Up Work Sorpa - The indicator for signaling the driver drive. Toggle switch to switch drives.

         [Up Work to the scorpion]



 Scorpion yavlyaetsya perhaps the most popular 
Spectrum-compatible PC. And users "Scorpio" constantly invent 
all sorts of "navaroty for their favorites. Most often, these 
improvements relevant only for Scorpion'a, so we

and decided to open a special Rubik.


   In today's issue, I suggest to you
the attention of several interesting and very
utility improvements for the SCORPION'a.

1. Indicator for signaling drive drive. Really want to clean
"Fun" if you just want any updates. Some programs
work only with the drive 'A', and if you
ran the program with 'B', then the indicator
this case, even very useful. All of this
Theme made only ruleznosti;).

  I used the indicator mark: HP 5082,
but can any other. Likewise, if desired
You can twist and LEDs. The yellow
board element D65 - 555TM9, and on the green
like the D67, but in any case worth mikruha
under the VG93. A further look at the figure.

2. Well, this revision will help all those
who have two floppy drives, and those who are tired
each time the user drives from TR-DOS, pressing the button. And 
as for some programs: PRO TRACKER, DIGITAL STUDIO, and many 
others, where only DRIVE: A, is simply irreplaceable. Toggle 
switch can be even during loading, or write to the disk.


  Track connector drive, leading to
pin 10 - DS0 and 12 - DS1, are cut in places that are marked 
with a cross in the figure, and in accordance with the scheme 
is going to this design. 


  In one position toggle switch drives work like this:



  drive - A - the top drive



  drive - B - lower drive


In other cases:



  drive - B - top drive



  drive - A - lower drive


that is reversed. For convenience,
You can do this: to handle directed
toggle switch (up or down), the drive and
will work as 'A'. Very handy:)

3. Well, finally I will say that if you suddenly
you sit on the modem type VICOMM or compatible, and you do not 
have very good quality reception, then the chip 561ln2, is that

responsible for receiving (D43 to zh.pl.), we must
top okuratno impose more precisely the
same and, as practice shows, there comes
marked improvement. Go to 2400 grab.

  Currently, there are a few zadumok that later I hope you
present. ;)
