I'm having trouble identifying some old chips i have. so if you could help me i would appreciate it.

here are the chips

a strange i logo not intel / 7552c (7440) white with grey traces
a amd / 2802 (7231) white with grey traces
a amd / 280259e (7224) deep purple
a mostek / mk5007p (7604) deep purple
another strange i logo / icl8052acdd (7614) deep purple
a motorola / mcm6604l (dq7649) deep purple
a motorola / mcm6810al-1 (7652d) deep purple
a signetics / 2650-l (7701) (c) white
a ami / s6810-1 (7702dh) white and grey

if you could help me id what exactly they are and why there are no references to theme anywhere as far as i have looked on the internet. google, wikipedia, ebay, and cpu or other old electronic chip sites. I would definitely appreciate it.

The 6810 chips are RAM
The 2650 is an 8 bit processor
The 8052 14-Bit/16-Bit Microprocessor
The I stands for Intercil
The MK5007P is a 7-Segment-Output Decade Up Counter
The others I don`t know.

thanks, are any of these chips rare or hard to find?

The signetics / 2650-l (7701) (c) white is hard to find but I wouldn`t call it rare. The others have early dates but don`t know if they are rare or hard to find.

If you are not a collector I would be interested in buying the 2650 if you want to sell it.
Since you are not registered I can`t PM you.
Email me if you are interested.
