This article is from the newsnet system. It talks a little about NMIEN. Tidied by Dean Garraghty.¢-----------------------------------¢¢> So, anyone that good? (hehe..) I would try using a DLI (which I have a¢> LITTLE bit of experience with fiddling with), but I still need to figure¢> out how to shut it off before I change the pointers at 512 & 513 (it¢> usually just crashes!). I recall reading something about that.. I forget¢> where, and I don't think it went very deep in explaining. So...¢> Please respond ASAP!¢> Bill¢here it comes:¢¢You need the location NMIEN 54286 ($D40E) to disable the DLI simply set the bit nr. 7 to 0. The bit nr. 6 serves for the control of the VBLANK interrupt. The most simple way for doing it is to type POKE 54286,0. Then both the DLI and the VBI are off. When you want to turn the DLI on type POKE 54286,128. (VBI: POKE 54286,64 ; VBI & DLI : POKE 54286,192)¢¢Marek Tomczyk¢ E-mail: uj1g@ibm3090.rz.uni-karlsruhe.de¢¢
