Banks: Mapped to $A000-$BFFF.
Emulated: Atari800

Std 8KB carts (right slot)

Information missing.

Std 16KB carts

Banks: Mapped to $8000-$BFFF.
Emulated: Atari800

OSS carts

Banks: Contain 3-4 4KB banks. One of the banks is mapped in $B000-$BFFF. Other banks are mapped to $A000-$AFFF.
More information in article below.
Examples:
Action! (1 KB GIF)
MAC/65 (2 KB GIF)
Basic XL (1 KB GIF)
Basic XE (2 KB GIF)
Emulated: Atari800 - Action & MAC/65. I've added Basic XE & XL to my experimental emulator.

SDX carts

Banks: Contain 8 8KB banks.
SDX: Access to D5E0-D5E7 turns on banks 0-7 in $A000-$BFFF area. Access to D5E8-D5EF turns the cart off.
Diamond: Same, addresses are D5D0-D5D7 and D5D8-D5DF.
More information in article below.
Examples:
SDX (3 KB GIF)
Diamond (3 KB GIF)
Emulated: My own Atari800 experimental version. Information above is enough to make it work in Atari800.

MUX OS

See article below.
Emulated: Unemulated.

R-Time 8

See article below.

Emulated: Atari800 - read only is enough.

XEGS 32KB carts

Banks: Contains 4 8KB banks. Bank 3 is mapped at $A000-$BFFF. Banks 0-3 are mapped to $8000-$9FFF by writing to $D5xx.
Examples:
Into the Eagle's Nest (4 KB GIF).

Great source of information about memory and cartridge mappings is in following article by John Picken. It contains DOS tables so that it is somewhat hard to read in browser. Click here (45 KB TXT)
