I have a monitor for my ‘02 three chip boards that could be used as a starting point but I don’t have an ‘02 or ‘134 SXB to develop or test on.

Jup, that 16->8bit convert is going to take a heap more time then i anticipated..
Your monitor for the 3chip, is that https://github.com/andrew-jacobs ...

That would come in handy, thx..

i'll see if i can make the sxb-hacker work on my 02sxb board (no promises)

The '02SXB and '816SXB are designed to be used with the WDC tools. The firmware on these boards talks a binary protocol used by the debugger application. Its not a full monitor.
...
WDC wrote a document for each board that contains details of the hardware (but not the debugger firmware)

That ...

Yup... i started there, but that example project is not available anymore..

WDC Documentation on the w65c02sxb is scarce.
the one's that they have does not give me Anny good info
on how and what.

same goes for subroutines and in depth info on the board.
but that is part of the fun, figuring out ...

what about RTS/CTS ?

Nope does not work either..

I'm under the impression that there is no mensch monitor on the w65c02sxb.
and that you have to run or connect to it through the wdcdc (debugger)
but the debugger is doggy.. it give me adresses like 00:8000 instead of the 8000
the scroll button of ...

Hi,

i'm trying to connect my 02sxb board to the computer (usb)
the most basic thing you need to getting started.

it does connect (Connected to SXB at 9600 baud) , but then it all ends...
no Mensch Monitor.
i used easySXB and Putty.. no luck on both (same behavior)
tried COM1, COM3.. no go

but it ...

When the ROM initialises it can disable the monitor and expose its own set of interrupt vectors at the top on memory.

The '02 and '816 SXBs have WDC debugger code in thier flash ROMs which you MUST NOT erase if you don't have some way of programming the flash chips directly.

Thx, but if you ...

Hi,

I read the flash-guide from scotws and andrew-jackobs, ( https://github.com/scotws/265SXB-Guide/blob/master/flash.md )
and understand that when connecting FA15 and/or FAMS pins on J3(P4x) to GRND (P42) is controlling the
way your SXB board is booting up.
2 pins, 4 options (00,01,10,11) each for ...

in my understanding, there is no "JSL" in 8 bit.
does "JSR" do the trick, and do i leave the 00 from $00:e04e (put_str) ? JSR does indeed do the trick! But although the W65C265 Monitor ROM Reference Manual does mention put_str , the W65C134 Monitor ROM Reference Manual does not. However there is a ...

Hello,

i was trying to get text down the uart3 line, and tried this http://forum.6502.org/viewtopic.php?f=4&t=3545#p42268

thing is, you need to "JSL put_str" the thing...

2 questions:

how can you do this in 6502 emulation mode ?
and how does this work, when you have a 134sxb (8bit) ?

in my ...

Thx man.. that's the one..!

all works now..

still hard to figure out what to use at the beginning if you start a program.
setting 8/16 bits, native or emulation.. sep/rep, longi, longa, chip ect ect...
good thing there is nice documentation here at 6502.org ....

all restarts are hard in the ...

Hi all, after a long time i decided to pull out my w65c265sxb board again.

i started with the 'led blink' from http://www.mikekohn.net/micro/modern_6502.php .
follow directives, used the naken_asm compiler... and yes result, it works.

not a real fan of the "new" code style from naken_asm
so i ...

Which version of TIDE are you using? There's at least two different ones out there.... I'm using Win7 in a VM under Fusion with TIDE version 2.05.0. Granted, TIDE is not that great of a front end, but for what I use of it, it works for me. I also have version 2.04.3 which works under Win7.

Hi ...

Hi all,

i've got a real difficult time making TIDE from wdctools run on W10.
it gives me error's of missing symbol file, the (text) editor shows no file content ect ect... (uedit and notepas++)

so basicly , what can i use as a good alternative to program in, and to upload it to my w65c265sxb ...

The timing constraints are well inside that of a 6502 - the shortest time you need to pulse the line low for is in the order of 6µS.
[...] also are the I/O ports protected or can they handle a bit bang ? (output a bit/pulse, while a bit/pulse is coming in)
if i shorten them because the timing is ...
