I am in the UK but I have two optical tape

read tape in reasonable quantities from any one in the UK. I can also
copy if required.
But the question was scanned images which might be available after the
tape has degraded and can't be read.

Hi I have a high speed reader to but I've had troubleswith rubber bands.
They leave gunk on the tapes andlayers stick together. On a high speed reader, itrips the
tape before one has a chance to stop it. Mine is a parallel one and I just connected it to
theprinter port ( guess that dates my laptop ). A simpleprogram reads the data and puts it
into files. On making a reader, the ideas of using a pile ofphotodiodes to read a punch
card doesn't makemuch sense. It might be better to have a LED lightat each hole
position of a column and a single photodiode.One could then just sequntially drive the
lightsand detect it with just one photodiode.One might need to aim each light at the
diode.As with Dave, if someone has fan fold paper tape toarchive, I could do an reasonable
amount. I'min San Jose, Ca, USA.I'm not setup to handle spooled tape safely.Dwight
