Subject: PC532 - Drilling Extra Mounting Holes, + PCB Layer Schematics
To:	pc532@daver.bungi.com	george@wombat.bungi.com

- I'd like to support my PCB more comprehensively, particularly around the
  CONN 1 area, as supporting my valuable PC532 on just 6 non optimally placed
  pillars (even if standard PC/AT placing) worries me.
- I would like to drill extra support holes in the PCB at some or all of:
  the corner near R3, end of CONN 1, end of CONN 2, corner near CONN 11,
  between CONN 15 & 16 @ both ends, both ends of U6, end of U13.
- Drilling matching non PC/AT standard holes in my chassis would be work well
  worth doing, giving me peace of mind when I lever in & out stiff scsi
  connectors &/or ram slices.
- I would prefer to use extra pillars screwed into both PCB & chassis because:
  - Glueing pillars on to the PCB would be cludgy, & only good for insertion,
    not extraction.
  - Self adhesive backing pads are too squashable.
The Problem:
- I don't have artwork for PCB layers, so can't see where internal traces/tracks
  run. I guess some of the places I've listed may be impossible to drill.
- Have schematics of PCB internal trace layers been released ?, 
  perhaps as paper copies, or anon ftp'able gif files etc ) ?.
- If not, perhaps George could list safe (x,y) drilling coordinates ? Thanks.
