Atari A800/A5200/XEGS cart slot emulation
Atari 8 bit cart emulation
(through slot devices)
<fill me>
Emulation of the cartslot(s) for Atari 8bit series of home computers
References:
- Altirra HW reference manual 2022-07-07 edition, chapter 8;
- https://github.com/atari800/atari800/blob/master/DOC/cart.txt
- https://www.atarimax.com/jindroush.atari.org/acarts.html
Accessors to ROM are typically given in the area 0xa000-0xbfff, but some
carts (and the right slot in A800) maps ROM to 0x8000-0x9fff too
Bankswitch typically happens by accessing addresses in 0xd500-0xd5ff
Accordingly, this device offers the following handlers
- read_80xx/write_80xx
- read_d5xx/write_d5xx
Notice that these are installed in different ranges at machine start by
the drivers, so that it might well be that offs=0 for read_80xx is 0xa000!

Phoenix/Blizzard cart schemes
RD5 is special here: once disarmed it cannot be armed again from software.
TODO:
- Reset button optionally located on cart allows RD5 to be rearmed;
Notes:
- "Blizzard 4KB" note from .car specs suggests being a Phoenix in disguise,
they are definitely a better suit to use the a800_phoenix def rather than blizzard_device
given the RD4 access of latter.
- For "Blizzard 32KB" cfr. ultracart.cpp
- "Phoenix AST2K" is an oddity, according to Kr0tki on AtariAge forums:
"AST 2000 was two cartridges in one - it contained an AST Utility cartridge,
and a cartridge for Turbo 2000 (another turbo system popular in Poland).
The "AST 2000" contained a 16KB ROM and a two-position switch, which allowed to choose between
one of two 8KB banks. [...] the second half (Turbo 2000) [...] contained a capacitor that
automatically switched off the cartridge from memory after a certain time [...]"

/**************************************************************************************************
Williams cart scheme and variants
- Regular Williams cart maps ROM bankswitch to $x0 - $x7, RD5 disables with A3. x is mirrored.
- Express carts maps x = $7x, bank map is xor-ed
- Diamond carts maps x = $dx, bank map is xor-ed
- Turbosoft carts raises number of banks to 16, moves RD5 disable to A4 instead of A3
- All CCTL accesses works both on reading and writing.
