MXSET Rev. 1.2 by Simon J. Ewins, Toronto, Ontario, Canada.
***********************************************************

This program will set/reset all of the major functions of the Epson MX-80
printer. The program uses Z80 Zilog mnemonics and calls are made to Richard
Conn's excellent SYSLIB.REL file. Microsoft's M80 macro assembler is needed
for assembly of this file as well as the SYSLIB file.

June 28, 1983.   Toronto, Ontario.
