1chipMSX

Even though it lacks a 3.5" disk drive, disks are supported through emulation on a memory card, including support for booting MSX-DOS. Due to its VHDL programmable hardware, it's possible to give the device new hardware extensions by simply running a reconfiguration program under MSX-DOS. The "one chip-MSX" is equipped with two USB connectors, that can be used after adding some supporting VHDL code.

• Name — 1chipMSX • Type — Home computer • Release Date — 2006 • Discontinued — batch 1 completed • Cpu — Zilog Z80 implemented in VHDL on an FPGA • Memory — 1 MB • Os — MSX-DOS / MSX BASIC • Illustration — A 1chipMSX displayed with power adapter, instruction manual, and cardboard packaging.

The ESE MSX System 3 is designed by ESE Artists' Factory and distributed as 1chipMSX by D4 Enterprise and was supposed to be distributed outside Japan by Bazix. However, due to RoHS regulations in Europe, it was claimed it could not be distributed to Europe in its original form and the European market had to wait for an adapted version which would be produced through Bazix and distributed to Europe by Bazix. However, no violation of RoHS has ever been proven, with all identifiable components of the PCB and power supply being RoHS-compliant. Bazix stopped being the representative of MSX Association and thus did not bring the 1chipMSX to the Western market. In the end, MSX Association was dissolved due to a dispute with other parties involved, resulting in a shift of all intellectual property rights concerning MSX to MSX Licensing Corporation. Bazix also dissolved because this dispute made an end to their efforts and ambitions to bring the 1chipMSX to the Western market (along with other projects that were also dependent on the Japanese partners).
