ECB Developments

Updated - 4 Oct 2018.

ECB 2650

  • CPU - Signetics 2650 running at 1MHz.
  • ROM - Up to 8K of FLASH. I have tested a 1K ROM with the original PIPBUG V1 and a 2K ROM with PIPBUG V2 PIPLA.
  • RAM - At the moment 32K (minus ROM size), with paging a possibility later.
  • I/O - Hopefully interfacing with existing ECB interface cards.

Current State.
