The Turbografx 16 (or Turbografx PC-Engine in Japan) has the most amazing fucking expansion port I've ever seen. Every bus is exposed, plus sound out and IN (unused by anything ever made for the thing), composite out (not included on the console itself, but 3rd-party addons allowed it), VGA out (!!!) and CPU HALTING/CLOCK CONTROL were included over this fucking thing.
You can even power the system with 5v in through the expansion port and bypass the power switch with it.
Info and diagram:

Example:
To get composite out, send pin A22 out and ground the ground wire of the composite to any ground.
For VGA, it's a little more complex:
VGA1 to TG-A23, VGA2 to TG-B23, VGA3 to TG-C23, VGA9 to TG-A2, VGA13 (and VGA10 if you want compatibility with older displays) to TG-B11, VGA14 to TG-A10, VGA5-8 (and 10 if not hooked to TG-B11) to TG-C2
(VGA numbering from Wikipedia diagram)
this thing's fucking cool1 -
So our new hardware guy who is being managed by our lead embedded developer had the task of designing me an expansion board for my Linux board. The Linux board uses the 40 pin expansion like the raspberry, bananna and orange pi family and as you all know there are many different types of expansion boards for this.
I said at the start come to me and tell me what you want to connect to before deciding which pin you connect to so it is less work for me with Linux board configs and drivers.............
No no no we will sort it all... erm.....
So today they come ask me if they can use an SPI port for GPIO and I am like erm... why there is plenty of GPIO...
It turns out they have been designing the board based on the pin outs of an expansion board and not the actual connector of the Linux board.. I mean seriously WTF!1 -
What if people, life, humanity, the universe is just a cluster of CPUs running a giant Recurrent Neural Network algorithm? 🤔
-Sun and food == power source
-People == semiconductors
-Earth/a Galaxy == a single CPU
-Universe == a local grouping of nearby nodes, so far the ones we've discovered are dead or not what same data transport protocol/port as us
-Universal Expansion == the search algorithm
-Blackholes: sector failures
-Big Bang == God turns on his PC, starts the program
-Big Crunch == rm -rf4
