BOMARC's business was ripped off in the past by scanners/resellers, so he now only sells hard-copies on colored paper with heavy watermarks right across them, so scanning/photocopying is not really worth the trouble for any would-be rip-off artist.

When I bought some from him a while back, I asked about some arrangement to make them more widely available, but he did not respond so I guess is not interested.

If buying, be aware that the schematics do not come with any explanatory notes - they are just connection maps with component types and some values listed. Still very valuable if you are looking at component-level issues.
