-
- 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.
