Title: Biggest mistake?
Post by: J-Golden on September 26, 2005, 09:41:50 PM
So I broke down and got the SD/FF from Eyetech which IS the Scan Magic.  Said it was for A1200/A4000 and I, stupidly went ahead and got it.  why do I say stupidly?  Look at my tag... A4000T.

The instructions don't say anything abo. a A4000T installation, infact it only has written instructions for the A1200 and a photo copied picture of a A4000 MoBo that says "Fitting to A4000".  I looked at the manual on the Big Book site and that had a bit more info but it doesn't look good...

Tell me strait up, am I screwed?

I'm sure that electronically, it should work. The question is, is there enough cable length between Alice and Lisa clip-on modules in order for successful mounting? I think this should be your only concern, and of course correctly orienting the modules before clipping them on. :-)

Hmmm, looking at the positioning of the two chips on the A4000T motherboard (http://www.amiga-hardware.com/download_photos/a4000tmb_rev4_4.jpg), it seems like there won't be enough space for the modules to fit. :-(

Yeah, saw that too.  :madashell:

I ther such a thing as a riser for that style of chip?  I MIGHT be able to pull it off is I could get the clip on the Lisa to sit higher.

Also, the "NTSC/PAL" jumper sits right between the two...  Prob. just snip thise down and solder the connection for NTSC.

Can´t you sell it again on Ebay worldwide ??? You might even get a profit out of it !!!  :lol:

Where is the problem ? Just cut the cable and solder longer wires in place. It`s only two lines so no big deal.

@ Lemmink

IIRC PaSha also had this problem. It is because of the disks module. He couldn't file the PCB of the FF enough and he couldn't avoid the pins of the disk module. There is another thread somewhere here about it.

If need be I could open up my A1200T tomorrow night and measure the SD/FF PCBs and cables to give you an idea.  I could post a pic of it too.

tankz but from the other post it doesn't look to good.

At this point I'd be willing to trade for an internal sollution that would work in a A4000T or and External that does AGA.  Mine is the Scan Magic so it IS a SD/FF and it's brand new too...

I have the external Eyetech `EZ-VGA Plus' Scandoubler/FF for my A1200 desktop. You have to bare in mind that when you have an external one it will protrude an extra 4" from the back and when it's made from sheet metal like the EZ VGA that could be a lot of strain on the video socket when dangling off an A4000t.

:-)

You could try getting/making a 23-pin video extender male-female but probably your best bet is the internal option.

Just out of curiosity, why don't you get yourself the wonderous Picasso-IV with it's superb internal Scandoubler/FF? It's the best there is since it supports full 24-bit unlike the 16-bit hacks...

I have an A4000T sitting right here that I installed one of these units in. I am not overjoyed with the performance, but it is better, until I can get the Picasso card working again.
I did have to extend the lines (wires), but that is a snap.
Eye ball everything carefully - it may not be as bad you think.
It's a shame you're so far away, I could pop it in for you.................

Uh, no. The part with two lines on it goes on the Lisa chip, and fits perfectly.
The problem is the main PCB that is supposed to go on Alice, this can't be fitted due to the A4000T Floppy/SCSI-module (#¤&%%& DCE for not taking the A4000T into consideration when making this thing and offsetting the PLCC socket....). Possible solutions: Soldering a lot (presumably) of wires from Alice (via a PLCC socket clipped on) to the ScanMagic, or use a PLCC socket extender (ridiculously expensive, at least the ones I've found so far).

And, anyway, rumor has it that this thing isn't quite AGA anyway, only doing 16-bits (8 red, 4 green and 4 blue). Please correct me if I'm wrong here (seriously, I would like to be wrong on this one :-D)

A little off topic: Does anyone know about a TFT/LCD monitor that does 15kHz on the VGA input? Please provide manufacturer/model number.

Exactly how many wires are we talking about here?

Hmm, mine can. It's a Medion MD6144AO 15" TFT (or is it LCD, can newer remember the difference?). The only 15 Hz screen it hasn't been able to display until yet is Dynablaster, all others work fine, but 15 Hz isn't crystal clear unfortunately.

I bought a Medion 17" with the same design layout hoping that it could display 15 Hz as well, but that one needed a scandoubler, so I'm looking for one that's better than my MicroniK Scandy :-)

-EDIT-

Here (http://home1.stofanet.dk/amiga/TFT.jpg) is a picture of the monitor displaying a 15 Hz screen. Dunno if anyone can see it from this picture, but there are some vertical lines on the display. Not that big of a problem to me though, as the display delivered by my MicroniK Scandy is actually worse...
Title: Re: Biggest mistake?
Post by: PaSha on September 29, 2005, 03:58:33 PM
Hmmm.... Medion? Nice surprise, they're sold under plenty of names for pretty decent prices here in Norway :)

And one of our store chains (Elkjoep) have a 30-day no-questions-asked full refund return period...

Shopping time, me thinks.

-Paul

Edit: btw those vertical lines are a typical LCD artifact often present when displaying something lower than native resolution. 1280x1024 Native should be perfect for hires-lace though (640x512) as every pixel should be exactly doubled.

Post by: doctorq on September 29, 2005, 04:08:48 PM
Keep in mind that only the 15" model can do this, but with the 30 day no-questions-asked refund I guess you have nothing to loose other than the time wasted.

Regarding the vertical lines I guess anyone can learn to live with it. Unfortunately this monitor can only go up to 1024 x 768 :-(

CRAP!!!!  I grew up and lived my whole life in Beltsville MDa and NOw when I need a fellow amigan (NCAUGer?)  I'm on the other side of the world... :(

If you could send a diagram or inf on how you did your I MIGHT be able to do it myself...

TANKZ!

I have an Amiga RGB SCART cable I connect to my 7 inch LCD monitor that has a RGB scart input.

http://www.dabs.com/uk/productView.html?quicklinx=3162&familyid=203

I am in the states and mine does not do PAL, atleast from the amiga but it does RGB with the scart cable and will do 15 khz.
If you need a monitor to play games on and use the graphics card for real work, this is not a bad idea.

Another idea is to use a RGB scart cable to a RGB VGA transcoder/upconveter.

Have not tried this but it might work as well.

The two lines going to the Lisa needed to be extended by an inch or so on the unit I have. The PCB is a VERY tight fit, but it did go in. However, A friend has a 4000T that this unit would not fit in. There is now way the PCB would go in, so I see first hand what you are saying. I wonder why? different version mobo?

Nah, AFAIK the only A4000T mobo ever used in production is the rev4.
Are you talking about the very same SD/FF fitting in one A4000T, and not another one? Makes no sense, unless ofcourse the one it did fit in, is a different mobo rev (genuine C= A4000T perhaps? A until now unknown Rev3 mobo? If so, please take pictures and send them to www.amiga-hardware.com ).

-Paul

EDIT: Two lines to LISA ?!? On mine, the main PCB fits on LISA, and the two-line PCB fits on ALICE.

After shaving off as much of the main PCB as possible, it would fit on LISA, but the edge of the PCB touched the pins of the SCSI/Floppy module connector.

OK STAND BACK!!!!!  I've got a dremmel and know how to use it !!!!!!!

And it looks like the only sollution I have too.

UNLESS!!!!!

Is there any one out there who would trade me for a SD/FF that WOULD work on the A4000T?  My scan majic is brand new and unused.  I'll wait till wed. for any responses... If no takers by thursday, it's hackin' time!!!!!!!

Well, in a thread a long time ago I offered to switch scandoubler with someone in Argentina, that needed one for his video slot, and the same offer goes to you of course. I think the same offer went to Pasha when he had troubles installing his.

It's a Scandy In from Micronik for the videoslot. It works, but I can't remember if it has flicker fixing. It's an offer anyway, but I doubt you'll take me up on it :-)

;)  I looked it up on the BBoAH and your right, it doesn't Flicker fix.  I DO apreciate the offer though and other wise would have been a perfect fix!
