A few more chips for indentification

[gshv]

First chip - Rockwell 6800?



I have two of these, and the second chip has "7742" on the last line. On the back it says:

A6800
A
Mexico

Here is another chip:



At first I thought it was 3880 (Z80). but now I think "3880" is a date code or something like that.

And the last one. It's probably not a processor but it looks cool:



Thanks!

Yes, the first one is a 6800 CPU. Rockwell often used this kind of packaging and when I tried to find information about the Rockwell 6501 in my collection some months ago I found a website with pictures and descriptions of Rockwell 8-bit processors from the 70s and 80s. Your A6800 was also listed there. I did not bookmark the URL though

Don't know anything about the other chips.

Great, I'll try to find this page about Rockwell microprocessors.

Thanks!

Yes, I also tried yesterday but with no results. I remember it was a subpage of a university or other educational institution website and it was in english. And the last time I found it I was really searching for a long time, because I did not find any results with a query for 'Rockwell'... maybe I searched for the package type, because last summer I was gathering information about chip packaging. I hope this helps you a little bit. I will also keep on searching though.
