Do you have military grade chips in your Amiga?

Where did this DoomMaster character come from and why does he pass himself off as an expert??

There are 4 military spec Amiga custom chips on eBay right now.  Go have a look.     :-D

Are you refering to these?

If so, then I HIGHLY doubt these are MIL-SPEC parts.  It's much more likely they are in a cer-dip package simply because they have high power disipation like the good old VIC in my C64.  Why go through all the trouble of designing a part that can operate from -55C to +125C when the part will never be subjected to these extreams?

You have to remember that these chips where designed and built in the early eighties.  They had alot of transistors in them for the time.

Too bad locating a datasheet for these components is neigh on impossible.  Anybody have the foggiest clue where one might be sourced?

You do NOT know what you are talking about when it comes to these chips.  

Until you provide some solid proof (i.e. a datasheet with environmental limits, statements from MOS employees or Amiga designers), you are on shakey ground.  Financial logic is against you.  Designing the Amiga custom chips to MIL-SPEC would have been VERY expensive and totally unnecessary.

The Amiga custom chips ran at a high clock speed for the time.  Transistors then were not as efficient as modern transistors.  Everytime a transitor changes state, it disipates power as heat.   Combine high power disipation at every switch with lots of transistors switching millions of times per second and you get a lot of heat.  The only safe way to disipate that heat is through a ceramic package.  Why wasn't the 68000 ceramic?  Motorola had a MUCH better process than MOS.  Money can do that.   Simple as that.
