Actually that 8bit scsi card is nearly same as a Rancho RT1000 Value Stor (same FCC ID) except missing the IRQ jumpers and the Term parts for the missing Ext connector. The NCR53c400 series was used on quite a few very early 90's XT/AT scsi controllers for HD or Cdrom. J6-J9 are the IRQ, J1-J4 are the BIOS address. It supports bothe HD and Cdroms with the proper BIOS (yours may actually support them both too). Here is a pic of one that works very well and is same as yours but the full card. They work great to add a scsi HD or cdrom to an XT/AT and still stay somewhat period correct. Save that card or offer it to me 😀
added: the label on the BIOS looks like 1999 but is 1993...
Ofc I'm gonna test it, I think I might have an old quantum SCSI 80MB drive somewhere. Since the original hard disk in my Philips P3105 is near dead (Miniscribe 8425X with 30% bad sectors, growing) this could be a nice replacement 😀
Stuck at 10MHz...
