'''You need :'''
*a "NEXYS2 500kgates" starter kit [[http://www.digilentinc.com/Products/Detail.cfm?Prod=NEXYS2]] (1200kgates should be better for future version)
*a "PMODSD" module for reading sdcard [[http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,401,513&Prod=PMOD-SD]]
*an alimentation (cause they don't give it with starter kit) [[http://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,393&Cat=3#DTSWPS]]

== Last news about this project ==
 
Future version will use NEXYS2 1200kgates, because last version of FPGAmstrad used 99% of 500kgates, and that I have so much things to add.
 
In september 2011, I have done research about USB Joystick, I plug it successfully on another FPGA project. Not tested on FPGAmstrad.
 
In november 2011, I merge several code (a better SD module and other small things), I debug dsk_select (the last amstrad disk was in fact not inserted, you had to put another dsk file on SD card to detect it...), I recode interrupt correctly (no real changes feel, perhaps a better speed feel), I pass VRAM from 16Ko to 32Ko (so crazy car II startup image is displayed fully) and I start a new way of implementation of VGA display solution that allow address derail [[http://quasar.cpcscene.com/doku.php?id=assem:crtc] "amstrad rupture"]
 
For the moment, I turn off sound so that I can continue coding on 500kgates, I hope buying a 1200kgates next days.
