- Where did you hear that? I've done binary compares of the object code in
- TPU files and TURBO.EXE, and it's pretty clear that it contains the
- following units:
-
- DOS, DRIVERS, OVERLAY, SYSTEM, COLORSEL, STDDLG, DIALOGS, APP,
- MENUS, VIEWS, HISTLIST, MEMORY, OBJECTS
-
- If that's not using TV, what is it?
-
- If you're interested in more details on the compares I did, look for
- TP6MAP.ZIP or TP6MAP2.ZIP. I think at least the first is on garbo in
- /pc/turbopas; it gives the addresses of all the routines in the above
- units, to aid in patching the IDE. The second adds a map for the June 91
- release of the compiler.
-
- If you really think it's possible to patch TV to use a special video mode,
- I'd recommend getting a copy of the map I made. You might get away with
- just a few changes to the DRIVERS unit, or maybe it's not possible at all.
- I don't know. For some idea of what sort of difficulties to expect, look up
- the TVG package, that tricks TV into running in graphics mode.
