Expansion 'slot' on the back of the Amiga 4000

[Lunarnut]

Was there any hardware specifically designed to take advantage of this? Also - has anyone tried to mount the Cybervision PPC video out on it? Did it fit?

I think it was most commonly used as an external SCSI port. The Dataflyer4000+ is an example of one such peripheral. The SCSI module for the CSMK2 is another.

With a new backplate, I'd guess that the CVision video would fit, but having never owned one I can't say with certainty.

There were some cards that provided a external port (like SCSI cards) that used that port. Dataflyer for the A4000 (which converted the IDE to SCSI used it)
