Please help identify this chip

[snossage]

Hi, new member here! I have a large collection of chips that I intend to start listing on eBay, I'm having trouble identifying this one and would appreciate some help. Many thanks in advance.

May I also ask advice about this one? I have literally thousands of different chips from a friends unwanted collection. I understand that ceramic ones can be more interesting but this one has lost its vital statistics. It has only "98(A)" on the back.

Is it now not collectible, assuming it had interest to begin with?

First chip was made by (or for) Burroghs, may be a ROM chip but not sure

Second chip is a National Semiconductor INS8080AD
.... but without writings loses all its value (about $25/$50 with good writings)

Thanks for that, so far this is the only one I have found that is missing its particulars!

Advice - put them all top down on a scanner and scan the shot then post it.

Good idea but will take a while to do. I will be interested to know if any are collectible, I have very little knowledge in this area!

Is the purple chip above of any interest do you think?

[Vlasta]

It s not a CPU but someone would certainly collect this.

Maybe start with the white ones then.
