Alpha Micro AM-715 4MB Memory Expansion Board REV B DWB-00715-10 DWX-00715-10
The Alpha Micro AM-715 is a 4MB proprietary memory expansion board designed for Alpha Micro computer systems. This REV B revision of the board populates its full complement of DIP DRAM chips across the PCB surface and interfaces with the host system via a multi-pin proprietary edge connector. The board carries the Alpha Micro "Made in USA" designation and dates from the mid-to-late 1980s era of Alpha Micro minicomputer systems.

Applications
Alpha Micro was a California-based manufacturer of proprietary minicomputer systems active from the late 1970s through the 1990s, producing multi-user systems running their own AMOS operating system. The AM-715 memory expansion board is a proprietary memory upgrade card designed to add 4MB of RAM to compatible Alpha Micro systems, expanding system memory beyond the base configuration to support additional users and larger application workloads in multi-user environments. Alpha Micro systems were used primarily in small-to-medium business environments for vertical-market applications including accounting, manufacturing, and professional services. These boards are now sought primarily by maintainers of legacy Alpha Micro installations who need to expand or replace memory in aging systems, as well as collectors of vintage minicomputer hardware. Because Alpha Micro used proprietary bus architectures, this board is not compatible with standard PC-bus systems and is only suitable for use in an appropriate Alpha Micro host chassis.
This Alpha Micro AM-715 4MB Memory Expansion Board (REV B) has been inspected and appears to be in good used condition. The board is clean overall with no visible cracked traces, broken pins, or damaged components. The DIP DRAM chips and solder joints look intact across the board. The edge connector pins show light oxidation typical of stored surplus boards of this era. A warranty-void sticker is present on the connector end. No accessories are included — board only.
