I just would like to help to make some small conversions and editing some out/in data in some ROM files. Very simple and shouldn't take much time for someone that at least has a partial knowledge of Z80 assembly.

I would like to create some simple programs for an old computer standard using the Zilog Z80 CPU. The person working with this project has to have a good knowledge of Z80 assembly and architecture.

Need a skillfull person who can help me to change some mapper changes within a bunch of ROM files. Needs to be familiar with Z80 micro computers.

I have a project I would like to have finished at minimal cost. I have already written quite well, the VB5 / VB6 parser which can use pluggable code generators (Z80 source code and java source code). It supports close to 90% of the language to allow Z80 development or Java development within the VB5 or VB6 environment (can test in there first and later via a plugin probably cross compile from thee too). What's done: parsing of the VB project files, the modules and the classes to create an intermediate XML file. (I don't need forms to be parsed, or generated - the intension is that a library will be written within VB to simulate a Z80 or Java target and an equivalent library written in the target to have similar video output). The intermedia...

...read the counter value while the counter is still in the process of counting, one must first issue a latch control word, and then issue another control word that indicates the order of the bytes to be read. An alternative method of obtaining a stable count from the timer is to externally inhibit counting while the register is being read. To this, an external logic to the 8253 controlled by the Z80 to inhibit count during an input read operation is to connect. Each technique has certain disadvantages. The first, the latching method, may give the CPU a reading that is "old" by several cycles, depending on the speed of the count and which byte of the counter is being read. The second method, the external inhibiting function, requires additional hardware. In addition, it...

I'm looking for someone to finish a project that was started but then we lost contact with the programmer (so we have some of the deliverables close to completed). The project is to make a math program for me for Texas Instruments calculators. The program would have to be made in z80 asm (there is very good documentation from Ti, and it is calculator programming and mostly simple math so I'm assuming it won't be extremely difficult to learn). The program would be created and compiled using Ti's software development kit located at: I'd actually need 2 different programs - one for the Ti-83 plus/84 plus calculators, and one for the Ti-89 calculator. The bulk of the programs would be a conversion of about 9

Project will require the ASM/Z80 programmer to code for the TI-83 Plus calculator. This project is not a game, nor is this project an application. The project is a secruity suite.

Requirements At the recent British Indoor Rowing Championships, twenty men contested the Open Heavyweight competition. The race takes place over the standard distance of 2000 metres and the time is recorded as each competitor passes 500, 1000, 1500 and 2000 metres. The winner is the rower that completes the 2000 metres in the fastest time. There is a further prize for the rower that completes any intermediate 500 metre segment of the race in the fastest time. The data for the results of the race is stored in the file "". This data file is available for testing your programs from the following link: [][1] Your program should: * define appropriate user-defined data types (enumerations and/or structs) to model the data of the application. * read the race data from ...

...record has the same length, and we can specify the size of each field. Commas and quotation marks would have to be removed, and the fields padded with zero bytes. 2. We then need a function which will perform a binary search of this file for a specified string in the first field. The records will be ordered by the content of the first field. If a match was found the record would be returned to the Z80, otherwise we would nees facilty to insert a new record positioned to keep the records in order. The buffer 4 size could be reduced to 1024bytes but it may be that we still needan extra 8K for the code! In the CSV file each record (line) has a different length because the amount of text in any field varies from line to line and there are no padding characters. It is much easier ...

hi all! I'd like some help with Assembly for 8085 (not z80,not others). My hw is multiplication and division for signed and unsigned numbers, 8 and 16 bit. Total 8 programs (unsigned mult 8bit,unsigned mult 16bit,signed mult 8bit,signed mult 16bit, same goes for division). The signed mult using Booth's algorithm (preferable). I got the algorithms+flowcharts for all (i have understood all and think they are ok) and i have written the source code for all but only the 2 first programs work ok:( The compiling and simulation is done with 8085 simulator (freeware can be found here: ~amanb/ ). So, can anyone correct them so they work ok with this simulator? Explanation on hard parts or when using different algorithm than provided would be nice but not absolutely
