Up for sale is a rare vintage 1984 CompuPro M-Drive/H Disk Emulator board. This board was designed for S-100 bus systems to act as a solid-state RAM drive, significantly speeding up disk operations in early microcomputers.
Board Details:
This board is being sold as-is, untested due to lack of compatible S-100 testing equipment. The board appears to be in good physical condition with no obvious burnt traces or catastrophic damage. All socketed chips appear fully seated. The gold fingers on the edge connector are intact and show normal wear from insertion. Please review all high-resolution photos carefully to assess the condition of the components and traces before purchasing.
