Since I am autistic, I have trouble understanding when exactly someone is
making fun of me or what tone they are using, especially trough text.
For the sake of friendliness I shall assume that you said all of that in good
spirit and were not condescending.

I knew about Ben Eater for many years, I am extremely interested in
microelectronics.. I am also interested in chemistry and creating your own
transistors and stuff - silicon, etc. ... but that stuff FOR NOW is
unimportant.
Did not know about James Sharman, though.

There was a dude whomst I forgot about; he created his own RISC-V CPU and
hardware around it - motherborad, even add-in PCI-like daughterboards for stuff
like VGA and keyboard support if I remember correctly.
That computer was a intelligent multi-story, stacked tower - great design,
keeps things separated, cool-looking and organized.

And if I were to create something usable, I shall write a super ultra-simple
guide on how to do it yourself - DIY - unlike best of best manual pages *cough*
*cough*.
So almost everyone could make such a thing at their own home, perhaps not the
FPGA itself (which I plan on preferring), but everything around it?

I am unsure of the complexity of working with FPGAs - software or hardware
wise.
I admit my lack of such, but not knowing has never before stopped me from
learning, and it shall not stop you.

Like said - we have a lot of existing CPU architectures and other designs, and
we can extract the best of the best from everything, and combine everything
into something just beautiful!





Okay, I browsed the James Sharman's YT channel, and just by reading the video
titles - I got extremely excited!
The moment I read "Storage (SD Card Support)...", I remembered that there
exist web-siteS that explain how you can add support to an >>FPGA<< from
storage stuff (SD, HDD, SSD), to networking, etc., which is more valuable than
fucking gold!

Holy shit if I don't archive their web-sites and all media they have, that
stuff cannot be allowed to stop existing!!


Since I extremely-extremely love problem solving - creating and debugging
hardware ought to be fun!
I cannot wait to spent 5 hours figuring out how I missed 1 resistor or whatever
:')


Anyways - assuming you were serious and nice to me - fuck genius ass or rather
geniuses fuck good ass?
