Hardware description:

• AlphaPC 264DP mainboard supports one or two daughtercards. Each daughtercard contains:
  • One Alpha 21264 microprocessor operating at a speed of 500 MHz
  • A 2MB or 4MB, 128-bit L2 cache with late-write HSTL synchronous static RAM (SSRAM)
• The 21272 core logic chipset on the mainboard interfaces to the CPUs, main memory, and PCI buses.
• SDRAM memory subsystem includes:
  • 128MB to 4GB memory complement with 72-bit ECC
  • Four memory arrays, each consisting of four 200-pin, 72-bit buffered SDRAM DIMMs
  • Memory speed support of 83.3 MHz
• PCI bus support(33MHz):
  • Five 64-bit slots and one 64-bit slot (shared with ISA slot)
• Integrated PCI peripheral support:
  • Integrated Adaptec AIC-7895 dual-port, ultrawide SCSI controller
  • PCI-to-ISA bridge using a Cypress 82C693UB hyperCache chip
• PCI IDE for two devices (PIO mode 4)
• Keyboard/mouse control and time-of-year clock
• ISA bus support:
  • One dedicated ISA expansion slot (shared with the 32-bit PCI slot)
• Integrated ISA peripheral support:
  • SMSC FDC37C665 combination controller chip provides diskette control (2.88MB), two serial port UARTs with modem control (550), and a parallel port.
• Daughtercard has onboard 5.0-V to 2.0-V voltage regulation for CPU, and 3.3-V to 1.5-V voltage regulation for SSRAM
  • The mainboard supplies +3.3 V
  • A separate power connector supplies +5.0 V
• Daughtercard has onboard flash ROM for 21264 Alpha microprocessor SROM support.
