Thought I would document an odd SCSI controller card made by Hitachi based on Adaptec AIC-6360L controller and AHA-1520 Bios Version 1.4 (1990).
It is a 16-bit ISA card using 4 physical DIP switches for all settings.
I listed the functions that I could figure out. Sharing it here.
2 functions that are not clear to me:
SW3-5 / PRI - It posts a diagnosis error when ON.
SW3-8 / OWS - No idea about this function, no obvious changes when ON or OFF.
SW4 series seems to provide manual settings for DMA Data Request / Data Acknowledgment, not sure how to set those. Received the card with all switches OFF.
During POST, the card always seeks target #0, I only have Ultra wide HDDs available and was not able to get it to work using an adapter testing on a 386 machine.
The AIC-6360L controller is able to support up to 10 MB/s (SCSI-2) but I did not find a switch to adjust the transfer rate.
Hope it helps saving some time if someone ends up using this SCSI controller.
