| Welcome to the English version of my build-it-yourself
microcomputer website.
With the navigation bars you can easily
visit every page on my website.
On this homepage you can find all sorts
of info about the microcomputer designs I have made with the help of CAD.
The designs are all single-sided PCB designs, so they can easily be etched
at home with your own PCB setup.
Most of the designs are based on the ZX80
and ZX81 home computers that were made by Sinclair Research, supervised
by Sir Clive Sinclair, back in the early nineteen eighties.
These computers will probably be more
well-known amongst readers who are somewhat older, since they were made
in the early eighties.
The ZX80 and ZX81 were amongst the first
really affordable home computers that used a television set as a means
of communication with the user.
The programming languages used on the
ZX80/81 were BASIC and ASSEMBLER, however it is even possible to use FORTH
and some other languages.
A few years ago, Wilf Rigter from Canada
has also made a 'ZX' design, the ZX97.
This is a completely new design that not
only uses better technology, but can even do several things the original
ZX81 can't.
Wilf provided the schematics for the ZX97
in ASCII, and I subsequently made the CAD ZX97 designs on this site with
some debugging assistance from him.
You can find some general information about
the projects and what you can do with the resulting computers in the Intro
section
Under Project groups there is a number
of pages in which there are several projects that you yourself can build
at home. That is the actual purpose of this website.
Of course, some soldering experience and
knowledge about electronic parts will be necessary. However this does not
mean that an electronics education is required!
