What's Not In This Kit - David Griffith P112 Assembly And Operation Manual

One set of electronic components
All the hard work of finding these components at good prices has already
been done for you.
One 3.5" floppy disk
This is a ZSDOS boot disk created by Terry Gulczynski specifically for
this new run of P112 boards. The boot disk supplied by David Brooks
with the first run of P112 boards will still work, but is discouraged.
One copy of the Walnut Creek CP/M CDROM
This CD dated November 1994 contains assorted utilities, games, system
software, source code, and other things for computers running CP/M or
similar operating systems. It has long been out of print and Walnut Creek
has said that no permission is needed to reproduce it.
One documentation CDROM
This CD contains the new P112 documentation (which you are now read-
ing) and lots of other goodies like more utilities, operating systems, lan-
guages, and so on. A lot of stuff gathered by Rlee Peters is also included.
This CD is not documented in this manual.

What's not in this kit?

This kit doesn't include things that can be found at a typical consumer elec-
tronics parts shop. Other things you might want to complete this project can
be easily found on auction websites like Ebay. You might also have much of
these things already.
Soldering equipment All of these soldering items can be found at Radio
Shack (http://www.radioshack.com/).
A soldering iron drawing 15 to 30 watts is plenty powerful for this job.
Don't go any higher or else you'll risk damage to the board and/or compo-
nents. Make sure you have a narrow tip. One of those cylindrical tips that
you sharpen to a point with a file will work, but will be very frustrating
to use when mounting the expansion connector.
Plain old 60/40 solder of .032" or .064" (.6mm to 1.2mm) is good. If you
prefer 63/37, that's good too. Make sure you get rosin-core solder. Acid
core solder will ruin electronics. A solder of 96% tin and 4% silver is a
good choice of lead-free solder, but is more expensive. Two ounces (about
50 grams) of solder will be plenty.
It may be necessary to flux the board. I needed it. Others have reported
that it's not necessary. You'll know if you need it if molten solder will
not wet the connection you're trying to solder. The type of flux is not
