== A 512KB RAM Expansion for the CPC 6128 and Plus. ==
This is a DK'Tronics compatible 512K RAM expansion board built using standard 74 Series logic ICs and a single SRAM chip. There are no devices which need programming and all parts are in through-hole packages to make for a board which is easily assembled even by a beginner.
This card supports all 6128, 464 Plus and 6128 Plus machines but is not suitable for the older 464 and 664 computers.
The board is fully compatible with the DK'Tronics/Amstrad bank switching schemes described in the DK'Tronics Peripheral Technical Manual.
The card has a Mother MX4 standard box connector rather than an edge connector. So to use the board you will need a Mother X4 or compatible expansion card.
This is a fully open source project and all code and more documentation is available on the project's [https://github.com/revaldinho/cpc_ram_expansion GitHub pages] and [https://github.com/revaldinho/cpc_ram_expansion/wiki/CPC-512K-RAM-Expansion wiki.]
The bare PCB is available from SeeedStudio via their [https://www.seeedstudio.com/Amstrad-CPC6128-512K-RAM-Expansion-Card-g-1136535 Seeed Gallery pages].
Bare PCBs or fully assembled cards may from time to time be available also directly from Revaldinho - please PM via the Discussion Forum to check.
