I have a Leading Edge Model D (XT clone) which I am using for control
of laboratory experiments. It is fitted with a standard monochrome
monitor. My application programs are all written in MSC (5.0), which,
apparently, only supports true-blue IBM graphics modes. Does anyone
have experience with using MSC on a Leading Edge, who can tell me how
I can access the graphics screen? I presume that the graphics is
handled in BIOS -- how can I access these routines?
Thanks in advance,

They will be happy to send you a description of the interface if you call their tech support line (617 821 4300). Leading Edge's explanation of why this is not in- cluded in the regular literature is that the vast majority of people who buy their products are not 'technical' and don't want to program their machines. Or contact your dealer and he can get it for you but that will probably take longer. Using the graphics involves writing to certain locations in memory. The Phoenix BIOS used in your computer is a superset of the regular IBM BIOS, in that it *does* include features which allow GW-BASIC to use the Herc graphics but Leading Edge refuses to release any documentation on it and Phoenix insists that it's the licensee's job to provide support. --Peter Nelson
