I find it enjoyable to disassemble the drives that I want to dispose of. I take all of the metal bits and throw them in my scrap metal recycling bin. I throw the boards in my electronics/e-waste recycling bin. I used to keep the magnets, but I have a pretty good magnet collection now and, with

Hello everyone, This is a longshot, but I was wondering if anybody has or knows someone who might have a very specific HP part. It's the HP E3417A, a PQFP132 PGA interposer for some HP emulation/debug preprocessor stuff for CPU32 (among other 132 pin QFP). Basically I came into an HP logic

Anyone have advice on making thermite? Ingredients, sources, proportions? The internet seems to think that just using aluminum powder with ferric oxide is relatively hard to ignite, and that some manganese dioxide would help with that. Without spending too much time shopping, it looks like I can

I grabbed a 11/60, 11/35 system manual. wanting to see hot power was set up in the BA11-D and -K, only to find it dealt with the BA11-F only. It does state the H754 in used with the MF11-U/UP. needless to say, there are different plugs for slot "E" and possibly a change or a jumper. I will look
