Applications
ISA backplane boards like this one were the expansion hub of mid-1990s desktop PCs, physically connecting ISA and early PCI expansion cards to the system bus. The Compaq Deskpro 466 and Prolinea 466 were part of Compaq's mainstream desktop lineup in the early-to-mid 1990s, based on Intel 486-class processors running at 33–66 MHz. The ISA (Industry Standard Architecture) bus, introduced in the early 1980s with the IBM PC/AT, dominated PC expansion through the early 1990s before giving way to PCI; by 1994 most new systems like this one offered a mixed ISA/PCI backplane as the transition was underway. CMB (Compaq Memory Bus) was a proprietary Compaq interface used on some of its 486-era boards. This backplane is a direct replacement part for any Deskpro 466 or Prolinea 450/466 system experiencing slot or bus connectivity issues, and is also of interest to technicians and collectors maintaining Compaq 486-era hardware.
This Compaq 172622-001 ISA/CMB/PCI backplane board has been inspected and appears to be in good used condition. The board shows normal light wear consistent with prior installation; the PCB, slot connectors, and header pins all look clean and undamaged. It was pulled from a working Compaq desktop environment.
