Thanks Arnold. You should probably remove all my ** comments, unless 
others want to compare the original, and see what I changed, and 
why.

Nice work guys!

Thank you!

Gregg, I left the ** comments as clarification and did not spend 
a lot of time to consider if they were necessary or not. I'll have 
a look at them and clear the comments if they do not add to the flow.

Kaj, do you have specific instructions for running test apps? e.g., 
for Red/System on Windows, should all GTK stuff work, or does it 
require other installations?

Basic MS DOS Red tests ran fine here.

Hello, world!

Iirc, GTK must be installed for the GTK programs to work. It is not 
linked in.

GTK is included in the MSDOS directory. Most dependencies for Windows 
are
To get Unicode output on Windows, you need to switch the command 
prompt to Consolas font

Thanks Kaj. I will probably set up a test env for this, since I don't 
want to install all dependencies for this in my main env.

No installation is needed. The libraries are simply there and are 
used from that directory. The graphical programs can simply be clicked 
on (although they provide extra output in the command line)
Or perhaps better put, unpacking or syncing the files is the installation

Great. Thanks Kaj.

Hasn't someone written 6502 emulator for REBOL too? Was it Geomol? 
It would be nice to compare speed-wise :-)

I've never heard of it, but it would be extremely slow
I think Henrik is interested in the topic

Half a Raspberry, or run two emulators! Good progress Kaj.

I was interested as a curiosity, but probably not for my own use.

Great work Kaj! Can it be used to emulate 32-bit CPU?

6502 emulater by John Niclasen:  http://www.fys.ku.dk/~niclasen/rebol/language/em6502.r

Oh, that is indeed great comparison material :-)
Doc, it's firmly an 8-bit CPU emulator, but it can certainly serve 
as a general example to implement other emulators in Red/System
Hm, John's emulator uses RebCode, perhaps that's why it slipped my 
mind. It would be fairly fast, but only runs on some REBOL versions
It seems mostly meant for testing RebCode. It lacks a lot of functionality 
needed for emulating a real machine

Yes, my em6502.r was a test of the speed of rebcode. It was meant 
as a proof-of-concept. I never used it much. It's for the rebcode 
found in REBOL/View 1.3.50, which was the first rebcode version afaik. 
So not compatible with later rebcode.


There also is an assembler: http://www.fys.ku.dk/~niclasen/rebol/language/asm6502.r

and a MOS 6502 workbench: http://www.fys.ku.dk/~niclasen/rebol/language/m6502wb.r

, if anyone can find some use of it.

I also made a Z80 emulation using rebcode http://www.rebol.org/view-script.r?script=galaga.r

Steeve: very cool work, Galaga was one of my favorite Arcade game 
of all time, I wish you could port the Arcade version to Red someday!

Great news!! REBOL is now open source!

Kaj, thanks. 6502 brings back great memories. I got my first and 
only published program in the June 1986 Compute Gazzette with a C64 
program called Quick Key.

Wow, did that really happen? :) Could it be the beginning of something 
great?

Now we just wait for the freeing of World .. and all Rebol variants 
will be open source :)

Yay!

$ ./r3 --do 'print system/version'
2.101.0.4.4

Eh? I thought the next release would be alpha 112?
Andreas
12-Dec-2012
[1024x2]
R3 alpha 112 was 2.100.111
R3 open source is 2.101.0, at the moment.
Kaj

Oh

(Sorry, alpha 111 was 2.100.111, obviously.)

Actually, alpha 112 was never released. If it had existed, it would 
have been 2.100.112.

Carl's release numbering and naming is quite confusing
Andreas

Agreed, 2.99/2.100/2.101 certainly are.

James, I bought Compute in the eighties whenever I could lay my hands 
on it in the Netherlands :-)

And spent hours typing in listings :(
I rigged up my C64 with the speech synth module so that it would 
read out each character as i typed in the machine code listings etc
Kaj

Yeah, I think my biggest was 18KB, complete listings of the TurboBASIC 
interpreter and compiler. We haven't made any progress since then 
;-)

Thanks for putting Saphirion's efforts behind R3 Robert.
