All you know it's very easy to find some free examples of MSC-51 development boards with some basic components (MCU + MAX232 + SRAM + EPROM etc.) and there is no problem to find a monitor program working with such system.
But, I have never seen really free examples of In-Circuit Emulators. Is it taboo ??? Is it to complex to develope such system or is it too expensive ? I'm trying to create my own project (diploma work) - but I can't find any examples on the net. Who can explain this situation ?
