Title: Official Scandoubler
Post by: fondpondforever on January 28, 2015, 01:50:46 PM
Is this the Official Scandoubler made by Commodore International, Amiga Technologies or by a modern company? Saw this on eBay and thought this looked fascinating. :p

It's not official, it's home made.

It's the GBS8200 in a plastic box.

If I print out a Commodore logo and stick it on my toaster, does that make it an official Toaster?  :lol:

The only Commodora built scandoubler, as far as I know, was the A2320 card.

This thing you linked is just some homebrew thing based on the GB stuff.

Save your pennies and just buy an Indivision, it's easier.

Says in the blurb "Original idea born over 2 years ago, now professionally designed and assembled"
So something new, certainly not Commodore or Amiga Technologies.

Tons of people.  Do a forum search for GBS8200.

IMHO they suck and are a lot more trouble than they're worth.  Just spend your money on an Indivision.  But I guess an external device could be useful for people who have a bunch of Amiga's and other older devices (Commodore 64's, game machines, etc.) that they want to hook up to a modern monitor.

I can't say it was the same revision, but I purchased one of these. It worked, however, there was a small bubble around the cursor that distored things around it when moved over icons etc..  The bubble wasn't visible until it was moved over something. Maybe things have been improved with this latest revision.  I went back to using a CRT.  Although I do want to get an Indivision.

I've read somewhere (can't remember where) that some boxed versions of the GBS8200 for the Amiga (quite possibly this one) power the unit from the voltage pins provided by the Amiga RGB connector, however the current draw is greater than that recommended by the Amiga specs so it could cause damage to the Amiga. So it's worth checking first.

You CAN power this device and others (like genlocks) from the pins on the RGB but its better/safer to use external..

Make your own case, buttons and equip it with an LED with this board installed then you have the official Commodore Scandoubler. WOW i want one of these :p

Or just spend the cash on an Indivision, which works better than any of the other flickerfixers anyways.  Other than the various RTG boards, of course, which offer far more than a simple flickerfixer/scandoubler.

Why would you want to put an A2320 into an external case with blingy blue LED's when it's an internal card, lol.  A2320's were not without their problems either, and were fairly rare.

That ebay 2320 is going for about 250 E more than I'd ever pay for it, NiB or not.

That's a GBS8200 in the external case, not an A2320.

I'm aware Mike, and the gentleman that replied left a link to a 2320 on Ebay with ideas about dropping it in an external box with gaudy blue LED's.  See above.
Title: Re: Official Scandoubler
Post by: fondpondforever on January 30, 2015, 11:15:29 AM
Hahahehe. I can see why installing an internal card into an external case is seen as a bit kooky. :biglaugh: Would it work though? I think it would. It would have no practical use but would be aesthetically pleasing to the Amiga Showoff :cool:
 
 Another question. Does the A2320 work on an Amiga 4000?
Title: Re: Official Scandoubler
Post by: Duce on January 30, 2015, 11:42:41 AM
The A2320 will work on the A4000, but burps in some doubled AGA screenmodes, if I recall correctly.

As for putting a Zorro card into some sort of breakout box and running it externally, I imagine it'd be doable with some form of homebrew slot extender.
Why you'd want to is another story :)  

The Bitcoin mining community has been using PCIe extenders for years on mining rigs, and they are used in low profile 1U and 2U servers occasionally, but there's some debate about them affecting performance.  I suppose something similar could be dreamed up for the Zorro bus, though I'd be worried about decent signal at any length.

Post by: fondpondforever on January 30, 2015, 12:46:22 PM
Know that it was made for the 2000 using ECS graphics but is there a solution to stop the doubled AGA screenmodes from messing up. :idea:
Title: Re: Official Scandoubler
Post by: Duce on January 30, 2015, 01:41:07 PM
Yeah, the solution is called the Indivison AGA :)  Or just find an RTG card, which is easier said than done at reasonable prices these days.

There's also the DIY GB card, but it'd take a lot of work.

Because it doesn't interest you, it's stupid?  A rather fun, silly thread turned into a fairly decent, civil technical discussion.  Maybe someone learned something, maybe not, but no one got killed in the process and some friendly discussion occurred.

Glad you aren't a moderator, with all due respect.

+1. Man, you folks come up with some terrible ideas, lol. Although that PCIe extender cable is amusing, I imagine timing for an Amiga video card would be a bitch. ;)
Title: Re: Official Scandoubler
Post by: Duce on January 30, 2015, 08:54:40 PM
Aye, if the long path of the extender didn't get you outright trying to do it with the Zorro bus, even trying to find the components to make such an extender would be a real chore (zorro slot portion, and then the 'gold edge' portion).

It's great fun kicking around wacky ideas, but there's a reason why things like the Indivision exist:  they are readily available at dealers, and are cheaper than most old FF's were, not to mention the fact you don't have to sacrifice a Zorro slot with one.

A2320 in A4000 = puke-inducing color quantization on any mode with more than 32 colors.

Tried it for a few minutes, then got myself a proper 24-bit scan-doubler.

Someone on English Amiga Board said that 2 ECS Scandoubler's installed would create a 24 bit output therefore making it AGA compatible. Would do you think? Thanks.

Are you trolling dude?  Pardon my french, but this is effing retarded.  Would you stop listening to crazy people?

What you CAN do with two Indivision ECS's installed is a dual monitor setup.  Google it, there's videos out there.  Only Jens never released the drivers/software to make it happen, so while it can be done "in the lab", normal people can't do it.

Are you trolling? He wasn't talking about the Indivision. What the post on EAB refers to is this, which is essentially two A2320 put on a single board:

And I'm supposed to know that he was referring to that from his post, how? If there's already a discussion about this home-brew scandoubler over on the other site, why come over here and post a vague and unclear question? Either way, even if cobbling together two of those somehow gives the ability to display an "AGA-style" screenmode, it's not going to make an ECS Amiga miraculously able to run AGA games or other software. *Sigh* I give up. :furious:

The AGA chip "glued" electronically to a plug in board would give real AGA modes, but why?  If you want AGA-type output, get an RTG board.  AGA comes on a system with a 32-bit bus using a 32-bit Zorro 3 bus (aftermarket for the A1200) with 32-bit speeds.  Bandwidth does matter, or is this a foreign concept to the discussion?

Two 5-ounce sparrows cannot carry a 1 pound coconut strung together under their dorsal guiding feathers very far, and kludging such crap together is an academic exercise at best.  Same for an AGA-type output from a plug in board.
