My beloved Powerbook´s display is dead, the cold cathode lamp refuses to ignite even after forced "sleep - awake" cycles. I dont´t want to spend additional money in buying a "new" display for it because the machine has left its best days behind and since several months is showing other signs of hardware decay (worn casing, signs of damaged ATI graphics chip).

I am in the process of searching a cheap external display and my initial observation is, that modern displays only offer DVI-D (digital) ports. Apple technical documentation only states "DVI port", it does not specify, if it´s an DVI-D (digital), DVI-I (integrated, both analog and digital signal) or DVI-A (analog) port. Does anybody know, which kind of port is provided with the 667 MHz DVI Tibook?

Its DVI-I so it will do DVI-D just fine. Or VGA via an adaptor.

Is there such a thing as DVI-A? I can't see the point.
I have plenty of more important things to do, if only I could bring myself to do them....

There's no such thing as DVI-A.

The port is DVI-I. You can tell because of the blades on one side of the connector shaped like a +. These are the analog pins (RGB) for a VGA connection.

All monitors with DVI will have DVI-I.

Thanks for your answers so far.

There also seems to be an analogue flavour of DVI out in the tech jungle:

How to Recognize a DVI Cable
There are two variables in every DVI connector cable, and each represents one characteristic.

The flat pin on one side denotes whether the cable is digital or analog:
A flat pin with four surrounding pins is either DVI-I or DVI-A
A flat pin alone denotes DVI-D

The pinsets vary depending on whether or not the cable is single- or dual-link:
A solid 27-pin set (rows of 8) for a dual- link cable
Two separated 9-pin sets (rows of 6) for a single-link cable

NOTE: To distinguish from DVI-I and DVI-A, check the pinset. A solid 27-pin set is for a DVI-l; a separated 8-pin and 4-pin
set is for DVI-A.
Link: What is a DVI Port and what can I do with it?

According to this data given there the Powerbook´s DVI port is DVI-I

There absolutely is. I think it was intended so DVI could be the one connector to rule them all but it was never widely implemented.
