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?
Compared to a new modern version of compiler (got to be £1500 I should think) a laptop (£350) is inexpensive. My current laptop is at least 8 years old, has limited memory and is slow.
