<b>Problems Byte</b> - Why do not some programs on the Spectrum-compatible computer

(C) VfNG / NEW


   With this article I hope to put an end to
baseless attacks on individuals
me in particular and the 'New' in general. The point
that a wide range of programs not working
at Brest version of Spectrum-compatible computer, and since 
most of the import programs carried out in Brest

namely us, it's no wonder that some
incompetent person trying to explain
Downtime of these products to our
intervention. In reality, much worse ...

;----------------------------------------;


   Program to 'byte' does not work mainly for three reasons:


   1) The machines 'byte-01', and others with
drive controller output BEMZ,
access ports to the drive are quite different from TR-DOS (the 
first BEMZ'ovsky controller appeared in Brest long before the 
first controller TR-DOS). Initially, the controller was focused 
on CP / M. Later, with the goal of compatibility with

TR-DOS, was written a downloadable ROM
capable of this same TR-DOS to emulate.
100% compatible, unfortunately, dobitsya
failed ... Therefore it is not running the whole
a lot of programs from boot loader through
# 3D13, such as UFO, ZX-FORMAT, etc ...
Turbo loader, normally running at all
we know the types of machines, and to 'byte' in
including those published in the first issue
Echo.


   2) 'Bayt' machine to speed a bit,
but still far behind the Spectrum brand. What does this mean? 
And it means that many programs, especially demuhi,

do not fit into a INT and terribly slow down or simply do not 
work. About the program under the PENTAGON, PROFI, etc. and say 
nothing. These programs include, for example, almost all 
ENLIGHT'ovskie work. Can not work for this reason and Magic 
Screen ... 


   3) 'byte' to the same as the corporate
Spectrum, a machine with separate fields of memory, ie 
different parts of the memory work at different speeds:



   48K:


   0000-3FFFh FAST

   4000-7FFFh SLOW

   8000-FFFFh FAST


   128K:


   Both ROM FAST

   4000-7FFFh SLOW

   8000-BFFFh FAST

   Pages 0,1,2,3 FAST

   Pages 4,5,6,7 SLOW


   Work with all types of data lying
in areas SLOW runs at 25% slower.
If in these areas to hang vector I, then
25% slow down the whole machine, including
including working with the drive. And this
means that neither read nor write will not work as expected. In 
addition to the 128K, I can not hang a vector in the region 
C000-FFFFh. For this reason (the vector I in the wrong

site) did not work prestizhevsky solitaire
did not go downloading Magic Screen, discharge into
Pro Tracker'ah, King's Bounty. Remember
once and for all:

 - While working with the drive I have
be equal to # 3F, because he does so DOS!
It's a standard!

 - In any demuhe vector I should stick
in # 8000 - # BF00! So you'll get
some compatibility with the firm Spectrum and zabugornye 
Spektrumisty will swear a lot less. 


   This point, incidentally, refers not only
'Bytes', but also all other Spectrum with
separate fields of memory.

   Consider, please, described herein
things. They are not difficult to comply with and benefit from
are solid.

   Actually, 'New' is now in the ground and
engaged in adapting non-business programs.
It takes about 70% of our working
time. The biggest trouble we
deliver TURBO LOADER'y FLASH, ZX-FORMAT, ZOOL00K. Already 
brought to mind the hundreds of things, no wonder, therefore, 
that has not done without some errors:



   PRO TRACKER 1.1: persists incorrect recording on the disc. 
Adapt will not be, because of outdated software.



   PRO TRACKER 2.1: Brest to walk with a slow version to disk. 
Those with Who is this version will overwrite the normal at any 
of the members of the 'New'. Generally, in Both PRO TRACKER'ah 
was originally incorrect synchronization, so that normal plowed 
only 'New'shnye version. 


   ICE CLIMBER: walking version bungle
FINAL CUT'om. Normal-all members
'New'.


   INSULT: adapted by just under
'Byte-01'.


   There are also several game with our
old intruhoy (February-March), there was
Booting from disk working properly
only to 'Byte-01'. It has long been a normal
version.


   All of these errors were committed during the period
'Youth' and more will not be admitted. In general, argue that 
not work a program to blame the people of

'New' can be used only if
indicated that we are in it tinkering. This is not
difficult to determine because All Hacker 'New'
have their own standard loader. Each of us has its own 
parameters Start and Length in the head BASIC:


VfNG ............................. 91, 65535
Max Kopein ........................ 250, 250
ADIA ............................. 64, 64000


   So if you have something not working
our fault, then do not cry, do not yell,
just call us and let us know where you are
is found. Replacing buggy versions of the normal done for free.

   Let's try to solve our
problems! Maybe in other cities have cars with some their 
difficulties? Write to us about them!
