This page only contains updated information specific to rev 2 pc board. For general description of Tiny68K, please refer to this page .

Tiny68K is a high-performance yet low-cost single board computer based on the Motorola 68000. Revision 2 of Tiny68K has the following changes:

The Compact Flash interface of rev 1 is marginal. It may not work with faster CF drives due to ground noises generated by faster CF drives. Rev 2 design added isolation resistors to the data line, RC circuitry to the nIORD control line, and pull up resistors to the upper half of the 16-bit data line

A 'warm boot' button is added that will generate a non-maskable interrupt to the 68000 when pressed.

Add a real-time clock based on DS1302 that is backed up with a super capacitor.

Figure below shows an assembled rev 2 Tiny68K with annotations showing the changes from rev1 design.
