The first one is an Apple High-speed SCSI card. I'm not aware of it ever
having a firmware update, but I don't have mine handy to compare the
label on the EPROM.

The second appears to be the same card but with an unlabelled or
reprogrammed EPROM and a less "finished" version of the card. It might
be a prototype of the card and could have pre-release firmware.
