Trying to find old 8k sram chips for HP-75c calculator pod
<< < (8/8)
RichardM:
Correct. I am just filling empty spaces. I have used 5 x new 8k chips with 55ns speed and they work fine.

Thanks everyone.

He said he would have to unsolder the SRAM chips from the scrap board he is offering for salvage, not from the HP.

I think newer SRAMs are quite a bit more reliable than the ones made in the 1970s and early 80s. RAM is one of the most common failures I encounter on arcade games.
