				HI!

I have the following problem:

I want to create a unit in Turbo Pascal (7.0) that replaces the standard 
graph.tpu and supports more screen resolutions than the standard unit.
I am looking for an assembler sequence to do a REALLY FAST putpixel.
I have one for the 320x200x256 mode, but that doesn't work for the higher 
resolutions (especially 640x480x256). The only method I heard of is to call 
the interrupt, but that one is awfully slow...

Any suggestion is welcome, Thanks
(Please reply to my personal E-Mail adress, as I am not a regular news-reader.

				HALLO!

Ich habe folgendes Problem: Ich moechte eine TP-Unit schreiben, die die 
Standard-Unit graph.tpu ersetzt und mehr Grafikmodi ansprechen kann 
(>16 Farben).
Nun zum eigentlichen Problem: Ich finde keine schnelle Assembler-Sequenz fuer 
"putpixel". Die Variante mit dem Interrupt-Aufruf ist schrecklich langsam, und 
die direkte Speicher-Adressierung funktioniert nur unter 320x200x256...
(Assembler-Code waere nicht schlecht).
Rueckmeldungen jeglicher Art bitte nicht in die Newsgroup, sondern an meine 
E-Mail-Adresse. Danke im voraus, Klaus
