There's a LLVM with 6502 target but lacking a stdlib AFAIR.

Re: Unixoid VIC
Still not stable enough for the console switcher.

Re: ASM502 - a new 6502 assembler.. (WIP)
You're right. There are enough assemblers nobody uses already. ;) I like it for being small and written in C. And the parsing part with expressions. What I do not like is that the code *looks* unstructured and could be readable better (after a treatment with dos2unix and "indent -kr -i4")....

Re: Unixoid VIC
The virtual console is a thing of surprising simplicity but the kernel isn't ready for it as the tests aren't thorough enough. That's why TUNIX is now a C program which suddenly decides to become a kernel. Jim Brain said that he'd bring on another stash of UltiMems, but to make them affordable about...

Re: Unixoid VIC
tunix-breakerror.png It LOADs but OPEN brings random BASIC errors out of nowhere (STATUS = 0). That's an inconvenience for BASIC coders. Time for the console switcher unless you want to do switches like this: OPEN31,31,0,"GM" (multi-tasking off) OPEN31,31,0,"PF" (fork new BASIC ...

Re: Unixoid VIC
Syscalls (via OPEN) can be nested. That's great news. Task switches work in BASIC but there's still no working LOAD but many solutions to the problem. The required boot loader won't kill any existing boot menus. As that's extra work I started the ROM in C (copies itself to RAM on startup) the Unix w...

Re: In the making: Arukanoido – an Arkanoid clone
There was more than one price to pay for that and not worth the result yet.

Re: Unixoid VIC
I have added some lines of C code in a separate file so one can see what I mean by saying "simple". That's why C was invented. What is also kinda simple is the banking – simple on paper. Some seemingly pointless doodling fixes a lot in advance. Anyway, this is getting addictive. Am trying ...

Re: Unixoid VIC
This is fun, especially with the latest VICE monitor update (build from source): vice-montior.png (I know your eyes are just having sex.) Instead of doing waiting lists for zombies implementing signals isn't much more complicated and the signal mechanism is a lot more versatile too. This needs some ...

Re: Assembler
It makes you a tough boy by over-complicating about everything? Something remotely ca65 compatible I'd find interesting.

Re: Assembler
I would start down at the metal. What's a transistor/gate. What does an adder look like. What's an ALU, data bus, address bus, control bus. Now that bits and bytes make sense, then I'd continue with assembly.

Re: Assembler
Any summary of this adventure? Somebody once asked me if I could teach him to programme. I asked "Do you know how a computer works?" "Yes! You grab the mouse *grab* and then you click here and here and…" It takes Harvard experience to teach adults like that.

First boot. Meaning userland C coding.
