So I have imaged the three disks I found using

Then I scanned one of the manuals. UCSD Pascal :
http://storage.datormuseum.se/u/96935524/Datormusuem/UCSD-Pascal.pdf
The problem is that manual has text in red/brown and black. I scanned
it in colour. However the actual colour of the scan varies a bit
between pages. (Maybe because there are two sensors, one for top side
and one for bottom side.)
And the scan get very big.
Is there a way to create filter this pdf to use three colours and
possibly compress it better? What is the best way to deal with scans
of documents with coloured text. I know many DEC manuals that has
coloured text as well.

I use Acrobat Professional to both scan, OCR and optimize PDF's. It
works very well. I do this for many vintage manuals that had been
previously scanned that I've downloaded that have not been OCRed or
optimized. BTW: OCR works best when the manuals are scanned for color
or grey scale at 600bpi or better.
Cheers,
