Oh yea! We changed it. Thanks Aaron.
ba ha ha this has been a gold effort by all thank u for ur help and ya all get a pink elephant sticker for trying :) cheers once again
:)
omfg its nt working now im gonna cry again lol i keep gettin so excited at the chance of a link and then it doesnt work lol sorta like the year 2oo0 that sucked lol

Sorry about moving files around, I think someone put this on the FTP also but here is a link to the copy I have. Still looking at old hard drives. I know I have a few versions of this software.
Hi everyone, I'm new here!
I've been interested in lasers and building a DIY scanner for years and finally go round to it. I'm also getting back into FPGA development and want to join the two projects together and control the analog Galvo drivers and TTL laser modulation using the FPGA (via two high speed DACs to drive the galvo drivers).
I then thought, why not implement some old vector graphics game using the scanner? Then I did some googling and found someone has beaten me to it! LaserMAME, how cool is that?!!
Anyway, just thought I'de post to see if anyone is still interested in this. I might even be able to program the FPGA to run the original (or a re-implimentation close to the original) arcade machine hardware, i.e. emulate an old vector acrade hardware in the FPGA along with a custom display driver to display using the laser galvo scanners and TTL modulation.
Once I have something working I'll post some pictures :)
i strongly recommend analog modulation over TTL. with TTL, you'll have a maximum palette of only 7 colors and no control for fading or color cycling.
the big trick is not in emulating the original hardware quickly enough, it's dynamically controlling scanning display optimization so the output can be scanned without being too flickery. this wasn't a problem with electron beams and phosphor screens, but when you start wiggling mirrors and depending on persistence of vision, it gets complex.
there's a forum user called "zoof" who wrote a really incredible asteroids clone called "laseroids". he might be a good source for information on handling scanning optimization.

Thanks! I thought I would probably be biting off more than I could chew. I did think about analog modulation, but as this is my first attempt, and didn't want to spend thousands on hardware or have to build much hardware myself, TTL seemed fine for a first try. Although I agree, proper analog modulation and a 40/60k scanner would be nice :)
I'll certainly try to contact Zoof, his asteroids clone looks ace! I didn't think that the persistence of vision would be too much of a problem, but then with a 20k scanner I'm not looking to draw that much complexity, just a few sprites (vectors) in a few colours should be enough to play with to get something cool working :)
Thanks again for the quick reply, this seems like a great community :)
