Title: A1200 transplant
Post by: blanning on March 02, 2010, 05:09:43 PM
Has anyone taken a dead 1200 and replaced the motherboard with something like a keyrah, an itx motherboard, and WinUAE?  You could even use a right-angle PCI adapter and get a PCI board in there, like a scsi board or a PCI catweasel or both.  Maybe use a real floppy, or a CF card reader in its place.  Has anyone done this?

I was thinking of doing exactly this to run AROS. Unfortunately the height of the A1200 case isn't enough to accommodate any of the supported boards with their heatsinks attached :(

After investigating a few ITX motherboards, I noticed the huge heat sinks.  Gaudier than a rear wing on a rice rocket.

With regard to hardware, I seem to be a senior citizen these days.  I seem to remember there being something (a heat pump?) that attaches to the CPU and puts a heat sink somewhere else.  Maybe there are others with a fan that could be lower-profile but work as well.

That sounds like a peltier device

Get a Via Epia PX 10000G. No PCI slots, but it won't be a problem getting it to fit.

The C7 1.0 GHz CPU should be enough for WinUAE. It's not cheap though.

It's not a peltier that I was thinking of.  Although a peltier might not be a bad idea.  I used to have one and the warm side heat sink was huge.  I think they're power-hungry too.

I've got one of these in my linux router.
 
Uses a power supply the size of a phone charger.
 
Single core atom and very low profile.

No... But I do have an A1200 in an A1500 case.. Very strange.

That's actually kinda cool Scuzzb494!  Too bad there's no easy way to take advantage of the case and add a Mediator/Zorro type combo.

That's interesting.  Although I fail to see how that works better than any other case... at least it says amiga on the outside.

I toyed with the idea of making a case out of a simple piece of plywood (under the motherboard) and a piece of plexi on top to cover it.  Maybe put some mood lighting under the plexi...  I thought about something similar for the 2000, but more complicated to support the zorro and isa cards, and some drives.  

Something like this would be easy for the PC/WinUAE route also.  Then again, I could just get a plexi case and put an ATX motherboard in it and be done with it.  A 1200 with a keyrah would look nice next to a plexi case full of goodies.

Thanks for the link.  This is exactly what I was trying to describe.  Now I'm thinking an a500 might be a better donor.

This (http://linitx.com/viewproduct.php?prodid=12311) would work, you could run UAE in something like OpenBSD?
