The objective of my web site is to foster tinkering. In my mind, this is the way people learn best.
Please note that proceeds from sales are used to buy additional stock, but more importantly, to buy equipment for development of the material on this web site and to pay students to develop material. Sadly, much of the web has become nothing more than a shopping cart with no development overhead. Please consider buying from vendors who not only sell, but also are striving to advance the craft.
My only advertising is word of mouth.
Please note that I am not in a position to do consulting.

PC Parallel Port
Note that these books were developed prior to the popularity of Windows and one could actually
run DOS and there was only one type of parallel port (now termed SPP). All routines were written
using Borland's TurboC Version 2.0 for DOS and I still use this old compiler in teaching as it is simple,
has a good debugger and will run on any PC. This is now available for free download at . Click on "Museum".
I have no plans to update these books for Windows.
Although the platform, a PC running DOS with a Stnadard Parallel Port, may not be as practical as it once was,
these books offer a wealth of information in interfacing with the real world. Indeed, they were written for a Parallel
Port, but one might argue that a port is a port, whether it be a 8051, 68HC11, PIC, BX24 or Basic Stamp.
Para Port Proto Cable. This includes a 3 foot flex cable terminated on one end with a DB-25 male connector to interface with your printer port connector and terminated on the other end with a 26-pin female IDS header. Also includes a 26 pin male header with wirewrap terminals. This allows you to interface the parallel port with a solderless breadboard. $11.00.
Wire Bundle - 22 AWG solid, tinned. Includes three feet each of four colors; red and black and
one light color (yellow or white) and one dark color (green or blue). This wire is ideal for solderless breadboards.
Solid copper tends to break leaving a breadboard hole plugged. (Note this is about 3 feet each.
In fact, it is measured as 4-1/2 wraps around my hand which has proven to be pretty close.)
Note that this is included with most of our kits. $0.95.
