Ok, thanks for some replies. I have CanonScan 9000F Mark II flatbed. It have optical 9600 dpi CMOS sensor with interpolation up to 19,200 dpi. Also, I will try HD microscope camera (40x to 1000x) someday. I have backlight pad for scanning.
I have some fiche films for technical manuals which are not in Bitsavers yet like DECserver 200 tm, CI 780 tm, etc. When I have scanned docs, I will send them to bitsavers. They can be useful for developing emulators. I read Al’s links (vintage computing forum), I was surprised to notice a lot of fiches about VMS sources. I was trying to find Avanti technical manuals (AS200/400) but found separately technical manuals like CPU, PCI chip, etc. because Alpha servers are based on PC architecture.

No read the thread I just posted The thread says: As you can see from 1ajs's 4800dpi example, even these could "nearly do". Also I think saving uncompressed 9600 DPI from 4800x9600 scanner may be much better. Could it be tried? I've calculated fiche DPI for posted DEC images (TA11 bootstrap), it's about 3200. 1110*16/5.75 = 3089 DPI You can add a few percents for margins. DEC crammed a lot of frames on a fiche sheet
