What chip is this??

[Mike DiMeco]

I am a newbie to this group, and to FI in general.

I have an ECM (16025321) from an '83 6 cyl. camaro.
The PROM has a bunch of numbers after the DELCO 512K...

8317 3061 06630 CE1024.

What PROM device is this? Also, this chip does not have
a window like other EPROMS. I assume I can erase it with
my device programmer just the same, or copy the bin to
another EPROM, but I can't read it correctly until I
know what device it is.
