/*
HP48: graphical calculators by Hewlett Packard.
Two main series: S series & G series.
Each series is subdivised into an 'expandable' model (SX,GX) and a
cheaper 'non-expandable' model (S,G).
Timeline:
- 1990-03-06 HP48SX (discontinued in ????)
- 1991-04-02 HP48S (discontinued in 1993)
- 1993-06-01 HP48G (discontinued in 1999)
HP48GX (discontinued in 2003)
- 1998-03-30 HP48G+ (discontinued in 2003)
Common characteristics:
- HP family name: Charlemagne
- CPU: Saturn, 4-bit processor, chip version: 1LT8
- BUS:
. 20-bit address bus
. nibble (4-bit) addressable
=> 512 KB address space (i.e., 1 Mnibbles)
. daisy-chained modules
- Screen: 131x64 LCD, 2-color, 64 Hz refresh
- Keyboard: 49 keys
- IR I/O port
- 4-wire serial I/O port
- 1-bit beeper
- Power-source: 3 AAA cells
- Continuous memory
S series specific:
- Clarke IC
- clock speed: 2 MHz
- 256 KB ROM (various revisions, identical in S and SX)
- S model specific:
+ Codename: Shorty
+ 32 KB RAM base, not expandable (in theory)
+ no expansion port
- SX model specific:
+ Codename: Charlemagne
+ 32 KB base RAM, expandable to 288 KB
+ 2 expansion ports (port 1 and port 2)
up to 128 KB RAM per port, can be merged with base RAM
G series specific:
- Yorke IC
- clock speed: ~4 MHz
- 512 KB ROM (various revisions, identical in G and GX)
- G model specific:
+ Codename: Alcuin
+ 32 KB RAM, not expandable (in theory!)
+ no expansion port
- GX model specific:
+ Codename: Hammer
+ 128 KB base RAM, expandable up to 4 MB (banked)
+ 2 expansion ports
. port 1: up to 128 KB RAM, can be merged with base RAM
. port 2: up to 4 MB RAM, in 32 banks of 128 KB, cannot be merged
- G+ model specific:
+ Codename: Plus
+ 128 KB RAM, not expandable
+ no expansion port
HP49 G:
similar to HP48 G with the following differences:
- 2048 KB flash ROM (re-writtable)
- 512 KB RAM (not expandable)
- Keyboard: 51 keys
- no IR I/O port
- rewritten optimized OS makes the HP49 G much faster than HP48 despite
having the same CPU and clock rate (4 MHz York Saturn)

/*
More about memory.
The base RAM is treated as NVRAM: stored in a .nv file in your nvram
directory.
When first starting the emulator, or after nvram file has been deleted,
you'll get a "Try to recover memory?". This is expected.
Answer NO (F key): there is nothing to recover, but it will setup the
system-reserved RAM part correctly.
If the emulator is shut down properly (i.e., when the calculator is
not busy), the message should not appear next time it is run.
All the variables and port 0 should be conserved (in the .nv file),
but not the stack.
Stopping and restarting the emulator loosely corresponds to hitting the
reset button.
Expansion RAMs are treated as images, not NVRAM.
The -p1 (resp. -p2) image option allows mapping some file to port 1
(resp. port 2).
The file size should be between 32 KB and 128 KB (or 4 GB for port 2 on GX)
and be a power of two.
*/
/*
More about serial connection.
Normally, files are exchanged by serial connection to a computer running a
kermit communication program (xmodem is also allowed for the G/GX).
We emulate both the serial link and the communication program.
Thus, the emulated HP48 can directly upload/download image files.
The -k image option corresponds to the kermit protocol (SEND and RECV
commands on the HP48).
The -x image option corresponds to the xmodem protocol (XSEND and XRECV
commands on the HP48).
