Hardware - comparison of hard drive controllers: SMUC and IDE-HDD (iS-DOS).

       Hard drive controllers: SMUC and IDE-HDD (iS-DOS)


    First, let's take a closer look at both of these controllers.
SMUC from SCORPION.
 The software is flashed into the computer's ROM, that is, upon purchase
SMUC also needs to purchase a special ROM.
  Together with the controller (on one board) some
not entirely necessary devices, the software support of which is not pre-
designed by manufacturers, so few people support them. Ta-
This trend can be seen in almost all of the company’s developments.
 The IBM keyboard controller and KEMSTON MOUSE are together again. A
What if I don’t need any of this and will never need it? About
Comrade Zonov didn’t think about this. Further GMX again the same picture pa-
2 Mb and Turbo mode are very necessary, but everything else:
two graphic modes with higher resolution - this, in my opinion, is not
for us, with such speed.
  The controller can operate under the control of any known
OS today. Under TR-DOS, the hard drive is divided into subsections, in which
which can accommodate up to 50 pseudo TR-DOS disks. At the same time, everything
programs located on the hard drive must use the
Dart entry points into the system. For iS-DOS, the hard drive is also partitioned
divided into subsections, but already 10 M each. This is done for more
reliable operation of the hard drive. But restrictionsdo not overlap
only on the size of the subpartition, but also on the system itself, you cannot use
use a new version of the system, which is specially designed
for computers with a memory capacity of 256Kb and above (Chic). This version
the system actively uses the 8th jar, where the shadow itself is located
monitor, no monitor, no hard drive. Because of this, it is impossible to
children will use some programs and sit in the old one
a system not used by anyone, by the way iS-DOS supports up to 8
devices, that is, 80 Mi will be available to you. But don't think -
those that this is the limit - no, you can connect to various devices
cham different subsections, so you can use not only
80 M, and much more. Nothing to say about other systems.
I can’t say for sure, but the advertisement says that they are also supported.
IDE-HDD (iS-DOS) hard drive controller from Nemo.
 The name of the controller speaks for itself, that is, software
support is provided by the best OS.
  Together with the controller, nothing except a cable and instructions
supplied, and this greatly affects its price, a hundred
Ron reduction of course.
  As mentioned above, in order to work with a hard drive you need to
will achieve iS-DOS, but not the old one, but the new one, in which
innovations.
  1- for those who have a lot of programs for TR-DOS, it will not be superfluous
say that the new IS-DOS comes withprogram, co-
which creates TR-DOS disk images, and you can safely place them
to the hard drive.
  2- memory available to the programmer has been increased to 26 Kb.
  3- some useful programs, for example a zip archive unpacker
WWII and much more.
  This controller can be set to a device size of up to
16Mb, and the hard drive can be installed in any capacity.
Now you can compare these two controllers.
 1 The price, naturally, is lower for a controller for iS-DOS.
  2 SMUC has incomparably more opportunities, but it would be much more
it would be better if the shadow monitor was not in 8th, but in any
another jar.
  If you don’t have a lot of money, then it’s better to install on your computer
Computer hard drive controller for iS-DOS. It's much cheaper
especially since our group is actively working on creating
