@th what are you making?
@th is that the underside under a microscope without decapping? it's so pretty. is it a common issue for the bond wires to have detached over time?
@fbz this soviet-era SRAM chip was selected for its easy-to-remove metal cover so that the die can be exposed to light. it's as old as I am and of unknown provenance, so I was worried about possible mechanical failures.
@th so is it EPROM that can be wiped with UV light?
@fbz this is just a normal SRAM chip in a ceramic package. the UV EPROM typically have quartz windows so that you can expose the die to the eraser light without dust contaminating the inside.
@th gotcha. very cool.
@th Is it fixable? (Or: What effort is required to fix it?)
@th this is where making friends with an ant earlier in the story is going to come in handy
@th (is it an address or data line you can just let float?)
@phooky if it is the same pinout as the i2102, then it is an address line. luckily I bought lots since I expected to break a few.
@th oh that looks fun
@th Whoa - are you building a board for this?
Bond wires look ok!
