+
+ Exidy Sorcerer system driver
+
+ The UART controls rs232 and cassette i/o. The chip is a AY-3-1014A or AY-3-1015.
+
+
+ port fc:
+ ========
+ input/output:
+ uart data
+
+ port fd:
+ ========
+ input: uart status
+ bit 4: parity error (RPE)
+ bit 3: framing error (RFE)
+ bit 2: over-run (RDP)
+ bit 1: data available (RDA)
+ bit 0: transmit buffer empty (TPMT)
+
+ output:
+ bit 4: no parity (NPB)
+ bit 3: parity type (POE)
+ bit 2: number of stop bits (NSB)
+ bit 1: number of bits per char bit 2 (NDB2)
+ bit 0: number of bits per char bit 1 (NDB1)
+
+ port fe:
+ ========
+
+ output:
+
+ bit 7: rs232 enable (1=rs232, 0=cassette)
+ bit 6: baud rate (1=1200, 0=300)
+ bit 5: cassette motor 2
+ bit 4: cassette motor 1
+ bit 3..0: keyboard line select
+
+ input:
+ bit 7..6: parallel control (not emulated)
+ 7: must be 1 to read data from parallel port via PARIN
+ 6: must be 1 to send data out of parallel port via PAROUT
+ bit 5: vsync
+ bit 4..0: keyboard line data
+
+ port ff:
+ ========
+ parallel port in/out
+
+ -------------------------------------------------------------------------------------
+
+ When cassette is selected, it is connected to the uart data input via the cassette
+ interface hardware.
+
+ The cassette interface hardware converts square-wave pulses into bits which the uart receives.
+
+ 1. the cassette format: "frequency shift" is converted
+ into the uart data format "non-return to zero"
+
+ 2. on cassette a 1 data bit is stored as a high frequency
+ and a 0 data bit as a low frequency
+ - At 1200 baud, a logic 1 is 1 cycle of 1200 Hz and a logic 0 is 1/2 cycle of 600 Hz.
+ - At 300 baud, a logic 1 is 8 cycles of 2400 Hz and a logic 0 is 4 cycles of 1200 Hz.
+
+ Attenuation is applied to the signal and the square wave edges are rounded.
+
+ A manchester encoder is used. A flip-flop synchronises input
+ data on the positive-edge of the clock pulse.
+
+ Interestingly the data on cassette is stored in xmodem-checksum.
+
+
+ Due to bugs in the hardware and software of a real Sorcerer, the serial
+ interface misbehaves.
+ 1. Sorcerer I had a hardware problem causing rs232 idle to be a space (+9v)
+ instead of mark (-9v). Fixed in Sorcerer II.
+ 2. When you select a different baud for rs232, it was "remembered" but not
+ sent to port fe. It only gets sent when motor on was requested. Motor on is
+ only meaningful in a cassette operation.
+ 3. The monitor software always resets the device to cassette whenever the
+ keyboard is scanned, motors altered, or an error occurred.
+ 4. The above problems make rs232 communication impractical unless you write
+ your own routines or create a corrected monitor rom.
+
+ Sound:
+
+ External speaker connected to the parallel port.
+ There was a dac you could make instead, this is supported.

+
+ ******************************************************************************
+
+ The CPU clock speed is 2.106 MHz, which was increased to 4.0 MHz on the last production runs.
+
+ The Sorcerer has a bus connection for S100 equipment. This allows the connection
+ of disk drives, provided that suitable driver/boot software is loaded.
+
+*******************************************************************************
+
+Real machines had optional RAM sizes of 8k, 16k, 32k, 48k (officially).
+Unofficially, the cart could hold another 8k of static RAM (4x 6116), giving 56k total.
+
+On the back of the machine is a 50-pin expansion port, which could be hooked to the
+expansion unit.
+
+Also is a 25-pin parallel port, allowing inwards and outwards communication.
+It was often hooked to a printer, a joystick, a music card, or a speaker.
+
+We emulate the printer and the speaker.
+
+Another 25-pin port provided two-way serial communications. Only two speeds are
+available - 300 baud and 1200 baud. There is no handshaking. This protocol is
+currently not emulated.
+
+Other pins on this connector provided for two cassette players. The connections
+for cassette unit 1 are duplicated on a set of phono plugs.
+
+We emulate the use of two cassette units. An option allows you to hear the sound
+of the tape during playback.

+NOTES (2011-01-09)
+1. Converted to MODERN driver as much as possible.
+2. Added 2 defines for work that needs doing at some time:
+- SORCERER_USING_RS232 - this is for when we can connect a serial interface.
+- SORCERER_USING_DISKS - the disk controller I believe most likely to be a
+ 'Micropolis Floppy Disk System' at 143KB on 13cm disks.
+ There was a hard-sector system (top of ram = BBFF),
+ and a soft-sector system (top of RAM = BDFF). You could
+ use alternate systems (since you could attach a S-100
+ unit), so not sure how this could be developed. The
+ Micropolis seems completely undocumented in the technical
+ sense. When using the hard-sector system, in the monitor
+ enter GO BC00 to boot the disk. No idea how in other
+ disk systems.
+
+ Note that the code within the defines has NOT been
+ compiled or tested. You are on your own!
+
+
+NOTES (2011-08-08)
+1. SORCERER_USING_DISKS removed, replaced with a new driver "sorcererd".
+ This is disk-enabled, allowing CP/M to run.
+ To initialise the disk system, you must enter
+ GO BC00
+ after the computer has booted. It is not particularly
+ stable, so be prepared to cold boot whenever something
+ goes wrong.
