reader-reader - The printer driver for the Scorpion.

(C) Motov A. g.Usole-Siberian


   I would like to offer readers
your printer driver
"ZX-WORD 2.1" for the "Scorpion."
The fact that I have a printer
"CANNON BJ-30", which has
855 table instead of 866. Driver
recode characters in the issuance of
to the printer in accordance with 855
table. The program is very simple
and needs no comment.

   For normal operation you must change the contents of a cell 
with an address to 28,111 # E0 at # DF. The reason is described 
in N5 for 1994. Makarycheva VP Like

have noticed that I have the program works, and in the mode of 
128K. 


   Ed.: To assemble this
Driver MASM'e need instead of lines:
140.

          ORG # 5B00

insert a combination of lines:


          ORG # C000

          PHASE # 5B00
2

   With this approach, MASM will generate the object code in 
the address # C000, but really the program must be run from the 
address # 5B00. 

   This restriction is absent in all
TASM'a versions.
