PACEMIPPS? (and MIL-STD-1750A) - test-drb@ccmp.vtda.org

 It says that the MIPPs ICs are standard MIPPs processors 
 but built to Mil-Standards. 
That would actually be MIPS processors.  The MIPS architecture came out of 
Stanford and stands for (supposedly) "Microprocessor without Interlocking 
Pipeline Stages".

  I've
actually got some Performance Semi 1750A chipsets...I must think of 
>something to do with them...  
 I've got a few as well. I also just found a 1753 (MMU IIRC)  
Yup. 

...
  and 1754 (I/O interface IIRC).   
Usually called a PIC (peripheral interface controller). 

Let me know if you ever want to get rid of those...I have several complete 
chipsets, but can always use spares. 

...
  In case you'r enot aware of it, the 1750 is a
"standard"
 processor that the government is trying to use in all 
 aircraft and aerospace applications. 
Well...it was the standard a decade or two ago; the standard came out around 
1980, AFAIK.  I don't think that there has been a hard requirement for 1750A 
in military contracts for a long, long time.  It's only a 16-bit processor, 
after all, and almost noone makes it any more (Performance doesn't).  It, 
like the JOVIAL programming language often used to program it, are probably 
only around for maintenance and upgrades of existing platforms.
