Can anyone help identify this I.C. model?

This one has been sitting on my shelf for some time and I have no idea who made it. Can anyone help?

Great Thanks! Glad to finally know what it is. Looks like plans can be found without much trouble. Well back on the shelf for now with this little guy while I finish other projects.
