    Intel 8085 question

    After a quick look I came to the conclusion that it would take a lot of work, problem is the 'windows forms base' of the program as it is now. Also converting to UWP or WPF would't be a solution. Checked Mono as a possibility but there are many snags with that I'm afraid. So I'm not porting the...

    Intel 8085 question

    Indeed it is the question of what a simulator is. In this case it just simulates the input/output of the SDK-85 in the form of a display and keyboard. So nothing with the timing (which is considerably slower with this program for the purpose of examining the assembler code running on it). I...

    Intel 8085 question

    It emulates the SDK-85 in the way that is displays what is send to memory address 1800H and it reads the keyboard (if you click with the mouse on a button) by filling that value in 1800H. But only if interrupt 5.5 is enabled (not masked) because that is the interrupt the SDK-85 uses for the...

    Intel 8085 question

    Now at version 1.3 of the simulator, fixed some bugs. Thinking about adding a second display/keyboard form for debugging other homemade (single board) systems, maybe based on a multiplexed system (port for digit, data for segments). Any thoughts ?

    Intel 8085 question

    Will have a look at that document, thanks. Still working on restoring my 'real' SDK-85, when that has finished I can check the simulator against the real thing.

    Intel 8085 question

    Please do and give your findings about it. Just noticed I have to check on the undocumented instructions this weekend, ARHL was incorrectly interpreted.

    Intel 8085 question

    Just my 2cents: Recently acquired an SDK-85, so busy on a simulator for it last few months. Just uploaded the first version to GitHub for those interested: https://github.com/ForNextSoftwareDevelopment/8085

    Internal Stack Overflow

    Hi all, I recently bought me an IBM 5160 that I was able to put to use after a low-level format of the harddisk and installing MS-DOS 3.3 on it. However, I noticed an 'Internal Stack Overflow' after operations for some time. At first I suspected the keyboard (interrupt) because of the...
