I have a collection of 486 parts myself. I always found that era the most interesting as it had more companies making or rebranding chips then pretty much anytime else. I've posted this pic here before but I have more types. At some point I want to make a display box for them.
That Green CPU is kinda rare in the US as they were not imported here officially.
Ah awesome! I didn't realise haha. As you can tell, I'm not too familiar with old hardware. I think I found that frequency from a quick wiki search haha.
For future reference (if you care) you can find the specs of any Intel CPU from the last 20+ years by simply searching the S-Spec code, that 5-digit code printed next to the voltage.
