Thank you for your kind reply
Reader is:
MICROFICHE READER MODEL SC01-E
SERIAL NO. 4573
MAGNIFICATION 42x
VISIDYNE INC BURLINGTON MA USA
UK model (yes I'm in the UK)
230 VOLTS AC 50/60Hz .75 AMPS
Only Hi res setting works.
Using my home made but clean fiche holder the few fiches I looked at
seemed OK.
When adjusted for sharp focus the text was clear but a bit small.
