Dear Daryl,

Thanks, it works.
I have another question. Is there an 6502 monitor (simple) that runs on the emulator.
I am verry interested in this, for my esp32 emulator project. Running 6502 code on my emulator is working, but I missing a small monitor. When this works I wont to implement ithis on ...

Thanks, nice work.
Have played with it, but one thing is not going well.
When starting fresh with FF00R the program is hanging.
And always when I send FF00R the program hangs.

Please can you take a look.

Cheers,

Jan

Dear Daryl,

Please can you post the asm code for me.

Cheers,

Jan

Dear Daryl,

The testfile is working perfect, de wozmonitor all most.
After setting my keyboard to uppercase it was running.

But try to run this simple test program scrolling text on the screen :

0000: A9 00 AA 20 EF FF E8 8A
0008: 4C 02 00

but without results. Run it on my Replica-1 SBC and it ...

Thanks for the quick respons.
Have set the IO at $D000, compile the code and switch to the debugger.
The IO window is popping up.
Push RST and run in debugger. Notting is comming up in the io window!

Do I sommething wring? Use the latest version of the emulator.

Cheers,

Jan

I wont to run the woz-monitor in the simulator. But what I trie no succes. Can someone help me out with this, perhaps a running version is very helpful. I struggle withe the in- and output of the simulator in respect to the woz-monitor.

Thanks for any help.

I have not looked deeper into the woz code for some times, but I compiled a small test program with vbcc using the woz library and checked a few of your steps.
Hopefully that helps a bit?
Nope, it doesn't. It helps a lot :D

I think what is apparent is that I need to understand the FP format ...

Could this be a word printing the return stack, because first is printing the stack contence!

It’s came from:

I found in the FD-V05N1.PDF an intersting article “Add a Breapoint Tool”. (Leo Brodie)
There was one word I could not find back.

“N.R”

What is the meaning of this word?

Cheers,

Jan

Problem is solved, have placed the variable in the beginning ( first two declarations )in to the wrong order.
Place them under the varable definitions and all is compile well

When I compile the source got a strange message,
ERROR E022: Phase error-inconsistent label value between phases "SINOVF" ....
The code is straight from a rom listing.

Is this an error of the compiler?

This is my code.

Thanks for any help.



ROMBASE =$D800 ;STARTING ADDRESS OF F.P. ROM

Knows someone the definition (source) of the word marker?

Writing the D2* and D2/ as primitives will make them extremely fast compared to using the division and multiplication routines.

For D2/ :
LDA 1,X ; Get the highest byte and
ASL A ; shift left (to preserve the sign)
ROR 1,X
ROR 0,X
ROR 3,X
ROR 2,X
JMP NEXT

For D2* :
ASL 2,X ; Start with ...

Only lightly tested. Do you need 2@ and 2! as well?
: 2CONSTANT <BUILDS , , DOES> dup 2 + @ swap @ ;
: 2VARIABLE <BUILDS 0 , 0 , DOES> ;

( These next two would be better as CODE words but )
( FIG doesn't have the assembler loaded by default. )
