Sumo AT/Storage Plus AT SCSI Host Adapter (version 2)
Note: Early versions of the SCSI-AT had the Option Jumper Block placed horizontally where the SCSI IC is on this later version, and the Interrupt jumpers split into two blocks. CN2 (the Internal SCSI connector) was placed vertically near CN3. The jumpers are functionally the same.
Default settings are in Bold or are selected by a

IRQ: Interrupt Selection: 3,4,5,10,11,12,14,15... Jumper the Interrupt you desire
to use. The default is IRQ#14. If no Interrupts are desired, don't jumper any. The Manual

IRQ#14 for an AT class computer.
