PARPORT:  PARALLEL PORT I/O FREEWARE  Includes:

SEEBITS:  DOS Fullscreen Control and Monitoring of Parallel Port Bits
-------   with large 'Bits' that can be seen across a classroom.

SeeBits uses a "Printer Port" (often called a "Parallel Port").
The port is "unscrambled" so that you have one 8-bit output port and
one 8-bit input port using adjacent pins of the printer port.

NAMEBITS and BITMACH:  State Machine programming environment that needs
---------------------  No Compiler to write programs that run from
                       bits on the Parallel Port.

NAMEBITS EXE   -- NAME the parallel port bits according to your use
                  of them
BITMACH  EXE   -- Define, run and debug machine sequences that make
                  decisions based on parallel port bits, timers,
                  counters etc. Control output bits.
                  Control program sequences and loops.
                  Save and load BitMachine programs

PARPORT support libraries in TURBO PASCAL:
------------------------------------------

PARPORT utilizes an IBM-compatible machines PRINTER PORT, often called
the PARALLEL PORT.  PARPORT 'fixes' the funny way the bits and ports
were designed, specifically to control a printer.  All you need to do
is think of your machine as having (1) An 8-bit OUTPUT port, with the
8 bits connected to pins 2 thru 9 on the connector, and (2) An 8-bit
INPUT port, with the 8 bits connected to pins 10 thru 17 on the
connector (Pins 18 thru 25 are GROUND).  You've probably heard of how
weird the parallel port is!  It's true, but this software fixes it by
moving the funny input bits around and inverting those that need it.

This level of software is for those who write their own programs in
Turbo Pascal (From Borland) and want to control the parallel port.  If
you're just starting out and don't want to write any software YET, use
SEEBITS.EXE

These routines have been developed over several years of use with
school kids, primarily in grades 5 to 8. The program that I put
together is referred to as "Bit & Bytes".  Sometimes kids get into a
longer-term project called "KidMachines" where they design and build
some funny computer-controlled machine.

...If you get this software and use it or have comments, PLEASE let me
know so I have some idea of how useful this is.  I KNOW there are some
deficiencies, especially editing in BITMACH.  But I want to hear what
you'd like...
