Hi guys!

How work the interlaced resolutions under indivision aga?

What is the bug connecting indivision aga in a HP or C= Liisa?

Exist some kind of issues by hot having the a1200 turn on some hours?

Thanks a lot.

Interlaced is now rock solid.

That bus has not mansifested itself on my machine yet.

No issues as I replaced my Al200 MB as it was acting wierd (garbled graphics and lockups)

Interlaced seems fine and rock solid as another user had posted.

I experienced problems with long term use BEFORE I installed a tiny fan on top of the case. A 12v fan with rubber bumpers is all I am using - that sucks the air from, through and out of, the A1200's case (sitting on top of the vents, above where the AGA card resides). Not sure if the Indivision product (like most electronics) require a "break-in" time, but all seems good now. Am going to continue using the fan as I'd like to avoid an overheating scenario if I can help it.

It does seem that users of HP Lisa's are having, or have had, problems with seating the Indivision board *AND* potential other software incompatibilities.

All seems fine now and am enjoying my Miggy as I haven't in years.

Utilising Hi-Res Workbench screens for the 1st time outside of an Amiga with a 1084 (ie: aWeb, iBrowse, NewsRog) has me wanting a real video accelerator however :-) Same goes with the prospect of upgrading from the current processor I have (an 030).

All in all, breathing new life into an A1200 outfitted with the Indivision AGA card... would LOVE to expand it even further to be a more formidable machine.

Guess I'd like to explore this SAM/4.1 option I keep hearing about :-)

Bottom line Re: Indivision AGA - you cannot go wrong. Especially for games. This is a top notch, Class A, well thought out product that is worth every penny of its asking price.

They all work very well.

There are apparently 3 different Lisa chips all of different heights. There are only issues with the lowest chip, if you have such a chip you can always sand-down the connector to get the correct fit.

No kind of issues exist for this.

Just make sure you flash to the latest version of the firmware and that you also use the latest version of HighGFX (which allows rock-solid 1024x768 and a 1280x720 widescreen mode :-D ).

Incorrect - I *have* experienced problems with Indivision being on too long. Before the fan, graphics would become garbled. Sprites/icons/scanlines would flicker, etc. And my machine, which has a modest accelerator card/ram, has an A500 power supply feeding it - so it's not like there is a real power drain going on in my system...

And *YES* - HighGFX rocks. Great little patch that I have been using w/ ZERO issues since the 1.2 firmware (and my fan installation) was made available.

Wow! Highgfx sounds really cool, these resolutions on a1200 tahts cool.

My experiences with other flikerfixers on my own arent too good, corrupted icons, secreens, fail of syncs and hot as hell, but indivision seems like perfect one.

If i purchase one will mounted in a1200 on my old mikronik tower with AT psu hope that be a good solution for power issue.

I'd like to get one myself, but I hear that the Indivision AGA is incompatible with the Elbox FastATA-III Controller IDE accelerator, which really cuts down on CD burn time for me. Is this incompatibility true?

kickstart · « **Reply #7 on:** October 24, 2008, 03:26:47 AM »

I think thats not possible, elbox fastata occuped part of the place for indivision aga in the a1200 motherboard, maybe with a overdimensioned connector to the Lisa chip...

Im thinkin just in how to mount it between idefix express.

PD: Edited for some errors

No I think the issue is with FastATA + Mediator + IndivsionAGA

The issue is with FastATA and Indi as part of the indi's board occupies the same area as the FastATA. When I had a FastATA, I fixed it with ROM spacer kit which lifts the FastATA up. However, if you have a mediator, this will then give you problems due to the increased height of the FastATA.

One more stupid question about it... in a lcd or tft monitor, how good is showed in a non native monitor resolution?

tone007 · « **Reply #11 on:** October 29, 2008, 09:35:06 PM »

That depends on the TFT/LCD, some scale better than others. Indivision can't make them do any better than they would connected to a PC.

It also depends on the aspect ratio, an older 4:3 TFT will always look better than (scaled) 16:9 for games (WB is ok because HighGFX now supports a widescreen monitor driver :-D ). Another option is to run on a widescreen monitor with black borders to maintain the correct ratio.

You might also have trouble running games at low 50hz (needed for smoother scrolling) with some TFT's (works fine on my brand new Dell LCD monitor though!).

HighGFX modes are very usable in 4-16 colors on my A1200 with 060 @ 50 MHz, almost feels as fast as my A2000 with 030 and Picasso 2 feels like in 16-bit 1024x768

I dont think you need to cool down the scandoubler since it is using lower voltage parts, in comparison with my previous DCE-scandoubler that I tuned with a heatsink the Indivision runs a lot cooler.

Yes that DCE-scandoubler was actually too hot to touch so the heatsink was not a show-off thing, however it worked excellent with and without heatsink

@tone007

Yes i know some tft-lcd scale better than other but all of this is much present in wb or 2D games than 3D games full of polygons and textures.

@novacoder

I dont know the specs of my tft that i want to use with amiga is 4:3 more than 3ms i think but native resolution is 1280x1024 too high for aga.

@cv643d

I have a dce scanddoubler with flickerfixer now and is hot than hell and very noisy images sometimes (at least mine).
