Posibus to Negibus Converter
- dw08a2s is a two-sided board based on DEC's DW08A Posibus
Converter backplane.
- dw08aholes is a version of dw08a2s with un-needed cutout holes,
and only 6 mil traces (too thin).
- dw08a is dw08aholes with the power traces beefed up, and is
the version that matches the prototypes. It has a mechanical interference
fit at the right edge.
- dw08aRev2 is a version of the dw08a backplane with the
interference fit fixed, and the un-needed holes removed.
- dw08aRev3 is a version of the dw08a backplane that fixes another
interference fit, having to do with the backplane being more than 3U tall.
- dw08a4lyr is a four layer version, with all the traces
beefed up.
