Cyberdecks

Cyberdecks have certain attributes. These attributes determine the basic abilities of your icon/persona. The basic cyberdeck attributes are Firewall (software), and System(CPU).
Cyberdecks and Icons   Icons, including those generated by cyberdecks and IC, have stat blocks similar to those of flesh-and-blood creatures, with some alterations. Below is the basic stat block.
You only can run a maximum level auto program that is equal to or less than your system.

Ability Scores

All icons have the ability Scores of Strength, Dexterity, Constitution, Intelligence, Wisdom, and Charisma.

To determine the Strength, Dexterity, and Constitution scores of an icon, multiply the System rating by 5 and divide those points among the three ability scores. Off-the-shelf decks have fixed ability scores, but for an increase in price, these can be adjusted. Deckers typically just run a Variable Ability program. In no case can one of these ability scores be reduced to less than the System rating.
Can you do this yourself with a Computer Use( Data and OS) DC 15+ Tier

Intelligence and Wisdom are equal to the operator's scores (assuming a (meta) human operator) or the System rating x2 for IC and similar programs.
(Meta) human-powered icons have Charisma scores equal to the operators. Autonomous icons (IC) have Charisma scores of 1-2. These constructs are not self-aware

Saving Throws

Fortitude saves are equal to Firewall + Constitution modifier if any.
Reflex saves are equal to Response + Dexterity modifier if any.
Will saves are equal to System + Wisdom modifier if any.
All these weight 5 lbs.

Upgrading decks

You can upgrade the attributes of your computer systems individually. You can never increase the system over x2 the starting value. The set cost is 10% of the value of the deck original in the table above(regardless of what you for it)

Purchase the upgrade

Old number	New number	Additional Cost
1	3	none
3	5	standard 1000 cr or 10% of deck original whatever is lower
5	7	standard 5000 cr 10% of deck original whatever is lower
7	9	Add 10% of the total value of the deck now
9	10	Add 15% of the total value of the deck now
10	10+	Add 20% of the total value of the deck now

If you wish to install the upgrade yourself, make a Craft (electronic) check. The DC for this check is 20, and it takes 60 minutes. Reduce the time by 10 minutes per 5 points over DC 20. If you wish to have it installed, well, you should try and find a place that will include it as part of the package (30% chance). Otherwise, you will have to pay 1000 cr or 5000 cr if don't have a license and hope they don't report you.

Creating New Decks

The knowledge to create new designs of cyberdeck was lost, this is PL 8 tech to access the WWW you need PL 8 PCs, which do not exist anymore after the Ai wares. These decks are strictly controlled and you need to be a licensed cyber specialist to be caught with one. There is a 4-year jail term for having one and not having a license. They use 10 charges an hour but like all PL 8 items need access to the substation to charge. Most licensed users are in the cities which have access to this regularly.
If you somehow get access to the specs of a new desk you would need craft (cyberdeck) to build one and the min rank is the firewall number the specs use to build it.
