Many people asked me for the PCB layout files. I have decided to stop offering the MyCPU kits and
instead interested people can now order the boards at their local PCB store. You can now
download the archive with all PCB files.

The MyCPU won the third prize at the Vintage Computer Festival Europe
in Munich. Thanks to all who have voted for us. Here are two articels
kiberpipa and
demonews
about the VCFe 9.0. Please see also these
pictures.

New software package released (EPROM release 1.11, Kernel 2.13).
The filesystem was very improved in speed, and the TCP/IP-Stack was updated to uIP 1.0.
The HTTP webserver has reached a stable state, thus the MyCPU can now be used
as productive webserver via a SLIP connection.
See a demonstration.

The MyCPU
got the first prize
at the Vintage Computer Festival Europe 8.0
|
 The MyCPU is a "Central Processing Unit" that is completely built
with discrete logic gates. Over the years the project has grown, and now the
MyCPU is the heart of a real Personal Computer. The computer has the following
capabilities and features:
- 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.

 MyCPU es una
"Unidad Central de Proceso" que ha sido construida
completamente a partir de compuertas lógicas discretas. A través de los
años el proyecto ha crecido, y hoy MyCPU es el corazón de una PC real. El
ordenador tiene las siguientes características:
- Esta construida a partir de circuitos integrados de la serie 74HCxxx.
No hay otros componentes integrados (a excepción de EPROMs, RAMs y UARTs).
- El sistema corre hasta 8 MHz.
- Hardware disponible: CPU de 8 MHz ("MyCPU"), 1.03 MB de RAM y 128 KB de
ROM, controlador de Interrupciones, Multi E/S con dos puertos seriales, un
paralelo, LCD e interfaz PS/2 para teclado, controladora IDE para cuatro
discos duros y una tarjeta gráfica VGA.
- Software disponible: Sistema operativo tipo DOS, juegos, herramientas de
disco, herramientas de programación, pila TCP/IP, servidor web.
- El ordenador puede programarse en BASIC, Assembler y C. El interprete
BASIC está integrado en el sistema operativo, y el Assembler es un
ejecutable que se carga desde el disco y traduce las instrucciones al
código binario de MyCPU. C es un crosscompiler que ejecuta en un host,
bajo Windows o Linux.
- El sistema operativo de tiempo real "pico]OS"
ha sido portado a MyCPU.
Las aplicaciones para pico]OS
deben ser escritas en C. Es un buen punto de arranque para estudiantes.
- El proyecto es completamente open source. Por favor contácteme si no
entiende alguno de los esquemas, software o descripciones.
