plated.
I purchased a new digital camera for the girlfriend (an x-mas gift) So
I took it out and played with it. Here's some pic's of the backplane
board and my Imsai.

FWIW: You may use any/all pic's I post for other purposes.
Thanks !
