The Dumb Mouse is easy to build and it should not be too big of a problem to get the parts. If you build it yourself, it will cost about 25 guilders. If interest is high enough, a few kits will be made available some time later at a slightly higher price. We will then publish details on this page. Technical Specifications Serial port used for communications.
Power is supplied from the serial port or externally.
Vpp can be provided if necessary. 3.58 MHz internal clock, external or software clocking possible. Card reset can be active high or low. The Dumb Mouse is very easy to build for somebody who has ever hand wired a circuit. It is virtually impossible to do any damage to any of the components, the serial port or the chipcard.
