Manuals for RiscCAD

I approached the author of RiscCAD to see if I could purchase hard copies of the manuals (there are two: User and Command). Unfortunately hard copies are not available. However, a commercial printer would charge about £10.00 for a single copy ie £20.00 for both manuals. If I purchase 5 copies, the price falls to around £6:00 per manual making £12.00 for both. Would anyone be interested in buying copies of the manuals? Please advise.
