Hello!
I have a customer that is asking if I can flash some very old microcontrollers.
They have provided me with their .HEX file.
The Part is an old 80C51 family P87C52UBPN, Philips semiconductor before NXP.
I think flash magic is the software tool to use, but I can't seem to find information on connecting the micro to a PC COM port.
Any help or suggestions are much appreciated!
Thanks in advance for your time!
