Implementation of WordStar on the Kaypro 4 for MX80 with
Graftrax. NB: This is NOT for the serial port, but for the
parallel port, system list device (LPT:).
HARDWARE INSTALLATION
The "dip switches" on the parallel board are as follows:
SW1-8 ON Comes up ON-LINE
SW1-7 ON Zeroes will be slashed
SW1-6 ON Buzzer on when paper fault occurs
SW1-5 OFF Emphasized print is NOT the default
SW1-4 OFF Italic print is NOT the default
SW1-3 OFF Paper fault sensor is ON.
SW1-2 OFF --not used--
SW1-1 OFF Compressed print is NOT the default
SW2-4 OFF 1 inch skip over perforation is NOT selected
SW2-3 OFF LF must be from host (the KAYPRO)
SW2-2 OFF --not used--
SW2-1 OFF --not used--
SPECIAL PRINTER INSTALLATION
under GP INSTALL Release 2.00
.............................
PRINTER NAME Epson MX80/100-Graftrax
INITIALIZATION 0dh
(empty)
OVERPRINTING Non-backspacing standard printer
BOLDFACING 3 overstrikes
PROTOCOL None
DRIVER System Standard List Device (LPT:)
RIBBON SELECTION 1b34h selects alternate ribbon (italics)
1b35h selects normal ribbon (no italics)
VERTICAL MOTION (this was set for non-graftrax printer
as released with WordStar. Maybe it's
unnecessary, or incorrect. I left it
alone, but I think it's wrong...)
HORIZONTAL MOTION (DITTO, as above...)
PRINT MODES 1b551h selects unidirectional printing
1b550h de-selects unidirectional printing
(NB: There is a GROSS error in the
Epson manual, so be sure to check the
Appendix B "decimal" and "hex" values to
be sure they AGREE arithmetically.
Contrary to Epson's manual,
85 decimal DOES NOT = 5F hex!!!)
PHANTOM CHARS. 20h (ASCII space) no phantom space
20h (ASCII) no phantom rubout
RETURN/LINEFEED 0d0ah is CR and LF
0ah is LF
(empty) half-linefeed not functional
0dh is no linefeed
USER-DEFINED
FUNCTIONS 0fh for ^PQ (function 1) is select
compressed mode (little characters)
12h for ^PW (function 2) is de-select
compressed mode (normal characters)
1b48h for ^PE (function 3)
cancel subcript mode (this is used
IN ADDITION to the ^PV and ^PT functions)
(empty) for ^PR (function 4)
CARRIAGE ROLL 1B530h lies to Wordstar that this is a 'roll
up a partial line'. Actually, this sets
superscript mode. NB:See function 3 above
which MUST be used to de-select superscript
mode, or else everything following will be
in superscripts.
1b531h lies to Wordstar as above, except
here we're selecting subscript mode. NB:It
also MUST be de-selected as above....
CHARACTER PITCH 1b571h selects double-width (big characters)
1b570h de-selects double-width
