Okay, I have the blurb on the memory boards for ATARI 800:

      256K:  $149
      512K:  $199
      1Meg:  $349

      To make this useful, you will also need a special version
      of TOP-DOS.

These are available thru:

	     Gordon Andersen
	     3042 Millar Ave.
	     Santa Clara
	     CA 95051

	     Tel. (408)-247-4794


The 512K Board:

   The board I have definately looks like it came out of someone's
garage, but it does work well.  I am very pleased with it.
   Apparently it conforms to the AXLON format for bank-switching,
but I haven't had a chance to confirm this, as I am not exactly sure
where & thru what memory locations it does its bank selection.  
   One problem that I did have was with my memory boards.  I had an 
early 800, with 1 16K board and a 32K RAMCRAM.  It will not work with
the RAMCRAM, cuz the RAMCRAM has to be in the first slot for a 32K
machine, and in the second slot, behind a 16K board for a 48K machine.
The 512K board has to be in the second slot, with a 16K board in
front and behind.

The Version of TOP-DOS:

   TOP-DOS has always been one of my favourite DOS's in spite of
consuming more memory than usual.  I have an early version which
only allows me to set up a double density ramdisk of 1955 sectors.
The version you will get enables the memory to be set up as any
ombination of different ramdisks.  It includes many other features,
the most useful of which is to be able to move the RAMDISK to
drive 1, where it then intercepts any calls to the real D1:.  This
is real handy.

All usual disclaimers, I am not associated with these people,
but like the product.
