ECLair is a long-term project to build an ECL minicomputer.

Project Status

  • 2012-11-24: Basic ideas/architecture starting to get put together.

Architecture Overview

  • MECL-based
  • 25MHz main clock
  • 16-bit data width
  • 24-bit physical address, 16-bit virtual address
  • DMA support (at least for front panel, maybe one other DMA channel?)
  • Microcoded, running control store in SRAM for speed
    • Unless I can find equally-fast EPROMs
    • Copied to SRAM from EPROM before the system starts
