Sob
I was just removing a ROM 0 chip to read. I had it all unsoldered and was loose, but as I was pulling it out with just a little pressure and the case just crumbled and 7 pins broke off - from a HP-92 to make things worse :-(

Obviously the plastic material in these degrades too.

For future reference, even more gentler handling is required.

The IC is bricked for normal use, but luckily the pins that broke were for the display anodes and the chip still functioned and I was able to get the code from it.

I hope now that I find my way with the ROM chip replacements.

cheers

Tony
