ECLair

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
• 8-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
