Offered here is an authentic Adaptec AHA-1510B ISA-to-Fast SCSI-2 host adapter, manufactured in Singapore during the mid-1990s.
This card was designed to add both internal and external SCSI connectivity to an IBM-compatible computer equipped with a conventional 16-bit ISA expansion slot. It is appropriate for a period-correct 386, 486, Pentium or similar vintage PC restoration.
The AHA-1510B can connect a wide variety of classic SCSI peripherals, including CD-ROM drives, tape drives, scanners, removable-media drives, external enclosures and hard drives.
The circuit board carries the shared family marking:
AHA-1510/20/22B
However, the factory identification label on the controller clearly identifies this card as:
AHA-1510B
It should therefore be identified and configured as an AHA-1510B—not as an AHA-1520B or AHA-1522B.
The circuit board was designed for several related Adaptec models. Consequently, some component positions are intentionally unpopulated on the AHA-1510B. This is the correct factory configuration and does not indicate that components have been removed.
The AHA-1510B does not contain a SCSI boot BIOS.
This means that a computer cannot boot directly from a SCSI hard drive connected through this adapter. A conventional IDE or other boot device starts the computer, after which the appropriate operating-system driver provides access to devices attached to the SCSI card.
That made the AHA-1510B particularly useful for adding non-boot storage and peripheral devices without paying for capabilities the computer did not require.
This adapter is suitable for connecting period-compatible devices such as:
As with any traditional SCSI installation, each device on the chain requires a unique SCSI ID and the two physical ends of the bus must be terminated appropriately.
The exact card photographed is the card being offered.
The circuit board appears clean and complete, with its internal connector, external connector, switch block, LED header and visible components present.
The metal mounting bracket and external connector have normal discoloration, oxidation and handling wear consistent with the card’s age. The ISA edge contacts show ordinary installation marks.
Please examine all photographs carefully. They show the exact adapter being offered and form an important part of the condition description.
The adapter will be enclosed in anti-static protective material, supported against bending and packed inside a sturdy shipping carton. Particular care will be taken to protect the circuit board, ISA edge connector, internal header and external SCSI connector.
Free shipping with tracking is included.
