chip identification

[Curtis H. Wilbar Jr.]

Trying to ID some chips I pulled from various pieces of equipment.

I have a cpu? I pulled out of a modem ... Signetics
SC80C31BCPN40.  This would appear to be an Intel 8031 based
cpu.  But does it have an internal ROM/etc that would preclude
its reuse ?

I have 3 chips now in the trash pile... I believe they are OTP EPROMs
(and since used, are no good).  MX 27C1000PC-70, ATMEL
AT27LV256A, and AtMel AT27C010-70JC.

Lastly I have what I think is EEPROM.  SST PH29EE010-150-4CF.
I believe this to be a 1Mbit EEPROM. 

Searching google for chip part numbers is paramount to useless
due to all the chip vendors advertising....  there has to be a better
way....

So, beyond looking for better ways to search for chip data/datasheets,
can anyone confirm the identification of the above chips ?

Is an 8031 cpu 'fun' to play with ? :-)
