[Milsurplus] computer expert needed

[Tony Snider]

Hello,
I have some electronic manuals for a receiver system I am trying to get going and I cannot get them to open correctly.  I got them to open correctly yrs ago on a different computer but can only get the title page now.  a friend of mine was able to get them to open on his computer but of course he is in Ca. and I am in Va. the files came from the manufacture of the units. they are .tif format anyone out there got any ideas?? I can email these if anyone wants to give it a shot?? is there some special soft ware I need or can someone convert them to PDF. happy to pay for the service
Thanks
Tony
