   Dave, since the A2630 board uses 16 256x4 chips to make 2 megabytes of RAM,
then(32 bit RAM), then isn't that actually 512K of actual RAM.  Since each
"thing" needs 32 bits then that means it can only hold 512 thousand "Things"
since each one is 32 bits long?  Is that correct?  And if so, or not so, how
much RAM will be left over after your SetCPU program copies Kickstart into 32
bit RAM?  
      
      
  Another question of you don't mind.  I have a 2000 with 1 meg agnus, 2
megabyte Micron RAM board and XT Bridgeboard.  So that's 3 megs of RAM.  With
the XT Bridgeboard my maximum RAM is limited to 6 Megs.  Well, the quesion is,
if I buy your 2630 board with the 2 megs on it, expanding my system to 5
Megabytes of RAM (3 16bit and 2 32bit) can I add the two extra megabytes of 32
bit RAM to the 2630 board and map it somewhere else to avoid the 6 megabyte
RAM limitation set by the XT Bridgeboard? (to bring it to 4 megs 32 but RAM
and 3 megs 16 bit RAM).?   Thank you for all your help and I hope you continue
to stay with Commodore because you do a marvelous job designing the hardware,
2000, 2620, 2630 etc.
