Tuesday, December 11 2012. Console › Colecovision
This board is made to be used with one ColecoVision ROM file (up to 16Ko). For the moment, only one file can be stored to the EProm (no bank switching or bank selection). The attached package contains the schematics and PCB file (Eagle 5.0). Usage Just 'flash' one 2Ko, 4Ko, 8K or 16Ko files to […]
This board implements the F8 bank switching method to be used with 8K A2600 ROM files. An extra two 2-positions dip-switch is used to select a 8K portion of the 32K Eprom. This board is based on the F8 bankcswitching design: http://www94.pair.com/jsoper/bankswitch_f8.html Files A2600-ROM.sch : […]

Here is a very simple ZX81 modification to replace the ugly modulated video output by a composite video signal. I tried several modications from the WEB, but due to special video standard in France, none of them was successful on the ZX81. So, here is my own adaptation. If it works for me, it […]

Wednesday, September 1 2010. Graphical routines
The goal of this toolkit is to provide a set of graphical routines that are independent from the hardware. It can be typically used wherever SDL library is available (PSP, GP2X, ...) and Linux. It can be used to manipulate low level graphics (circles, lines, text, ...) but it can be also used to […]

This application is a graphical frontend to the "Connect 4" game, made by a very good friend (L. BUCHARD) in 1998. The goal is to be the one who creates a line of 4 tokens. That looks pretty simple but winning against the computer is a real challenge. All the information and source code […]

This simple tool is used to communicate between two dislays (X11 based), in both textual and graphical ways. It is a kind of an old fashion "chat" tool. The application opens at the same time two windows, both on the local host and on the remote host. Each user can type some text or draw […]

Here is an easy to build IR remote control. It could be used at home to control lights, radio or more powerfull things. This remote control is build arround an IR coded transmiter and an IR receiver powered by its own power supply. This architecture is based on a PIC16F84 (ou 16F628). I also build […]
