PC-SPRINT contains step-by-step directions on how to accomplish a low
cost ($25 - $50) speed up for the IBM PC/AT/XT.  It can achieve
processor performance increases of up to 2 times normal, does not use
an expansion slot, doesn't make any permanent changes to the computer
and maintains software compatibility without restrictions.  Also, it
adds a true hardware reset - no more ``keyboard lockup.'' NOTE: This
package makes extensive use of printer graphics.  It is intended to be
printed on EPSON compatible printers only since most files contain
embedded EPSON control codes.  The DOS ``PRINT'' command cannot be used
because of this - all printable files must use COPY <filenmae> PRN
instead.  The batch file PCSPRINT.BAT will copy all relevant files for
you.

System Requirements:  128K, one disk drive and monochome/graphics
display, Epson-compatible printer recommended.

How to Start:  Enter TYPE 1STREAD.ME or TYPE PCSPRINT.DOC and press
<ENTER> for program documentation and printing instructions.

Program Description:  PCSPRINT is directions for a low cost ($25 - $50) speed
up for the IBM PC/AT/XT that you can build yourself.  It can achieve processor
performance increases of up to 2 times normal, does not use an expansion slot,
doesn't make any permanent changes to the computer and maintains software
compatibility without restrictions.  Also, it adds a true hardware reset - no
more "keyboard lockup".  Includes instructions, schematics, part placement
diagrams, and precision artwork from which a printed circuit board can be made.
It runs the processor at a higher clock rate to speed up the processing.
