Mystery HyperTech Chip?

[BLACK MAGIC RACING]

I found a chip today in a box of parts that i got from a friend.

What it says is as follows:

SN# 0 7 4829
Hypertech (c) '89
PT# 41 373


And that's it. Any idea what it might be?

Based on the 89 date on it. I'd say it's a good chip for a new image.

glue a magnet to it and stick it on your fridge
