Hi,
> Yes, the other markings are a block "S" signifying it's a Signetics
device and the number 2203 and below that
>9247V.
This means datecode 1992, week 47.
Does the chip show this?:
==============
S
4517535
2203
9247V
==============
In that case the 2203 probably is the partnumber, not
the 4517535. Both codes are unknown to me.
