It's in quite a few files so that someone who doesn't want the extensions for math or prioritized interrupts & alarms or time & date functions or assembler for example could leave them out simply by commenting out the relevant INCL lines (one for each file you want to leave out). I never tried a minimum version to see. The whole thing is about 24K IIRC, so maybe the minium would be about half of that. It is rather complete though, with oodles of functions I never saw in free versions. Wally Daniels (a forum member we have not heard from in a long time) used it in his work in the Pratt & Whitney turbine-engine plant in Nova Scotia, using a 65265 '816-based µC. I should ask him how much ROM space he used. I did the '816 Forth in a rather dead time of my work in the 1990's and I know it has been a disservice to the community to not finish cleaning it up to publish, but now that I have a website it's on my list of things to do. I also want to make the few changes needed for a RAM version, and then do the equivalent for my 65c02 Forth but that will take even more time, for a few reasons.


Yes, and actually I seldom have any reason to run the assembler on the PC anymore. When I do, I can send the hex file over the RS-232 line to the workbench computer. Otherwise I normally send source code over the line to the workbench computer which then compiles, assembles, or interprets it on the fly, as appropriate, which gives the option to try just a line or a routine at a time with instant turnaround instead of having to re-assemble the whole application every time you make a small change.

Happy to report a success - I added a binary load command to Daryl's monitor and loaded my first program!

Many thanks for all the help to everyone, especially Daryl.

My 6502 skills are rusty, but I think it's correct.

I think you might have a problem with any count of the form 'xx00'. If I understand the code correctly, counts with a low byte of zero will try to read an extra 256 bytes.

Here's another crack at it:



I cannot believe how many times I had to test $0000, $0001, and $0100 before I got this to come out right (I think!).

I was having a hard time with it, and am not too surprised I missed a case. Since the carry flag is not set by the 'dec' instruction, counting down is surprisingly tricky. 'inc' works out ok - when low byte is 0 we want to increment the high byte...

As I want to have a monitor program in my 65C02 SBC I wonder if this thread is still valid.
I would like to habe a simple monitor program like the WOZ Monitor which allows me to send Hex values to address in RAm and start a program.

All topics are valid indefinitely. Projects here may go for many years in their improvements and refinements, if not the original build itself. Some people think that just because it's old, they have to start a new one about the same thing. It's better to keep it all in one place. Also, the most appropriate people, those who posted in the same topic before, will get email notifications that you replied, if you keep it all in the same place.

We have a couple of registers available, why not use them? And we can complement the count to shave some cycles (untested):
