I have an old version of the C51 compiler which needs a parallel port dongle to generate a compiled output (Compiler V5.0/uVision 1.13). Parallel ports are disappearing on laptops and also on desktops. What options do I have? Is there a USB to parallel adaptor that may work? Do I have to upgrade to a modern version of compiler, which is not economically viable in this current economic climate?
Someone, all those years ago, must have worked out that it was worth buying that Keil licence.
What's changed?
