   Bob,   
      
   When my first 486VL-BUS was built I asked for a Orchid VL-BUS   
   Video board because of my reading of it in Computer Shopper Magazine..   
   Some years later I got a SIIG VLB Controller Card and put it in.

   16MB of RAM was $540 USD in 1994, but later when the price lowered   
   for TAM I got another 4 SIMMs and now have 32MB RAM.

   Thank You but I'll pass.    
   I still have the 486DX33 that came in the box but later was given   
   a 486DX2-66 which is still in the box.   
   I kept the 33 as a spare just in case........

   Thanks for recommending the link.   
   I collect all the info I can about anything that interests me.

   It probably would.   
   A file I have says the Shuttle HOT409 can take two styles of   
   Pentium Overdrive CPUs up to 66Mc/s - P24D and P24T .   
      
   Wasn't it the P66er that couldn't ADD 2+2??????????   
      
   Or was that the P60? Yeah I think that was the critter that   
   made the Headlines that Intel didn't want to read.
