Oooooohhhhhyeaaaaahhhh...

Happy new year.

However, I am mindful of an old adage which says just because you can do something doesn’t mean you should do it.
And you would be absolutely in the right. :|

I'm torn on this. I don't NEED this. I just wanted to do it, because I thought it would be cool to have. I have already started ...

In CELL, and CELL only. The size of a cell on stack CHANGES with a new value in CELL. All the routines that deal with cells adapt to it.

dawnFORTH uses a truly variable cell size stack. That means that all calculations necessary to access cells are revolving around what's in CELL. You can pretty much arbitrarily change cell size to be, say, five bytes by just executing:

5 CELL C!

All other operations will follow this new size ...

I'm starting to question my life choices...

Well, not really... ;)
I'm continuing reading Garth's treatise on stacks, and it is really an eye-opener. I specifically like his structured approach to assembly programming with macros. As soon as I've figured out how to do this with vasm I will try it ...

Ok, I'm going to take a risk.

Right now my data stack resides right below the top-of-memory. It grows downward towards HERE. As long as these don't collide everyone's happy. That's a BIG data stack...

Do I really need it?

I already made some changes to my code (this hasn't been uploaded yet!) so ...

More bug fixes. Please re-download.
- Fixed... annoyance in "ACCEPT", where ACCEPT would use the input buffer pointer instead of a temporary one, leading to the input buffer pointer (thus SOURCE) being overwritten and subsequent input getting stored into whatever buffer address you provided to ...

Small update to "system.fth".

Hi, folks.

Since I (politely) got told to not help junking up the introductions thread, I'm more than happy to oblige and start a new discussion here:

Have you seen hardware (and maybe even have pictures of it) that under the circumstances you've witnessed it should NOT be able to operate, but ...

Yeah, public playing is probably not a good idea for me. I haven't practiced in a while... Well, they're right next to my computer. So I just need to pick them up and play. ;)

I really didn't know that the 6502 is still being used that often. But it makes sense. It's simple, it's hardy, and it's ...

I hear you, Neil... I hear you. Belated welcome to Germany. It's not perfect, by any means, but it's home. I hope it can be your home as well.

It's still 2025, so I can still congratulate the 6502 and Chuck Peddle (RIP) for 50 years of awesome service. May you still be available for another 50 years and teach the young'uns how it's done. Learn the basics, then upgrade from a solid knowledge.

NOTHING beats the awesome images of a Cray main-frame. To me, this is still the pinnacle of "Big Iron".

Well. Who am I?
I was born at the dawn of the '60s. You know, Cold War, My Generation, student protests against the Vietnam war, oppression, the burgeoning "green" movement, The Rolling Stones, The Beatles, The Who, The Pink Floyd and all of those ...

That... is ancient (the youngster would say about seeing a Windows XP screenshot). ;)

I remember my first contact with a computer was a PDP-somethingsomething (PDP-8?) in somewhat 1977/8 during my first year at the "Technische Gymnasium" in the city of Mainz/Germany. This ONE meeting kindled my ...
