Now, where these days would you get a parallel port to plug it into?




I seem to recall that the USB ones don't work for this kind of thing. From my teenage memories, you could bit-twiddle by writing to a memory address. I presume the USB ones use a UART that doesn't allow direct memory access, or precise timing, or something.

The one linked in the parent is a PCI card, so this might not apply.


I still have a few computers from the 90s.

One of them is running openbsd and I think it might be fun to write a driver for it actually. I see OpenMSX also support covox.


even lots of modern motherboards still have serial and parallel port headers.
