Alles anzeigenDrawing works, I used my DB HPGL Reader and changed "!LINE x1,y1 to x2,y2" to "SYS 59650,SL,x1,y1,x2,y2" and here we go:
Only the inverted screen at startup and basic 4 incompatibility remains.
AND another sad story: HR40 3022/4022 screendump is a loadable program! But we do not have it, from what I could see.
So no Hardcopys on the good old printers.
Looks good, I tried to find the screen dump code but nothing exists …. Sadly
