**************************************************************** MB25 Learning System Release History Start Version_B_V1x (March, 2006) **************************************************************** February, 2007. Change to Software Version_C_V2x Modification: 1. Add a discrete UART to handle the USB serial data. (In previews version, USB shares the same data path with MIMIC.) 2. Remove DIP Switch because of the MB25 fully production programmable. (As the language settings can be downloaded as part of the software setup.) May, 2007. Change to Software Version_D_V30 Modification: 1. Add a new model “LS” to sperate from MB25 “Pro” previously. From now on, the features of MB25 “Writer”, “Writer Plus” and “Pro” are the same as MB20’s exactly and “LS” has the extra features such as Music, Alarm Clock and Diary, etc. (This request the MB_Comm updated to version 2.4 as well.) 2. Introduce UKBC for UK translation software. Add new command {UKCAP} to toggle the capitalization of UK letters. Default is ON. 3. Sweden language has been implemented in MB25 V30DS20. July, 2007. Change to Software Version_D_V31 (unreleased) Modification: 1. Introduce UEBC for OZ translation software. Add new command {UEBC} to toggle UEBC rules ON or OFF. Default: ON --- OZ OFF --- UK and USA. (Note: Characters larger then 0xFF can not be handled because of the limitation of the data structure defined originally.) 2. Portuguese language has been implemented in MB25 V31CS20. August, 2007. Change to All Software Version_V31xx (released) Modification: 1. Allowed USB selectable serial bit rate. The bit rate range is: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 128000 (Default is 115200). The selection will be saved automatically. Use command: {USB BR bitrate}. 2. Spanish and French have been implemented in MB25 V31AS20. 3. Lithuanian, Czech, German, Polish and Russian have been implemented in MB25 V31BS20. 4. Brazilian and Greek have been implemented and embedded into MB25 V31CS20. 5. Finnish, Swedish, Norway and Dutch have been implemented in MB25 V31DS20. 6. Allowed selectable Software Handshake of USB. The selection will not be saved automatically but could be done by using the new command {SAVE USB}. Commands: {USB HS S} --- Select Software Handshake; {USB HS H} ---Select Hardware Handshake (default); {REPORTC USB} ---Report current settings of USB. 7. There was a bug occurring while selecting the “Punctuation” in SPEECH MENU. Fixed. November, 2007. Change to Software MB25Version_D_V40SS20 Modification: 1. Add new command {RD xxx} to reset default language. Here xxx means: OZ ---Australian UK --- English USA --- American FR --- French CFR --- Canadian French GER --- German. (Note: a) It is necessary to do a hardware reset for the MB after entering this command; b) This command is not like the command {DFLN}, the language reset will become the default setting permanently until next change.) 2. Add new command {5,9 xxx} to downgrade MB model. Here xxx means: F --- Pro P --- Writer Plus W --- Writer. (Note: a) It is necessary to do hardware reset for the MB after entering this command; b) This command is acceptable only if the current model of MB is higher then xxx; c) Once the model downgraded it is impossible to upgrade back to the original without the Licences Key supported by Quantum Technology.) 3. Since UEBC rules implemented, the sequencing has been abolished (e.g. the words such as “and”, “for”, “of” etc. should written separately). So it is not necessary for the command {FB} to force the translation to grade 1. From now on, the grade level will be left as is after {FB} is turned “ON” except for English UK as this is without UEBC rules. December, 2007. Change to Software MB25Version_D_V41xxxx Modification: 1. Add above features (MB25Version_D_V40SS20) to the all sets of software; 2. Build three small tables (Epson_french_words, Epson_german_words and Epson_spanish1_char) for UK customers to learn or write some foreign characters in the normal English text. During back translation, use the command {BFC FR/GER/SP} to start a French/German/Spanish Braille translation and terminate it with the command {BFC}. For the forward translation, type commands {FFC FR/GER/SP} and {FFC} instead; 3. Fix a bug while writing “corrections” into the MB file. (This problem caused because the data type mismatch between the compilers of EZ80 C++ and Borland C++). Note: Above “Modification 2.” has been included in the MB20Version 9.31A00. May, 2008. Change to Software MB25Version_D_V42xxxx Modification: 1. Add “|[C]” and “|[NC]” of forward directive for UK software. Here: |[C] ---Turn “Contracted Number” ON; |[NC] ---Turn “Contracted Number” Off. 2. Update some rules of British “Numbers and Related Signs”. (Published by Braille Authority of the United Kingdom, 2004, Section 6.) 3. Use internal English synthesizer to speak Spanish words based on “Exception Dictionary”. (For Special Set V42AT20). Requires Spanish dictionary "Spanish1.dix". 4. Modify calculator software to match the requirement of UK customers. (Ref. “Braille Mathematics Notation” published by “Royal National Institute of the Blind”, 2005). Note: Above “Modification 1, 2 and 4.” has been included in the MB20Version 9.32A00. July, 2008. Change to Software MB25Version_D_V43xxxx Modification: 1. Add the command {GM} for GREEK software. Thus: GM ---Greek letters typed from PC keyboard will be displayed on the MIMIC (Grade 0 level); MIMIC ---Braille dots pressed from MB keyboard will be translated and displayed on the MIMIC. 2. In Calculator Mode, Newline key will be a valuable if and only if it’s pressed after t-chord (Print out current equation) command. 3. Modify Greek software to match the requirement of Greek customers. 4. Use “Right-Alt” key on the Greek PC keyboard to control Greek or English letters input (toggle). 5. MBComm update to Version3.4. Note: Above “Modification 1, 2 and 4” have been included in the MB20Version 9.33C00, “Modification 3” included in 9.33A00. August, 2008. Change to Software MB25Version_D_V44xxxx Modification: Flash load Check during downloading of the “User boot load” called by command {BLOAD} and report error messages as well. For matching this modification MBComm update to Version 3.6.(MBComm3.5 only reports error code and no error messages.) October, 2008. Change to Software MB20 Version 9.34A00 Modification: There is a translation bug if the capitalized lower-sign word appears after the SPACE letter (UK customer required). Fixed. December, 2008. Change to Software MB25Version_D_V45xxxx Modification: 1. Eeprom Writing Check during “Upgrade Software”, “Upgrade Module” and “Reset Default” operations. 2. Fix the timing problem from “I2C Clock Control Register”, Argument ‘M’ and ‘N’ has been corrected. 3. Add the “Real Time Clock Check” while Mountbatten turns on. 4. There is a translation bug if the capitalized lower- sign word appears after the SPACE letter (UK version). fixed. February, 2009. Change to Software MB25Version_D_V46xxxx Modification: 1. UEBC (toggle command) will be saved automatically. 2. If UEBC off, the separated Braille signs (such as WAS, BY etc.) did not speak properly. (Fixed) 3. The Page Numbering has been turned off automatically after the first paging marked. (Fixed) 4. In some languages (German, French and Greek) the control keys (e.g.: TB, RL etc.) were spoken incorrectly. (Fixed) Note: Above “Modification” has been upgraded in the MB20Version 9.35xxx. May, 2009. Change to Software MB25Version_D_V47xxxx Modification: 1. Fixed the bug of command {STD} (not functioning). 2. Increase the size of “input buffer” from 1K to 16K. 3. Add a command {EPD} for “Embossing PC Data”. This command is used to emboss the data at MB side which coming from PC. Once it has been issued, the data transmission and emboss will never been processed simultaneously. (It’s valid only if the embosser of MB is turned ON.) 4. From MB_Comm Version3.7, {EPD} will be issued automatically during operation of the “Embossing File” using the USB port. 5. From Monty Version4.0, {EPD} will be issued automatically during operation of the “Embossing File” using the Serial port if the MB is selected as an embosser. June, 2009.
