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
