Borrow a laptop and a flatbed scanner that can scan transparencies. Even a second hand Epson 4870 Photo will do. Just make sure that the transparency backlight in the lid is functional.
If I was going to make a trip like that, I would make a meal of it and make sure the images were permanently captured without distortion and with the minimum of fuss.
In addition to the scanner itself, there is special software that comes with the scanner called Digital Ice. It automatically locates hairs, fibres and scratches on the transparency and takes care of them. If you use that function, you are looking at long scanning times though.
In tests I have done here with small X-ray films, I can get good resolution images from scans of those films on my scanner. That’s just by putting them directly on the glass and scanning at 600-1200 dpi.
The scanning dpi is very important. Do NOT select ‘scan fo web’ even if your final intent is to publish those online. You must scan at a high resolution with a small amount of sharpening. Do the rest in Photoshop.
I will post an image of a scanned mammography test film. Mammography films have very high definition because the radiologists are looking for tiny calcific densities that may indicate a malignancy. If your scanner can scan one of those mammography test films, it will certainly do a good job on micro-film.
By the way, I have used microfilm readers and printers. That was when I worked in the anti-fraud department of a major credit card supplier in South Africa. If your microfilms are anything like the ones I was dealing with, the Epson 4870 will easily be able to scan those.
Here is the mammo film resolution area, scanned on my Epson 4870. The actual size of that image portion is less than 2cm.
