its reuse ?
8031/80C31 is the ROM-less version of the 8051. So you're in luck.
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.
I believe that you're right, if they have no windows on them.
Lastly I have what I think is EEPROM. SST
PH29EE010-150-4CF.
I believe this to be a 1Mbit EEPROM.
Yes, search for "29EE010" on
DatasheetCatalog.com and you'll turn up
the SST part.
As far as excluding the chip-peddling sites, I spike my google search
with terms such as -buy -RFQ -qty -quantity -stock...
