I have an ancient Epsom GT-3500 scanner which still does pretty well
everything I want ok. I need a flat bed type for scanning things other
than sheets of paper.

However, I only use it with my RISC OS computer via the SCSI port - I
can't find any software/drivers that allows it to work with the PC via its
parallel port. I *think* it came with a PC SCSI card - but since I didn't
have a PC at the time long since gone, as is any PC software for it.

The problem is scanning old car wiring diagrams out of the handbook, etc.
If I do this in pure B&W - regardless of resolution and other settings, I
get a poor quality image. Scanning in grey gives excellent results -
except you can now see the paper 'colour' which often varies according to
how it has been exposed to daylight etc in use.

I could transfer the untreated image from the scanner to the PC, and I do
have things like Photoshop, but haven't really played with it much.

Any simple way to get a clean B&W image?
