This is purely a hobbyist endeavor, originally motivated
simply by the
Rev 0 board to use in my original Apple II. Also, the flakey
the existing motherboards that I have been using, has been a
significant motivating factor. Building a single PCB was not
economically sensible, so I initially built 6 with the lowest
could find. I only needed 2 boards, so decided to put
other hobbyist that might be interested in this project.
my delight, the initial lot of boards has been completely
has been a lot of fun and a challenge to try to find
best source for each component. This search has become an
interesting hobby unto itself for me.
If you are interested in building a rev 0 replica for
yourself, I would hope that you have some
previous kit building experience. If not, I would start with
smaller project, such as one of Vince Briel's Apple 1 replica kits.

- Building a computer is fun and rewarding.
- Original Apple rev 0 systems are rare (about 6000 made) and
to obtain. If you run across one at a bargain price, let
know, as I
have been looking for several years.
original low serial number Apple II lost it's rev 0 board
along the way.
- A replica rev 0 will be more
reliable than a typical 30
year old original.
- Early micro-computers are
great vehicles for learning about
the basics of computer technology.
- Unlike some
early micro-computers, a rev 0
Apple II is a completely functional computer. Back in
early 80's, after adding two Disk II, floppy disk drives,
mother was able to computerize her accounting business with my
rev. 0 Apple II.
- A rev 0 Apple is a great tool
for learning other aspects of
electronic design. An example is the shutter tester card
built using my Apple II, just a couple of years ago.
- Integer BASIC and Applesoft BASIC are languages that are
ideal for learning the basics of computer programming.
I launched a career in software engineering by learning
- Many, many programs are available
for the Apple II (most
are free to download from various web sites).
built your own computer, you will have bragging
rights around your neighborhood.
Many of these items can be obtained by locating
purchasing a relatively inexpensive Apple II plus computer.

are very inexpensive on ebay, in order to source these

Note about ongoing
changes to kits
- Due to the vast amount of time required to put together
kits, I currently only ship bare PCBs for Apple II rev 0 and
Mimeo reproductions. Most parts are available
from standard Unicorn Electronics (http://www.unicornelectronics.com)
stock. See this page for more information about what is needed to build a motherboard and where to get it.
