To top it all off, some Chinese FPGA development boards complete with camera input, display output (including HDMI), a respectable amount of RAM, and an SD slot have become available for around $20 pre-shipping. These are perfect for implementing small CPU designs as found in older processors.

I occassionally will find a video where someone is using a GPU board to "simulate" (is that the right word?) a DOS machine. They are usually doing
it for gaming. I sometimes wonder if there are any with an actual RS232
serial port that could be used for some BBSing purpose.

I usually lose interest when I realize that I could just use an old
machine, if I don't mind it heating the room in the Summer, or don't mind
that I cannot use nfs networking to access my network shares on a DOS
machine.

As if all of that wasn't enough, the FujiNet also has running on that same microcontroller an emulated Z80 CPU running CP/M, which can be accessed from the Atari.

I was reading an article on osnews.com recently about CP/M and how the
owners have said it "and all its derivatives" are now free. The author was questioning whether that was restricted to just CP/M derivatives, or also things like DR-DOS, which apparently started out as a CP/M extension.

One thing I did not glean was whether or not their are also open source,
i.e. if they source is out in the wild or if it even still exists for some
of the projects.

Some of the derivatives and extensions could do things that other versions
of DOS that were out at the time could not do natively, like multitasking.
