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. - - - Kevin Thacker [MESS driver] - Robbbert [Various corrections and additions over the years] - - ****************************************************************************** - - 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. - -********************************************************************************/ - -#include "includes/sorcerer.h" -
