That is a real scsi card.
Looks like this

Now you can daisy chain up to 8 suitable scsi devices.

From my vague memory,(because of high proprietary fees?) I think HP
was the first to bring out a proprietary single device scsi for their
scanners(D25 format) and Iomega (and others?) followed. Iomega zip
drives were very popular at the time as they filled a wide hole in
sneaker net transfer*. Popularity lasted until 'the click of death HW
problem' developed.

Buying an Adaptec card was always expensive but the drivers/bios were quickly included in Linux. Finally a few cheap alternatives arrived
from Asia but you had chase the drivers/bios for a few years for them.

*A common internet connection at that time in Australia was a 300 baud
datel line.
