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
