The IBM is interesting because of the "IBM 51"-marking.
IBM-chips mostly wear "IBM93", I guess it indicates the factory.
A picture of the whole board and of the board P/Ns would
help much to identify the chip!

By part number, 44H548, I believe it's an AS/400 model 400 CPU card
processor it's an early Cobra with 625-contact and measured 32 mm by 32 mm
right? |

I agree it is most likely a Cobra/A10-processor,
the predecessor of RS64.
