Netbook input levels (for EKG)

[VibroKing$]

Hi to All

I' have build an EKG with INA121 & OPA 2604
(schematics coming soon, based on SLAA280A & SBAA160 Texas Ins.)

And I have tested this with a Desktop PC connected with on-line input (green Jack), ant It works very good.
(For isolate the EKG (battey-supply) from mains PC connection I have used an ISO124 very much expensive)

now I would like to connect the EKG to an aspire one,
(and eliminate the isolation stage ISO124)
but on this netbook I have only mic. input.

Which is the level input of mic-in line (rose jack) ?

Thanks !
