Just tried to attach a picture of the card ...


Well, don't oversize that photo, takes away all the fun...

That a switch on the backplate? Or a cinch connector?

On second sight, that card looks like it's got an 8 bit ISA connector. Plus some sockets for glue logic and possibly an EPROM pair - that's an ALF style HDD adaptor for maybe a WD1003/1004 controller board.:juggler:

@Effy

ALF was before SCSI became popular, so it used ST506 (MFM) controller boards (like the 1003/1004 mentioned above). The ISA cards were bootable, but of course not on the Amiga without special boot ROMs which only the latest ALF cards got (predated Kick 1.3).

To make use of that card you'd need to fill the empty sockets with most probably some properly programmed PALs & 74xx. Boot ROMs would be optional but need to match the card (alternatively a set of drivers to boot off a floppy). And of course a supported ISA card.

And now we want to see the ebay photo - proper resolution please. ;)
