while digging through my old stuff I came across this. it appears to be the parallel port add-on kit for SONY SCPH-9000 series? Looking at the installation instruction it seems fairly challenging - not to mention the photos are in B/W
Inline images arent working so I have added them as attachments... Always wanted one of these kits, interesting devices listed them on their website years ago but when I ordered they didnt have any unfortunately. They are fairly easy to install, it gets the majority of the signals from piggybacking the BIOS ROM.
