Just published the TK-85 simulator on Github: https://github.com/ForNextSoftwareDevelopment/TK-85 It also contains the monitor source code.

With this listing I can make an effort. The scanned pages of the manual would help as well since I could not find a (pdf) copy of the manual. Since you're a linux user, is this project of help since you couldn't run it on a linux computer ? (tho wine comes a long way). I will look into it and...

Looks like a nice project but without the proper rom listing (with labels and comment) it would be a very hard job to do. However, my project for the SDK-85 is open source so if you want you could give it a try ;-)

Also have the multi application board. Seems to be for both the MPF-1 and FLT-68K. Just made a connection cable for it and it will be fun to play with it as soon as I have mastered the board itself ;-) Best regards, Dirk.

It's alive :)

Send a mail to flite ( https://www.flite.co.uk ) to ask them if the still have manuals. Waiting for a reply. mvg, Dirk.

Also obtained one today (serial 20081, without a manual). Searched for it online, but no luck. Anybody obtained a manual by now ? mvg, Dirk.

Hi All, I recently made a BIOS program for the RC2014 system and created an assembler/debugger to develop this. This BIOS is for running CP/M on the system (which was already done before but for educational purposes it was fun to make my own). The assembler/debugger makes use of a terminal...

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...

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...

Since c# is now available under linux I will give it a try coming days.

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...

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 ?

The Op8085 is new to me, thanks, will come in handy :) Already made some improvements, now at version 1.1, also added a changelog to the repository.

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.

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

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

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...
