yes! Is it yours, and was I giving you a hard time?

Especially if you read the name as an acronym

Yes, it's mine, and no, you weren't giving me that hard of a time. You at least did find two bugs in the assembler.

@spc476, thank you again for the assembler. I like it more than a couple of others I tried.
What kind of a 6809 system do you have? Are you working on anything interesting?

I have a Tandy Color Computer in storage, so I tend to use either the 6809 emulator I wrote (which is also part of the assembler), or XRoar, a Color Computer emulator.
Besides the assembler, I too, am currently working on a 6809 ANS Forth system, which started out as me trying to figure out how DOES> is implemented.

Excellent. If you ever want to put together a 40Mhz 6809 on that $30 board, I'll be happy to assist.
Original Post
Forth Advanced Run-Time — I've been coding in assembly on a Forth-friendly 6809 system I slapped together on the $30 Tang Nano 20K FPGA board. I always wanted to try a 6809, mainly because it has a User Stack that works perfectly as a Forth Datastack -- complete with push and pull instructions. Unlike all other processors out there. Well, the 68K allowed any address register to be used as a datastack, I suppose. But the U register is actually designed for Forth. Anyway, I wrote a bootloader,...
