The iPDS (Intel Personal Development System) was a portable system intended to support both hardware and software design and development for boards based on many different families of Intel microprocessors (8085 or 8088) or embedded microcontrollers (8031/8051/805X family).
The unit was powered by an Intel 8085. It contained one floppy disc drive and a 64 KB bubble memory chip that could be used as a boot disk if no floppy disc was inserted.
Through the InCircuit Emulator (ICE), the iPDS was used to physically emulate the microprocessor of a host development board. the ICE was plugged where the CPU would go and the programmer could use the console to bring up the ICE software and single step through the compiled code, set break points, modify run and test the software.
When the program was completed, using the iPDS editor and assembler an EPROM burner module was used to save the program into an EPROM chip.
Several optional modules could be obtained from Intel, depending on the type of emulated processor and Eprom chips to be programmed.
Mike Boyd adds:
You could add a second CPU to the system and both could run at the same time, you would toggle back and forth by pressing a key sequence.
