Full Version: Cyberlimb integrated devices and ECU
Dumpshock Forums > Discussion > Shadowrun

I was just wondering about this (haven't found a clear ruling anywhere):

M&M clearly states that alpha-grade or better cyberlimbs provide less space for implanted devices (ECU).
Is the reverse also true?

For example: datajack
Regular grade .5 ECU / .2 Essence
Alpha grade .4 ECU / .16 Essence ?

If so, then theoretically you'd optimize the use of your available cyberlimb ECU by getting a regular-grade limb replacement and getting all delta-grade implants (yeah, like that's ever gonna happen grinbig.gif), right?

And while I'm at it, I'll duct tape a 10K nuyen.gif cyber-optic triangulation unit to a 75 nuyen.gif plastic handgun.

No, the reverse is not true. ECU's only come in 0.25 packages so -maybe- a DeltaGrade Datajack would be 0.25 ECU, but any other grade is stuck at 0.5.

PS. I've no idea what Crusher Bob is talking about... I just assume he's drunk and it's late there. nyahnyah.gif

It's from cyberpunk2020. There were these gunsights called cyber-optic triangulation units, that were basically cyber-eye/gunsight things that you attached to your gun. This allowed you to do all sorts of nifty tricks since you now had a 'barrel's eye' view in addition to your normal vision. They were grossly expensive. Now compare to the mostly plastic guns in cp2020... you could get chinese knock offs in the 25-75 dollar range. They were cheap, came in a variety of designer colors, and only blew up some of the time.

He summed it up pretty well. Minimum ECU unit is .25, and the reverse isnt true.

So the only benefit using alpha-grade or better cyberlimb components provide is reduced essence costs for DNI, datajacks and such... I figured as much, just wanted to be sure.

Thanks! smile.gif

Don't forget, you don't need to spend essence for DNI in a Cyberlimb if you have a Datajack in the same Cyberlimb. DataJack can act as 3 DNI's in addition to the normal uses of a Datajack.

pagenumber for the not needing DNI if datajack in cyberlimb stuff sphynx? from what i have read the DNI is a link from the limb storagespace to the brain so that anything either allready able to be used with DNI or that can be modefied can be hooked up with no limit. i dont see that a datajack mounted in a limb includes a DNI job, alltho it may be logical as the only job for the datajack is to be a general access port to the brain...

Pg 38 M&M: Simply put, a DNI is a dedicated datajack connection to a specially modified piece of equipment:

Pg 46 M&M: Interconnectivity.

It all depends how you round off the numbers. You can either round off after totalling all of them, or you can round off each as you put them in. So I would rule logically that you can lower ecu cost. Personally, I don't see why rounding off numbers is really needed, unless you find a .33333333....

However, there is no canon rule stating that better grades do lower the ecu cost of implants, therefore, from a purist's perspective, I would rule that they cost the same in ecu.

And in a related question:

When you buy Hydraulic Jacks and Cyberskates, are you buying jacks and skates for both legs or just 1?

The concensus is that you are purchasing both for the listed cost and Essence.

So if I had 1 meat leg and 1 cyberleg, the total cost of rating 5 hydraulic jacks would be, 1.225 essence & 3.25 ecu. Correct?

you cannot put hydraulic jacks into meat legs

Of course you can! They have a listed essense cost of .75 + .05 per level, if I remember right. That cost goes down if you implant them in a cyberlimb.

I believe that you are confusing a DNI with a router. A datajacks three router ports are not DNI slots.

[CORRECTION] Zazen's quote here is correct. A dni is a dedicated datajack. Therefore, datajacks are dni on steroids. A router is dni too. Its all one big happy family.

The only problem with it is a datajack only has 1 external port. Therefore, only 1 device from a limb can plug into it. So yes, a dni might still be needed if that external port is already in use.

in shadowtech it says hydraulic jacks must be in cyber legs, so i dunno about 3rd edition

The books aren't written clearly so I can see the confusion, but a datajack will not let you DNI-control devices unless you plug them into your datajack. A router will not let you DNI-control anything at all.

Page 22 is pretty explicit that "Routers do not allow a device to be cybernetically controlled..."

As for datajacks, they act as free three-port routers and provide no other benefit (like DNI-control). On page 46 it says:
"A device only needs to be hooked up to a datajack or router port if the user wishes the device to communicate with other devices with which it does not normally exchange data."

"Like a datajack, each router has a direct neural interface, allowing the user to to monitor and manipulate transfers between devices."
You are correct, routers do not provide dni connections, the dni is merely for the user to control the router.

At first i was confused by your statement about datajacks, but now I see that your talking about it's router ports as providing no dni benefit. This is correct.

So it boils down to this:
You need a dni implant or datajack for each item you wish to mentally control in your cyberlimb. Although the items are in the inside of the limb, they are considered external. 1 cannot work for many. A datajack gives the extra bonus of added information exchange between devices is all, not added control.
