Hi Georg,
From the VirtualT Disassembler of T200:
; ======================================================
; LCD char generator shape table (20H-7FH)
; ======================================================
9063H DB 00H,00H,00H,00H,00H,00H,00H,00H
So the starting address would be 36963. But since John declared all
variables as INT in line 5 for improved execution speed, the number must
be represented as negative by subtracting 65536, so the address would be
-28573.
HOWEVER!!!! The T200 LCD works differently than the M100 display. For
the M100, each byte in the raster character data ROM table represents a
COLUMN of 8 LCD pixels. But for T200, the LCD bytes represent ROWS, not
columns, where the least significant bit of each byte is the left-most
pixel of a 6-pixel wide character, and there are 8 bytes for ALL characters.
So the program would need some updates to work with T200. I have made
those updates and also added code to display 10 characters at a time on
the larger T200 display:
5 DEFINTA-Z:C$(0)=CHR$(255):C$(1)=CHR$(239)
10 B=-28573:D=32:W=5:H=0:O=0
15 CLS
20 FORX=1TO10:FORJ=1TO8
25 P=(J-1)*40+O+H:PRINT@P,CHR$(47+J);
30 C=PEEK(B)
35 B=B+1
40 FORI=1TOW
50 L=CAND1:C=C\2
60 PRINT@P+I,C$(L);
70 NEXTI,J:O=O+8:D=D+1:IFD=128THENW=6
75 IFD=256THENEND
80 IFX=5THENH=40*8:O=0
85 NEXTX:H=0:O=0
90 I$=INKEY$:IFI$=""THEN90
95 BEEP:GOTO15

Hello together,
how to modify the program to run it on T200 using the bigger display?
Address of raster data?
