Help identify the chips - part 2

[Trogdor]

Hey guys, up for a challenge?

I came across the "Help identify the chips" thread last night, and I decided I would make my own, since I have some of those strange IBM metal-covered chips. So I took pictures and made my own little web page:

http://www.geocities.com/segaguy84/chips/chips.html

I have put several chips that I couldn't identify or didn't feel like trying to identify in there. You can try to identify whatever you want or none at all, it's up to you. I am mainly interested in figuring out what those metal-covered IBM chips are.

Thanks!

(Second edit: Changed the link to point to my secondary website, where the chips.html page will now reside.
Third edit: Added info about second and third edits.)

I hate IBM chips - they'are impossible to identify. Therefore I will go directly to section 3:

AM9265DPC34567 - 8KB ROM (?)

P8255A-5 - Programmable Peripheral Interface

AM9517A-5PC - DMA controller

MK38036N-25 - ???

D8284A - clock generator

D8288 - bus controller

D8253C-5 - Programmable Interval Timer

P8259A - Programmable Interrupt Controller
