The Mensch Computer

The Mensch Computer

The Joy of Programming is Back!


The Mensch Computer is a reference design using WDC chips. We provide a FREE, digital form of the W65C265 Develop Board in our PCB Design Kits. For the individual who loves the legacy of the 65xx technology line of products this system displays some of the numerous possibilities of the technology. To program this marvel means to program without limitations. There is no operating system but instead firmware allows quick access to memory and registers, and internal working reference libraries show how to program the hardware. Call the internal functions, or program your own. Use the ROM monitor to jump to your applications or use a timer to create a multitasking operating system. With the Mensch Computer, you′re the boss.


The Mensch Computer is a solid state computer that was never designed to compete in the PC market. It's not a PDA, calculator, home controller or personal organizer, but it could be any of these things. It was designed to provide simplicity without complexity allowing users to evolve it into their own creation. Many people put a lot of thought and many years into the design to provide a head start for many projects. There are several assembly language library routines built into firmware and a ROM monitor allowing the ease of programming any of the included devices including graphics, sound, game controllers, communication to a PC, Printer or Modem or other solid state devices. The ROM monitor provides an easy interface menu for checking registers and modifying data in memory. All software listings, schematics and documentation are included.

The Mensch Computer is a popularized project to develop rapid prototyping of consumer electronics devices. For the first time, it is being offered for sale in limited quantities. The Mensch Computer has unlimited potential and has been used for the design of messaging systems, personal digital assistants (PDA), portable computers, communication devices and video game systems to name a few. This limited package includes the complete reference design, the Mensch Computer with keyboard and display, complete documentation and everything you need to excel with 65xx technology. Additional accessories are available to suit your needs.

Plenty of IO

The Mensch Computer has built in software to drive all of its IO, includes complete documentation and boots immediately after power up. Configuration options let you choose between programming from the built in operating system or you can develop your own, using the built in system as a guide. You can leave it running all the time because of the low power 65xx technology inside, or take it with you using the internal rechargeable battery.
