Indivision AGA for A4000 Tower?

[Schoenfeld]

Hi,

with Indivision ECS in production now, there's only one machine left that cannot take advantage of a modern flickerfixer: The A4000T.

I have gotten a few requests, but nothing that would justify a production run at the moment. Space in the machine is considerably smaller, so parts of the product need to be re-designed. Features will stay exactly the same as with Indivision AGA for 1200/4000D/CD32.

I already started asking in a German forum; I'd need at least 150 pre-orders to justify a production run. If this kind of pre-order can be collected before the end of october, we might have the product under the xmas tree. Since 4000T's have been sold a lot in the US, I'm hoping for more positive results from this forum.

I already heard that 130,- EUR is almost "the hard upper limit" for the price; only a few people are willing to pay more. With the current exchange rate, that's a little over 190 USD.

Let me know what you think - and how many you'd buy!

Jens, maybe a naive suggestion, but can't you just make an adaptor raiser to use just the A4000D or A1200 version instead?

Indivision AGA sits on top of the Lisa chip, so a "riser" would have to have an empty PLCC84 chip to make connection with the flickerfixer. In addition to such a non-existent part (at least not to my knowledge), signal length would harm signal quality. I would have done that long ago, especially with so many A4000D/CD32 versions in stock, that you're hopefully buying this xmas season :-)

All Indivision models (even the external one from a few years ago) are toaster compatible. That was the whole point of me getting into this business, to make the first toaster-compatible external flickerfixer. I thought it would be obvious that I'm following up on this tradition with my updated, internal models.

One of problems of A4000T is that the Lisa/Alice are often close to accelerator.  And some accelerators are big etc.  so thats something to keep in mind.  an external flicker fixer is much safer?

External is out of the question, as Indivision depends on signals that are on the chip bus, but not on the video slot or RGB slot.

So, if accelerators are getting in the way, could you all take hi-res photos of he area? I did acquire an A4000T this week, but it's not working and has the original Commodore 040 card.

Keep those photos of installed accelerators coming! Oh wait, nobody took one yet...

Jens

[Schoenfeld]

I need photos of the accelerator(s) as they are installed in the A4000T, with Lisa visible on that same photo - ideally seen from top. Please double-check that the photo is focused, use a tripod and close the aperture as far as possible to increase focus and avoid using a flash.

I won't need a working A4000T, as the chipset behaviour will be the same as in the other AGA machines, where I have all flavours here. Development will be possible without a working A4000T; the one I own is enough for a mechanical sample. I'm happy to send a sample to someone for testing before production starts, just to play it safe, but that's far in the future right now.

I am not planning on a switch at the moment, this would make the thing even more expensive. It'll already be hard enough to reach that 129,- EUR goal with such small space available.

And yes, I will buy one.

Thanks for the fantastic material! I'll try to count some pixels to get exact measurement from the picture. Saves quite some work, thanks!

I got alot of pics for you.
You want me to email them to you?

Sure - I meant to eMail you earlier, but I've got lots of other work.
