Luckily my AudioWave hadn’t shipped yet so I could combine shipping, saves quite a bit. Very affordable piece of kit, looking forward to it to replace my original Gfx9000.

What's wrong with your original then?

The original v9990 (version 1.1?) has very bad grounding

As interesting as a v9990 light is, is there any chance a more elaborate powergraph will be released? I already have a gfx9000 but something with more features like for instance superimpose would be interesting for me...

The "Product page" link to outdated page I think. The new one is: http://www.tecnobytes.com.br/2021/04/powergraph-light-rev-2-...

The cartridge include a "real" V9990 dedicated chip or is it a emulated one (FPGA)?

I don't think that there is an FPGA implementation of the V9990....

Is the new one compatible to the first batch?
I mean, games like Intruder do they work with the new version?

FPGA or not, as long as it works well. Anyway there is little chance that the V9990 will ever be emulated by an FPGA.

Shouldn't that be something fixable?

You can add a lot of extra wires . But actually it is due to the pcb design

Yes, I recall back in the day my Gfx9000 had issues with jailbars, I went to Koen who fixed it by adding a net of wires. However because of that I feel it’s good to have a second unit.

As for superimpose, yes that’s something on my wishlist too. I originally planned to wait with buying a new one until that feature was implemented by someone. But even though there were some things said here and there, it’s not really looking to be happening anytime soon atm. Since the PowerGraph Light is nicely priced and I was able to combine shipping, I have taken the opportunity to order one .

Would be nice if that fix was documented.
@msd: Is this only the 1.1 version or the very first way too big 1.0 as well?
I have them both, but never bothered checking any of 'em... But I'd like to have them in top condition though.

I remeber bought my light two years ago. I was happy when it arrived but I had to pay fees at the custom office, which made it quit expensive. Unfornatually TMTLogic's GFXnine is not available anymore. I heard they runned out of V9990 chips...
I do own MiChis previous Video9000 but hardly use it since the smaller cards are way better to handle.

@meits: could be 1.0 doesn’t have the jail-bar issue , but it is easy to check. In a white background you can see it very clearly .

I have a version 1 of the sunrise gfx9000, from the first batch, never had any issues with it. Still works fine.

Looking at a 1.0 now. No jail bars indeed.

Is that Powergraph only for MSX II machines? Do i have an II+ then?

Sure: front, back. Doesn’t look as bad as I remembered tbh.

No, it also works with MSX1 computers. MSX2+ don't have a V9990 built in, no machine does.

That does not look scary at all. I'll have a go at that.
Thanks

Edit.
I opened mine, eager to do solder to it... To my horror it was already done

Just be sure you understand what it is for, as it is in no way an upgrade to MSX2 or 2+, it is a different VDP that only applications made specifically for it work, i.e.: you won't be using its video output on dos, basic, games that are not specific for 9990, etc (making it simple, I know there is a hacked version of basic to work with 9990 but that is far from pluging the cartridge and using its video output as a full replacement)

I knew I couldn't write a simple "10 SCREEN 25" to get the power of the V9990, but could you explain a little bit more ? Do I have to learn ASM to get it work ?

"Shipments must start 2 months after the closing of the batch which is 4 May" as reported by Technobytes.

Haven't tried it myself, but you could take a look at G-BASIC.

Ok. I understand.
I have never seen the inside of a Video9000. Looks quite complex for only superimposing.
I always thought that superimposing with V9990 was more straightforward.

Did he also add that tantalum capacitor? And if so can you read the type?
