well basically ive thought about it but never done it, and looking to do it again.
basically what i would have:
computer (mini/micro atx)
touchscreen LCD mounted in the dash in place of the CD player.
however, if it owuld be possible i would like to replace the SID display (i have SID2) also just to have that extra space within the dash to mount the LCD (fiberglass, maybe coated with a piece of cedar or something to sorta match the inlayed stuff)
however, without the SID i would be unable to see any errors, or what not. i was wondering if it was possible to possibly create a serial interface that the SID receives its info from (ecu right?) and create a program on the puter that would decode the data that is being sent by the car to the "SID" and show that on the LCD screen.
i know that it should be possible, just not sure what type of work this would require, or if anyone has done it.
