                    ABOUT GMX

 Our company is constantly engaged in research and development 
aimed at empowering computer Skorpion (and, where possible, 
then the entire family of Spectrum compatible computers), and 
elimination of those shortcomings, because that is heard 
criticism from users, though mostly to other Computers 
(PENTAGON, PROFI). Time flies very fast, and life sets new 
challenges for our good old Spectrum'y.  First of all we are 
talking about improving the image characteristics computers, 
speed, memory size. On the other hand, because various reasons, 
today we release the majority of computers sold with the 
controller Kempston-mouse and keyboard as IBM they are easy to 
use, but not to ordinary tomuzhe ZX Spectrum keyboard is no 
longer available. Many bought and HDD (SMUC). Therefore, the 
end of 1997 will be the emergence of new Boards Scorpion, with 
the working title Scorpion-2000 (it's not mania greatness, and 
Why to choose this name will become clear enumeration of the 
technical characteristics). On this board will be already 
ustonovleny those controllers, which today have become popular 
and under who have already written a lot of software. This 
Controller IBM keyboard and mouse IBM, working on the interface 
Kempston-mouse, and most importantly, the controller HDD + IBM 
slot. By my own experience I can say that anyone who has worked 
with our HDD in TR-DOS, but about IS DOS and say nothing, 
usually neglect the fact that the computer ustonovlen still 
drive and remembers it only when it is necessary to rewrite the 
program from someone or for someone else. Ustonovka these 
ustroistv on the main board will free up space on the system 
connector for connecting new devices, HardWare, as already 
commercially available, for example, General Sound, and planned 
for release. But most importantly the cost of such fees will be 
much lower than today are all these devices, if you buy them 
otdelno.Pri The technical board that will be much higher and 
more will conform segodnyashnigo day.  Namely:



  1. RAM from 256KB to 2048kBayt (as 30pit Simm modules)

  2. Volume ROM 512 (IC 27040)

  3. Graphics: 1-Standard ZX Spectrum

                   2-640 * 200, 16 colors, aporatny scroller on

                     vertically, to accelerate the work in the 
text 

                     modes.

  4. Clock Speed ​​3.5 / 7 MHz switching both hardware

                     and software.

  5. Additional features (most interesting)

                   1. Ability to turn off all the extra

                   ports and the computer into rezhym standard
                   Nogo ZX Spectrum. When you disable the 
ports, so                    also included and the standard 
ROM. Same as 

                   but it also fully simulates the time
                   eters scans and Interrupt

                   Computer Pentagon, as the main component
                   puter, ispolzyemogo demo builders.

                   2. Since the circuitry board is made to

                   modern technical level with the use of
                   Niemi programmable logic arrays (PLA)

                   company Altera, and the scheme itself is 
"stored" in the system                    dark ROM, it becomes 
possible to measure                    nyat circuit computer, 
and a cardinal                    functionally, by simply 
replacing the ROM, or C / O                    lyucheniem banks 
ROM. The latter makes it possible                    sequence 
on a single board to have several variants                    
Comrade schemes computers that differ for example 

                   variantomi different frequency sweeps-one

                   for conventional TV and CGA monitors, other
                   Assuming for a VGA or EGA monitors. Golf 
question                    polishing of different ideas are 
more than enough.
