Now I'm 6 for 6. All six work, all pass interchangeability. For those
keeping score:

3 Seimens model FDD 200-8P
1 Seimens model FDD 120-8
1 Seimens model FDD 100-8
1 Shugart model 801 (missing one cap)

Now to go through and jiggle all of the boards in the C3-D, power it up
and see if she boots. Wish me luck.
