I started with VHDL, and almost understand it, in the sense of the way the simulators use it, and how the Xilinx synthesis tools use it. I still get hung up every once in a while with code that does totally bizarre things, and just have to poke at it for a while until I get what I want. > > >>The m5i210 has been used before to run machines.

PCI parallel ports actually work better than the motherboard ones, at least on some systems. If the PCI goes away, the Mesa board won't work, either.
