             TR-DOS 5.043v1



   VfNG / NEW


   We have already talked about the problems with Brest
DOS. For those who have not read previous editions of Echo, I 
repeat: the controller drives the production of local concern 
(BEMK) has a port other than the corporate controller. This was 
due to the fact that time when the BEMK began production of the 
disk interface, we have not yet smelled any TR-DOS'ami, and if 
started smell slightly, then no one could say that the TR-DOS 
will be the future standard. Therefore, the basis of disk 
interface was derived system CP / M, which, it must recognize, 
much steeper than wretched TR-DOS.



   But some time later, for some reason
TR is caught on ... And the project BEMK in support of CP / M 
flew into ... Well, wherever in the Union somehow always flew 
good projects. 


   By the time the expansion of the TR-DOS on
Brest Market and Belorus in general,
BEMK'ovskih controllers fired the sea. A TR-DOS and settle 
user'y groaned. K Fortunately, the interface BEMK had excellent 
ability: a downloadable ROM. Therefore, in order to satisfy 
users, was made attempt to adapt the TR-DOS 5.01 under the 
controller ports BEMK. More or less succeeded. Then b Brest 
showed up and 5.04T adapted as well. About 100% compatibility

to dream and do not have to, but life has become
possible. Moreover, in an adapted DOS was added a few nice 
features. 


   In 1997, tried a little pomuchat adapted version I, VfNG. 
Torment him until pulp and work was about 90% had not 
previously running programs. In addition, the my version of 
some work program, not working because of the separate fields 
of memory for branded controllers. I also added a couple of new 
features.

   Well, finally worth it to talk about
ports used in the controller BEMK:

008h = 01fh firm (the status / command);

028h = 03fh firm (track);

048h = 05fh firm (sector);

068h = 07fh brand (data);

009h: and here the main difference. Only
for recording and has the following significant bits:

       0: 1 = double density;

       1: 1 = include a motor drive

          0 = vyklyuait;

       2: 1 = side 0, 0 = side 1;

       3: 0 = drive A, 1 = drive B.
