I'm looking for an experienced Z80 programmer to help me make some minor fixes running on my custom Z80 hardware - which is performing measurement PAV functions like Vrms, Vpk, Vin-phase ratios, fundamental etc. The first task is to resurrect our assembler-complier and create a hex file - identical to the version already have, if these stars align, then its a good start. Next task is to ensure the interface switch (menu item), can be fixed so Serial USB (Max232 driver UM232) or GPIB IEEE.488 can be selected. There is a menu option, presently it does not change the selected interface work (but it did work!). Key Requirements: - Extensive experience with Z80 assembly language - Organised approach - Prior work with debugging embedded systems - Ability to understand and interpret detailed technical documentation and schematics I can provide comprehensive documentation about the hardware and the software. Please include your experience with Z80 and embedded systems in your bid.

Hello, I understand your need for an experienced Z80 programmer to address specific debugging tasks on your custom hardware. Given my extensive experience with Z80 assembly language and embedded system debugging, I'm confident I can assist you. I'll first work on revitalizing your assembler-compiler to generate a hex file identical to your existing version. If this aligns well, I will then focus on resolving the menu interface issue, ensuring the Serial USB or GPIB selection functions correctly. I value a structured approach and am skilled at navigating detailed technical documents and schematics. Could you share more about how the interface switch initially functioned and any changes that may have occurred since? Looking forward to collaborating with you. Regards, Muhammad Awais

As an experienced full-stack developer, I bring a unique set of skills to the table for your Z80 code debugging project. While my main focus has been on software development, I have a knack for problem-solving that translates across languages and platforms. Over my 10+ years in the industry, I've mastered multiple languages including C# and Python – understanding the nitty-gritty of code is second nature to me. The fact that you need an organised approach is right up my alley. My proficiency in using Git tools like GitHub and GitLab along with my experience in Agile methodologies ensures project management and tracking would be smooth, streamlined, and efficient. I'm equally comfortable working with both classic and modern frameworks like .Net and Angular respectively – versatility that can play well in a task involving ASSEMBLER and GPIB IEEE.488 interface selection. My commitment to the customer journey coupled with my track record of successfully leading teams through complex projects provides a guarantee that not only will your Z80 code be debugged effectively, but your hardware-software interface will also be optimized. I look forward to applying my detail-oriented mindset, deep problem-solving expertise, and strong project management skills to breathe new life into your assembler-compiler and ensure the right interfaces are working as intended. Together, we can bring fresh life to your custom Z80 hardware!

With my comprehensive understanding of multiple programming languages and my extensive experience with embedded systems like the Z80, I believe I am the ideal candidate to tackle your project. I've successfully completed numerous projects related to computer vision, speech/audio processing, web scraping, and automation - all which utilized my skills in precision, attention-to-detail, and thoroughness - qualities that are absolutely necessary for debugging. Throughout my career, I've developed a strong proficiency in not just dealing with complex software issues but also in interpreting schematics and technical documentation. This becomes especially crucial when working with custom hardware like you have. Further, I've been entrusted with tasks where it's imperative to create similar hex files of original versions which have only added to my careful approach in my work. Another important aspect of your project is fixing the interface switch/menu item. With Garcin plot implementation using GPIB IEEE-488 protocol, even though the system utilizes Max232 driver UM232, shouldn’t be a problem as I'm trained and competent in a wide range of interface and protocol technologies. Partnering with me on this project ensures not just a smooth continuation of your work but also an expert who's strongly committed to exceeding client expectations - every single time!
