HP 53131A vs 53132A hardware differences

<< < (8/8)

ZGoode:
I'm looking to do this mod to my 53131A, but it appears to be one of the later revisions with the TSSOP flash instead of the PLCC flash.  How do I upgrade the firmware?  Do I need to remove the chip from the board to do that?

Rochester Electronics is a trustworthy source.  Unfortunately they do not do small quantity orders.  I was looking at buying from them, but they will not process orders under $250

Oh, I see - so that's why 9 would need to be ordered, to get over $250.  I understand.

I looked around and unfortunately don't see anything else of interest in the parts catalog.  It's all old legacy stuff... I wonder what their business is, the repair parts business can't be large enough to pay rent for their sizeable building.  (With a sign saying "Worldwide Headquarters" at the driveway!)
