The Obsonet (Reloaded)
The ObsoNET is the first network card created for the MSX. In 2004, the hardware designer Daniel Berdugo and software developer Nestor Soriano joined forces to create a cartridge to bring ETHERNET standard to the MSX line of computers.
The cartridge is based on the Realtek RTL8019AS chip and uses a flash memory to host and execute a BIOS that allows the use of network commands from the Nextor operating system (compatible with MSXDOS). An EPROM stores basic configuration data for the RTL8019AS chip and a side connector is used to plug a network cable to your MSX. A GAL16VB is used to implement the logic required to activate and expose the cartridge to the computer.
The original version of the Obsonet was designed to fit a standard Konami cartridge case. This project implements a new version of the cartridge that fits the standard Patola cartridge case available in Brazil as well as the standard Konami cases available from multiple vendors WW.
