Amstrad CPC RAM Expansion

The main event in this GitHub project is a 1MByte RAM Expansion card for the Amstrad CPC computers from the 1980s.

CPC RAM Expansion Cards: 'Old School' CPC6128 512KB and 1MB RAM Expansion Cards

• Two cards specifically for the 6128 and 6128 Plus and created entirely with standard 74 series ICs
  
  • 512KByte version
  • 1MB Version

CPC RAM Expansion Cards: Universal Amstrad CPC RAM Card

• Two Universal RAM cards, compatible with all Amstrad CPC computers providing full 6128 compatibility on a 464
  
  • 512KByte version
  • 1MB Version

CPC 4 ROM Expansion Card : CPC Fourrom Card

• This project is a CPLD-based ROM expansion board. Although only 2 sockets are provided each can be filled with a 'double size' EEPROM to provide the equivalent of 4 classic 16KByte Amstrad ROMs.
• The board will co-exist with other ROM cards and uses DIP switches to enable or disable ROMs individually and to select how the ROMs on the card will be numbered to avoid clashes with other cards.

CPC 6 ROM Expansion Card : CPC Sixrom Card

• This project is a CPLD-based ROM expansion board. Although only 3 sockets are provided each can be filled with a 'double size' EEPROM to provide the equivalent of 6 classic 16KByte Amstrad ROMs.
• The board will co-exist with other ROM cards and uses DIP switches to enable or disable ROMs individually and to select how the ROMs on the card will be numbered to avoid clashes with other cards.

CPC Expansion backplane

• The two 4 slot cards are identical apart from the pass through connector being replaced by an reproduction of the Amstrad CPC edge connector. This is useful if you need to use any legacy edge connector peripherals as well as the newer MX4 slot types, and particularly for CPC464 users who may have a DDI-1 disk drive controller or DDI-3 USB interface.
• The expansion slots on all cards are fully compatible with modern Amstrad CPC Peripherals such as Duke's M4 Card, the X-MEM RAM/ROM board and of course the RAM, ROM and Z80Tube expansions all described in the GitHub repositories here.

All of the above projects have been built and tested.

Eagle PCB files and zipped archives suitable for getting boards made are included in the Eagle Releases subdirectory.

Merci Revaldinho !

Grâce à tant de générosité, on peut acheter sur eBay des extensions RAM ou ROM à 40/50€, des MotherBoard à 40/50€, des PCB nues à 15/20€ ... Tout ce dont on était préservé sur notre machine depuis la MegaFlash... Trop généreux !

Vive les projets libres*. Vive le retour du business retro sur CPC !!!

* Ha oui, "on" est pas responsable de l'usage ni de penser aux conséquences...

Et tu fait quoi de tout ceux qui se la fabrique eux même et que tu ne vois pas ?

statistiquement c'est anecdotique, sinon vous n'auriez pas vendu des centaines de cartes, faciles à réaliser pour certaines

bon après si on les retrouve avec une marge sur ebay c'est que ça ne produit pas assez en amont

si y avait eu plus de dispo sur le dandanator, zaxxon n'aurait pas fait son coup de vendre le mini au prix du gold toutes options
