====== COMPUTERS  ======
INT

You can operate, manipulate, and hack into computer systems.
If you don’t have physical access to a computer system’s user
interface, you must use a hacking kit to access and manipulate
the system. 


Computers are set up to give one or more authorized users
“root access,” allowing them to access any information or
function of the computer as a standard action, with no need for
a Computers check. Systems can block off specific sections of a
computer and grant different users root access to those sections.

The base DC for many of the tasks of the Computers skill
is equal to Complexity*2 with additional tech based and interface based modifiers below.

DC:
^Modifier^DC^Notes^
|Computer complexity|2*complexity|Base modifier, round to full number|
|Interface, one of below||
|  Non display terminals|+7|like card decks and similar|
|  Non display keyboard terminals|+6|Like teletypes and similar|
|  keypad|+5|just a numeric keypad or similar|
|  mini keyboard|+4|typical early portable computers or phones with keyboards|
|  mini touch screen|+3|Like a typical smartphone|
|  touch screen|+2|Tablets and similar|
|  Keyboard|+1|Typical for early stationary computers|
|  Keyboard and mouse|+0|or keyboard and touch screen|
|  multi-monitor/wall screen setup|-1|with keyboard and mouse or large touch surface screen|
|  Virtual reality|-2|  |
|  Holographic display|-3|  |
|  Direct neural Interface|-4|Also if you have a computer brain|
|Interface timeline||How well developed it is compared to similar interfaces|
|  Prototype|+2|  |
|  Early|+1|  |
|  Normal|+0|  |
|  Late|-1|  |
|  Ultimate|-2|  |
|Interface quality||  |
|  Poor/cheap|+1|  |
|  Normal|+0|  |
|  Good|+1|  |


These DCs may be adjusted by the GM to reflect other circumstances.

Examples for the starting tech:
  * Both Organizer and OrganizerII: 12 Base DC for complexity. They have normal mini keyboard for +4 and thus a final modifier of 16. Thus you need skill 6 or higher to be able to use base functions "automatically" quickly(take 10)
  * Home comp I, 12 Base DC for complexity. They have Early keyboard for +2 and thus a final modifier of 14. Thus you need skill 4 or higher to be able to use base functions "automatically" quickly(take 10)

===== Access Unsecured System =====

You can use Computers to access an unsecured computer
system’s most basic functions. The DC to access the information
or functions of a public computer with no countermeasures or
limitations is generally equal to the base DC -2 for limited information systems like a public info display, the Base DC for more broad systems.

If you want you can attempt to access a system by taking 20 on the task, requiring 2 minutes. 
Secured computer systems, and secured sections of an unsecured system, can be accessed
by making a Computers check to hack a system.

You can also take 10 for access if you are familiar with same or similar systems in base time.


===== Create or Detect Forgery =====
You can use Computers to forge official electronic documents. This takes
1d4 minutes. The GM rolls the Computers check to create a
forgery in secret, so you’re not sure how good your forgery is.

This check is opposed by the Computers check of anyone who
examines the document to determine its authenticity.

The DCs for Computers checks to detect a forgery are based
on the type of forged document as well as other circumstances
determined by the GM, as shown in the table below.

CIRCUMSTANCE DC MODIFIER
|Document contradicts knowledge or orders| –2|
|Type of document is well known to examiner| –2|
|Type of document is unknown to examiner| +2|
|Examiner only casually reviews document| +2|
|Forger has a sample of a similar document| +8|

===== Destroy or Repair System or Module =====

You can use Computers to repair a computer system or module
that has been disabled, or destroy one that has been either
removed or disabled by spending 10*1d6 minutes working on the computer. 

The DC is based on the tier of the computer system. If you are repairing a disabled
module or system and you fail the check by 5 or more, you
accidentally destroy the module or system. You can’t take 10 or 20
on a Computers check to destroy or repair a computer system.

===== Detect Fake Shell =====

If you have access to a computer, but not root access, you may
actually only have access to a fake shell (a computer countermeasure
that grants access to fake files instead of real ones). If you succeed
at the check, you realize that you have accessed a fake shell. The
DC is based on the tier of the computer system.

===== Disable or Manipulate Module =====

A character with root access to a computer can disable or
manipulate a countermeasure or module as a standard action with
a DC 10 Computers check. If you have access (but not root access)
to a computer, you can attempt a Computers check to activate,
add, disable, or manipulate any countermeasure or module. If
you want to affect a countermeasure or module that is behind
a firewall, you must first hack the system (see below) to gain
access to it. Activating or disabling a countermeasure or module
generally takes a standard action. Adding or removing a module
generally takes 1 minute per DC from complexity and interface. All of these
tasks have a DC equal to the DC to hack the system. You cannot
take 10 or 20 on a Computers check to disable or manipulate a module.

===== Gain Root Access =====

If you have access to a computer, you can attempt to upgrade
your authorization to gain root access. This works similar to
hacking the same computer, but the DC is 20 higher. In many
cases it is impossible to gain root access, and every task beyond
the computer’s basic functions must be attempted as a separate
check to destroy, repair, disable, or manipulate modules or
countermeasures. If a firewall has been set to have a different set
of authorized users with root access, you must gain root access
to it separately. Once you have root access to a computer, you can
alter who else is granted root access with a successful Computers
check to hack the system.

You cannot take 10 to get root.

===== Hack System =====

You can use Computers to hack a computer system to which you
don’t already have access. Hacking a computer system typically
takes complexity/2 full actions. You can cut
this time in half (to a minimum of one full action) for every 5 by
which you increase the DC of the Computers check. If you succeed
at the check, you gain access to any part of the computer that is
not behind a firewall. This allows you to use the
basic functions of the computer), and to make further checks that
require you to have access. Accessing parts of a computer behind
a firewall requires an additional Computers check for each firewall.

If you fail a Computers check to hack a system, you might
trigger a countermeasure, if one has been installed. If you take 20
on a Computers check to hack a system with countermeasures
without first disabling or destroying them, the countermeasures
are automatically activated.

You cannot take 10 to hack a computer.
