HP-33E Missing Pin on Memory Chip

[mikemorris]

Hello everyone. I have a new question for you all today. I have an HP-33E which visually looks to be in pretty good shape with just a few very small spots of blue from corrosion. However, it shows no life when energized. I've taken it all apart and found a little surprise. There seems to be a pin completely missing from one of the memory chips. Its a little hard to see from the outside of the PCB sandwhich, but when you take that apart it becomes very obvious. I think it is VCC for that chip. This may not be the only problem but it is probably a serious issue. Any comments or suggestions would be welcome:
- Have you seen this sort of thing before?
- Any suggestions on how to fix?
