CPC_RAM512K_V1.01

By Revaldinho

2 layer board of 2.90 x 2.35 inches (73.7 x 59.7 mm).
Shared on April 25th, 2018 19:13

Amstrad CPC 512K RAM Expansion using a XC9572 5V CPLD for all logic.

Status

  • First board received, assembled and CPLD programmed in-situ (via JTAG).
  • Memory passing basic tests with an unexpanded CPC464, timing seems fine.
  • DK'Tronics software detects board and reports all 512K in memory test on startup

This version fixes the connector pin-out to be compatible with MX4 Motherboards and standard ribbon cable arrangements.

For project and CPLD programming details see my GitHub repository
