A full length Zorro II SCSI card, which supports autobooting if Kickstart 1.3 is present. It has a 50pin internal SCSI header and what appears to be a DB25 external SCSI connector. It does not appear to adhere to the Commodore RDB (Rigid Disk Block) standard as it will not boot from a FFS volume. It has to be setup similar to the old A2090a if you wish to use FFS.
The card uses the WD33C93A-PL SCSI controller made by Western Digital, has a 3-pin header for an LED (JP1) and a 3-pin jumper to enable or disable autobooting (JP2, possibly labelled Kickstart 1.3 or 1.2). The unpopulated SW1 marking connects to the JP2 pins 1 and 3 with no obvious function. The SW2 position pins have no visble connections. An unpolulated JP4 has pins 2/3 directly connected by a trace.
This card has been reported to be incompatible with the A2620 and A2630 accelerator cards.
The board has 3x socketed SCSI termiantion packs (SIPs) which are removable.
The U6 PAL is a TIBPAL16L0-25cn, with label: P95-01309
The U11 PAL is a TIBPAL16L0-25cn, with label: P95-01602
The board has a 10MHz clock for the SCSI controller chip.
Two EPROMs provide the autoboot driver.
The board has silkscreen markings for Comspec, Toronto, Candada
