Who could share with me the magic incantation for obtaining 640 by 400 graphics from C/assembler for the AT&T PC6300? That is, if using int10h with ah=0, what should al be set to? And can the bios "write dot" int10h,ah=0ch function then be used? Or what is "the best" way to perform 640 by 400 mode line drawing? Is there a good book/manual on the level of Duncan's Advanced MSDOS that "knows about" the PC6300? Thanks in advance: if replies are emailed rather than posted I'll summarize and post if something of general interest results. ...!uwvax!marque!doug doug@mu.edu

The magic number you want is al=40h. For a good time try al=48h. The "write dot" function can then be used. > Is there a good book/manual on the level of Duncan's Advanced MSDOS > that "knows about" the PC6300? If you are willing to spend $65.00 you can order the system programmers guide from AT&T. Thats where I got this info. Just call 1-800-432-6600 and ask for order code 909-802-200IS. -- Peter Fales UUCP: ...ihnp4!ihlpe!psfales work: (312) 979-7784 AT&T Information Systems, IW 1Z-243 1100 E. Warrenville Rd., IL 60566
