Hi,
I found a mystery chip in a pile of stuff. Apparently, it was an AWARD
BIOS in a former life. I can read it in my EPROM programmer and it is
read
compatible with a 27C512 (64Kx8 EPROM). The contents
are consistent with
an AWARD BIOS for a PC of some sort.
However, the chip itself is rather unusual. There is no EPROM quartz
window, the manufacturer symbol is a triangle, and the number is unlike
anything I have seen before. Worse yet, I get no helpful hints on GOOGLE
when I try.
Maybe this'll help:

?
A triangle sounds like Matsushita, maybe.
The chip number is 608C62. I am guessing it is either
a One Time PROM or
a
mask ROM. Has anyone heard of this or know what
family it is from?
I've not heard of that one before.
I am hoping it was a FLASH ROM or EEPROM but I
can't seem to find anything
on this chip. Any hints or help much appreciated!

Hi Roy,
Thanks for the reply.
I reviewed your page of chip logos and the Hundai/Hynix triangle seems the
closest but even then not exact.
The logo is a perfect equilateral triangle outline.
Thanks!
