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


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 (#ยค&%%& 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.

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.................


Exactly how many wires are we talking about here?

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.

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.

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 ).

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.
