   > Hi. I had a question about upgrading my Atari 1040STE computer. I currently   
   have 4 MB of RAM in it and a 16 MHz CPU (standard CPU, of course, for this   
   type of Atari ST). I wanted to know how I could find a way to beef up the RAM,   
   see how I could    
   integrate a high-end graphics cards for it and find a way to improve the speed   
   of the computer overall. I know the STE I have can address a RAM clock speed   
   of 16 MHz, but was wondering how much RAM can really be installed in an   
   1040STE.   
      
   	With the 24 bits of the address bus, it is 16MB max.   
   	But some addresses are reserved for ROM and peripherials.   
   	If you stop at $E0.0000 (start of ROM in the STE), then you have 14MB.   
      
   > I also downloaded how to build the ET4000 graphics card off of the Atari ST   
   Hardware Hacks website by Marcello "Vezz" Vezzelli, but I am wondering. Can an   
   STE can be fitted with a more advanced card than that, as well as certain   
   expansion slots (like    
   PCI and AGP) to improve expandability? Is there something similar to a CT60   
   for the ST to upgrade the CPU? If not, can it ever be developed somehow? There   
   must   
   > be a way to integrate the technologies together. If not now, perhaps in the   
   future.   
      
   	The problem you'll have with every standard PC card is that the   
   encoding of the pixels is not the same as in the STE.   
   	So, all off the low graphic routines of the VDI (particularly the   
   LineA) must be rewritten to fit the card specifications.   
      
   	This is a tremendous work..! (put/get pixel, draw line, draw rectangle,   
   fill rectangle, fill polygon, write text, blitblock, etc...).   
      
   	Else, there is a card for the ST that replaces the 68000 with a 68030,   
   the PAK/3. But hard to find...
