Actual chips used NCR53C96. Observe closely that both rows of each SCSI connector has pins connected.
Yet according to some, half of the 50 pin connector on SCSI 2 controlers were always grounded. Never connected. No change at all from SCSI-1 to SCSI-2 cables. Not that SCSI ever formally defined connections.

It's no wonder SCSI-2 is described as "obsolete". Even for people making genuine 16 bit SCSI bus controllers, the moment somebody plugged in an external drive, the whole lot ran at the slower bus rate. People making devices that could talk at higher speeds always had the devil's own time demonstrating that it actually did so unless plugged into a suitable controller.
I guess the real acid test would be a solid state card box, with a 50 pin and 68 pin connectivity, that actually had a screen that displayed what sized data bus it was currently using. Also the throughput data rate, that would be nice.
It's not going to happen with this device, but a Hat might be doable.
Tricky part is getting it visible from inside a case... er...
