Did you guys know about this? (http://www.c128.net/pdf/GB128_Manual.en.pdf)
more on the graphic booster
here (http://www.c128.net/pdf/GB128_Manual.en.pdf)

Finally, C=128 users could take advantage of the mega graphics software that had been languishing on the shelves.

Yes, I have heard of it. Unfortunately you would have much more luck buying a Commodore 65. This GFX enhancement is about as rare as the Holy Grail itself. I have never heard of a single unit ever being owned.

Was it probably like they would build one when it was ordered type deal maybe? I don't really see why anyone would have bought one in the first place.

You kidding me? If released today they would sell in the hundreds or thousands. AFAIK the company was tiny and didn't have funding to mass produce, IIRC they advertised but didn't sell many if any.

@redrummloa
I was talking about back then. :-P Of course, I know that today, it would be worth millions!!!! :angel:

No really......What is it ??
-
AFAIK the graphics booster just adds a few new basic commands and came with a 64kb VDC RAM upgrade as most C128s only had 16kb which is not enough for the higher resolutions. (64kb VDC upgrades can usually be found on eBay.) The C128 VDC chip is rather flexible and support interlace, so it can easily handle 640x400 and above, assuming your monitor is up to the task. (You need a monitor which can handle RGBI.)

Ahhh, now I believe we've reached the middle of this conversation!

I might be missing some thing, but it looks like it just extends basic commands. Not very differnt from a basic/asm program I wrote years ago for graphics and sprite animations tools that I used long with the 128's banked memory assests.

Again, discussion like this (about Commodore 8-bit stuff) should be moved to the "Alternative Operating Systems" forum. This is the forum for Amiga software discussion.

Correct, it has been moved.

God some people are so anal about silly things, like what forum a thread is in. Who really gives a crap

Look at the resolutions it provides. The VDC only gives 640x400 in interlace mode.

No it doesn't. The VDC can be setup to provide just about any resolution as you can freely set just about every timing aspect of it. Any VDC with 64kb RAM can do 720x700. Think of 640x400 as the pixel resolution and 720x700 as overscan if you like.

Thanks for clearing this up, I was unaware. Wouldn't anything beyond 480 vertical be outside the viewable range of NTSC?

Good question, I'm in PAL land so I don't know for sure. But maybe a CGA (or compatible) monitor required to view the RGBI signal generated by the VDC does not have PAL/NTSC issues, or the highest resolutions only work on PAL.
