At the top of the third section of the download list (Install Media) is an item "M-series and T-series Install Media <https://download.juniper.net/software/junos/8.2R2.4/install-media-8.2R2.4-domestic> ". This is what you need to create a PCMCIA boot card.

I've also successully used WinImage on Windows to write the install
image to a SanDisk CF card followed by putting into a PCMCIA adapter
then into the router to boot from.
