MyCPU - Self built PC

More tech-heavy stuff for the Mouse of Tech!

https://www.mycpu.eu/
A "Homebrew" computer!

Specs from the site
  • All is build with 74HCxxx circuits. No higher integrated parts are use (except the EPROMs, RAMs and UARTs).
  • The system runs with up to 8 MHz
  • available hardware: 8 Bit CPU at 8 MHz (the "MyCPU"), 1.03 MB RAM / 128 KB ROM, Interrupt Controller, Multi-I/O with 2 serial ports, 1 printer port, LCD and PS/2-Keyboard interface, IDE-Controller for 4 harddisks, VGA graphic card.
  • available software: DOS-like operating system, games, disk tools, programming tools, TCP/IP-stack, web server
  • The computer can be programmed in basic, assembler and "C". The basic-interpreter is integrated into the operating system, and the assembler is an executable that is loaded from disk and translates the assembly syntax into binary code on the MyCPU. The C-Compiler is a cross-compiler that runs on a Windows or Linux based host system.
  • The realtime operating system "pico]OS" has been ported to the MyCPU. Applications for pico]OS can be written in "C". This is a good starting point for education purpose.
  • The project is totally open source. Please contact me if you are missing something like schematics, software or descriptions.

 		I've been interested in these sorts of things for a while, and I'd love to design my own CPU sometime. I just don't have the resources.

 		Fantastic idea, Jay!
yes, I have to admit and I confess.

hmmmmmm.....and for the hard drive
how about a removable flash drive?
a few USB ports and the usual PS2 keyboard port
and one for the mouse.
a slot to read SD or MMC cards.
perhaps a slot for a external card reader.
8 in one, maybe.

And 3 things by all means!!

(1)detail your progress with more posts and blogs.
And some demo codes and programs.
And a few videos perhaps.

(2)talk and share with Andre Lamothe.
Perhaps an exchange of information and ideas.
And also a business partnership in the making??

(3with a few prototypes built and the architecture
and design finalized...choose one to custom build
for others.
I'll definitely interested in buying one.

You never know....

Jays Plug n Play.
Plug into a tv or computer monitor.
Play some dedicated games built-in.
Also, utilizing the built-n Basic, beginners can learn how to program. Especially game programming. Learn how to make games and have fun too.
When you are ready, move onto the more advanced languages of C and the bare bones of assembly language. You will
have more power and control over both the computer and
your games and programs too.

 		Yeah very cool project... Way above my own standards in electronics.
