Hello dear hackers and all about
chie. Those who live in the city of Yekaterinburg-
ge, and in general in the Sverdlovsk region and
heard about this computer, maybe this
Don't read this section.
For those who have heard about this computer
only from ZX-review magazines, I recommend ee
read.
And here we will talk about the great computer -
re Quorum 256. And I'm not afraid to put
it is on a par with such well-known developments
boots like Pentagon 128 and Scorpio ZS
256, but not lower.
The computer configuration is designed
as if especially for professional
nal hacker-cracker:
Hardware configuration:
- 256 kilobytes of RAM, expandable
rhenium up to 512 and 1024.
- 64 kilobytes of ROM
- SR/M Turbo 3.4T loader (about thisspeech
will be lower)
- Two ROM modes - 48 with extensive system
my menu and 128 is standard.
- Standard TR-DOS 5.04T;
- FFh screen attributes port;
- Port 0 - system port;
- Port CP/M 8OFDh
- Centronix printer controller with support
holding in 128 BASIC mode.
- Kempston controller;
- Possibility of connecting Kemp-mouse;
- Music coprocessor AY-8910(12)
- Non-maskable interrupts;
- Extended keyboard;
- System bus;
- Ability to connect C-DOS and Hayes
- No Magic Button.
But the last point cannot be attributed to non-
the advantages of this computer. Now I tell you
I’ll tell you about the CP/M 3.4T system and that’s it for you
gradually clear up.
This system flies at the same speed
as fast as TR-DOS, 128 kilobyte files
The files load in 40-50 seconds. System
works with standard Spekovsky resolution
by sewing a screen 256x192x8 Colors, using
The top screen is removed and installed immediately
RAMDISK C: with a size of 192 kilobytes.
The system prompt has been modified to make it convenient
it was to work with user areas
How about directories on a pussy:A:D>
where D is the name of the user's area. System
MA works with standard CP/M floppy disk
mi size 800 kilobytes.
This system has a special design
Norton Commander v.2.3. which is
is a complete analogue of the Pisish shell.
But, along with all the teams, she (beginning
(from version 2.0) also allows
deal with USERS as with directories. About
The tray also works with discs in the format
MS-DOS is exactly the same as with SIPEM
disks.
Hacker Evg/Stall developed a debugger
STD 2.xx, which is loaded into the top
part of the memory (additional RAM with address-
above 128 kilobytes) and is called
by clicking on NMI. The interface is very
similar to UKV emulator on IBM. Its possible
details:
- Work in CP/M format with Snapshots
type .SPC (Quorum Snapshot), Z80 - 48k,
Z80 - 128k - write read.
- Working with screenshots .PIC, .SCR (so-
same write/read)
- Working with object pieces of memory
(g/s)
- Program tracing (inincluding with
TR-DOS);
- Search for parts of text using a mask;
- Calculator;
- Disk explorer (get ready);
- Detailed Help;
- working with registers, etc.
- And most importantly, he understands the undocumented
bathroom commands (!)
Just a thrill for a hacker.
The main thing now is that there is no protection from Magic
Button will not help ;))))))). For example, you
load `Black Raven` and call
this shell by NMI. Write down the contents
my memory to disk in Z80 format and so on
ed. Then you can at least trace it
basically, do whatever you want.
By the way, I'm here with the help of this system
Binary traced along and across
Love, and tore the flashlight and plasma out of her,
Pravd` works slightly incorrectly.
By the way, the “lantern” was invented by our
by the native specers - the group `Allience`.
There is also a system in SR/M
Gamma-dos. It was made in the form of the usual do-
sa, has all the same functions, only working
melts not with .som files, but with .spc.
Zx-windows works just under it.
Well, that’s it, I scraped together a little, but who
worked for Quorum will not change seats
one other computer besides the Amiga.Let's give the floor to Sokol/Infotek

Today we will talk (and then maybe
ok, let's get it done :) about computers `Quo-
room-256`. The fact is that many people are confused
messages from happy programs about availability
128Kb of RAM, whereas SR/M uses
25bKb. In general, the feature for
tyrdos-256.
This feature is used for addressing
upper memory port #7FFD, more precisely the sixth
bit of this port. It may be crooked, but
but very simple. It turns out something like
de Pentagon-256.
Well, now to the soldering iron!
First of all, you need to find it on the MV
mikrukha LI1, which is located in the right
top of the board ina row of five micro-
Rukh, two (four) left ones of which "bu-
terbrods". Simply put, it follows from the right
count the fourth from the upper corner
chip to the left.
After this, solder the drawing below

Jumper 1 position corresponds to
128Kb, and, accordingly, position 2 -
25bKb of RAM. Well that's it, now Oberon
will swear about 25bKb of RAM and zag-
beat them head over heels.
Yes, if anyone is interested in
Why do you need a jumper, I answer - in 256 mode
not all programs that came before will work,
because some coders graduate to senior level
bits of all kinds of garbage, which leads to pe-
initial circumstances.
For this I ask you to take your leave (s)me, 1998.
