Hello, I digged into my dead HP87 and identified the issue coming from a dead power supply. At least, I hope this is the only one : I noticed that some voltages were quite weird (+12V instead of -12V in one pin...) and hope it did not fry the CPU board as well.

Just wanted to know if someone in the community would be willing to sell some HP87 parts , if not I will continue the investigation using the service manual but it may take quite some time...

thanks in advance for your feedback,

Philippe
