Environmental: 0-70° C, wider ranges available.  No heatsinks or derating required.

DOS Stamp™ Compatibility return to top
The DOS Stamp™ is 100% instruction set compatible with the 8086, with extensions for enhanced performance. However, the DOS Stamp™ interrupt, timer, DMA, and UART peripherals are not software compatible with the 8259, 8253, 8237, and 8250 used in the PC. This means the DOS Stamp™ will not work with programs which use these peripherals.  Example programs are included with the DOS Stamp™ Starter Kit which show how to work with the DOS Stamp™ peripherals.  Call our engineering department to discuss your concerns or direct an e-mail to

DOS Stamp™ Software Development return to top
Developing your embedded application software is as easy as programming a PC. With the DOS Stamp™, you can use any compiled language which has I/O input and output functions and produces a stand-alone EXE.
The DOS Stamp™ is supplied with a C library which contains example programs and functions to operate the I/O hardware and speed your application development.
