Diablo part numbers?

I snagged a big old diablo daisywheel printer here the other day, pulled the boards and mechanism out, and got rid of the case etc. right off, so there's no model number, which I probably should've written down at least :-(. Anyhow, I'm finding good numbers on the transistors and such, but a lot of the chips all have what seem to be diablo part numbers on them and not a whole lot else. Anybody know where I might be able to cross some of this stuff over to find out what it is? -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.
