Thank you funkytunaa, GOAOZ and tf1.
@ funkytunaa - both PC and DVD are IDE, but the pins may not match up. I just don't know how to change them.
@ GOAOZ - There are slide releases underneath, but those are for the battery. I've unscrewed several thingies but it didn't allow the DVD drive to slide out. The new drive comes with 2 fascia plates, hopefully one will fit, otherwise I might be able to reuse the old one if the clips match up.
@ tf1 - I saw that post on fixya.com and emailed Anthon and he replied, "I could not revive the Acer, so it is still lying taken apart on the shelve behind my desk.." which made me continue searching.
