I have lots of z80, 68k, 68x09, 63c09 etc that I would love to understand more deeply how they actually works in the boards that they are used
.
I need to get me a proper DosBox setup so I can run all these old softwares. I dont have any old PCs left at home really so I guess dosbox is the best (only) choice
Ideally thou would be win software with gui for ease of use when handling assembler (as a total newb).... but might not exist for 6801u4 and such?
That's a tall order. I'm sure there are GUI's or editors that could be massaged into doing this, but you'd end up having to figure out all the command lines needed anyway. I think it's better to just use an editor you like (I use Notepad++) and create some batch files for the build process. I'd be happy to learn of a better way though. I use PlatformIO and Visual Studio Code for a few things but that's just more stuff to learn. For assembler my method is fine. I used Win7 and newer exclusively but I have access to XP and older ... but I can't really recall needing them in a long time.\
Could I please have the dissassembled file?
I thought that if I went throu it and commented all whats happening then I might actually learn a thing or two when looking up all instructions and operands.
I think I would have lots of use of learning assembler in my hobby actually.. then it would allow me to write own test code for certain games to test out memory and such on the pcbs I am repairing
I did look for a schematic for this game. There was one for a Z80, but nothing for the 01. I have no problem giving you the disassembled code but would be doing you a disservice at this stage. If I can locate the schematics, I could possibly start to comment some of it for you. To be honest, even with my skills and knowledge of the 01, without an understanding of the hardware, trying to understand this code would not be trivial.

Found it. Still even with this, the project would be a significant amount of effort.

I suggest you focus on marking up the schematics and getting them posted. Then get the hardware built. Once that is working, you can worry about things like DOSBOX and tools.
I am not aware of any GUI based tools for the 01.
Thinking ahead, there are two books Motorola put out that I recommend you try and find. The first is M68HASLK/D1. This is the book for the tool set. It's fairly thick. It doesn't cover the instructions or how to code in assembler. It's strictly for the tools (command line options, coding syntax, ... ).
The other is MC6801RM(AD2) which is specific to the 6801. It contains a fair bit of detail about the hardware and how to program the device.
I have a few other books but these two are really the only ones I used.

Phew, back in the game.. my main HDD died on me and since it was quite old pc overall I decided to build myself a new. Fortunately I had backups of everything but its allways a hassle with reinstalls and upgraded to win10 this time.
Anyway, I cant for the life of me find the systems book (the M68HASLK/D1). Any ISBN number printed on the back of that book?
The other I have found so far..
There is no ISBN number. Like databooks, these were distributed by the reps. Maybe eBay, Amazon or used book stores. There is another booklet they published on how to use their BBS. In there you will find a directory of all the files they had available. This is where I pulled the tools from. They may have had this document on-line in some plain text format.
That book does seem rather rare, however there are other books on the same topic (like, ISBN books incl text books) as well as the data books and applications books from that era. Lots of assemblers too. I like the Baldwin AS68xx stuff. Main problem with assembly language is that various assemblers have slightly different syntax so sometimes you need to tweak things as you go from one to another.
Here is the Baldwin as68xx stuff. He's been keeping it up since who knows when :
http://shop-pdp.net/ashtml/asxxxx.phpThere may be others that are closer to the original, ... I bet there are dozens out there.
I realise that this is a very late reply but I have a copy of the Motorola application note AN906A "Self-Programming the MC68701 and the MC68701U4"
As this doesn't seem to be available elsewhere I have attached a scanned copy.
bytestorm if you are still checking this thread I hope this is useful for you.

Wow, you really had this and scanned it for me? THANK YOU!
I am still checking this thread.. I have since last time finally gotten the chips programmed by a guy in france, since I just couldnt seem to ever get it done myself
Too many hurdles and I just lost the patience..
That said, now I have the new schematics, thanks to you, so lets build this thing!
Ill keep you posted! (If enyone else checks this anymore)
Here is the schematic. I had to make some changes to the 21VDC supply since I couldnt find that typical module.
I also choose bigger eproms since the old ones are getting more expensive and harder to find..
Please let me know your thoughts!
The changes look fine. The switching regulator is more than capable and the larger eproms are not an issue.
It is hard to tell from your schematic but are you aware that the +5V to the left of SW1 is the input and all the other+5V on the circuit should
connect to the right hand side of SW1?
Excuse me if this is a dumb question.

Well spotted. I didnt see that actually
. Now, of course the MT3806 is nowhere to be found so I might need to take some other part instead for the step-up :/.. onsemi.com might have some..
MT3806 is actually availible on some kind of module already assembled on ebay.. but I am not a fan of having to rely on another module to fit the pcb :S
You could try the MC34063. It is available from a number of manufacturers and is quite common.
Most car chargers for mobile phones will contain one or an equivalent.

Yeah that one seems better. And has some tutorials also on how to calculate all the correct parameters for choosing the components! I will rewamp the schematic for that one
. Thanks!
