8.10 Atari Ramdisks - An (incomplete) Overview:
[This is version 2.10 from October 2003]

Right from the start of the Atari 8-bit computer era in the late 70`s,
Atari users wanted to have as much RAM as possible (or as their purse
could afford). Having a 16k machine with a tape device was nice and
cheap, but having full 48k or 64k and a floppy drive was much nicer
(and very expensive). Thus many Atari users began to create selfmade
RAM extensions and enhancements, just to save some money. Also a lot of
firms provided extra RAM, RAM enhancements, RAM extensions and Ramdisks.
Besides Atari there were (and still are) quite a lot of producers,
manufacturers, distributors and authors of such RAM enhancements...

This "short" and incomplete overview does not provide any docs or manuals,
but gives some info about the various Ramdisks on the market. Since these
notes are written by me, they will merely contain the information I have.
And as you all can see - it is still incomplete. So any help and extra
info, as well as corrections, are very welcome. It would be nice to see
this text & info growing. For now let us start here, the info-section is
divided into 8 groups:

1) Name (Name of the RD, e.g. Megaram 2 or Rambo XL or MIO, etc.);
2) Vendor/Author (or distributor, manufacturer, producer, etc.);
3) Size (size of the Ramdisk only; NOT the full computer memory);
4) [Bankswitching] Area (for XL/XE computers usually 4000-7FFF);
5) Banks (hexadecimal input count, as in MyDOS or RAMDTEST.BIN);
6) Control Bits (which bits are used to control the Rambanks);
7) Port (control Port - usually Port B for XL/XE machines);
8) Notes (any extra info, comments, miscelleanous things, etc.);

If you wish to add any other type of info, let me know. The above
information should be enough for most programmers to support a RD in
their programs (especially to support more than just one type of RD).
Hopefully future programs will take care about this info or just use
a small setup program to setup any kind of RD. Now let me begin:
