This thread is actually quite scary. Back in 1990-ish, when the Classic would have been a modernish computer, transferring a PICT to a PC or Unix box would have been moderately painful. Software like MacLink made it a lot easier but the PICT format was supported by the majority of graphics packages. You may have had to transfer the file using a serial cable if you didn't have DOS Mounter or similar.
During the 1990s, this transfer would have been very straightforward. PC Exchange (in conjunction with a free copy of MacLink supplied with Mac OS) handled it all. Is it really so difficult today, or have we already started to lose old Mac knowledge?
