As you see, there is a 120VAC -> 9VAC step down transformer bolted to the top of the ATX power supply.


Is the transformer alays connected to mains, or did you add a relay to toggle it as the PSU starts?

I used an AT PSU for my C-64T, mainly because I wanted a single switch to turn the PSU + trafo + monitor totally off. With an AT PSU, I didn't need to hunt down relays, I just tapped power to the trafo after the switch.

Probably a non-issue, as there are no power switches in original C-64 or C-128 PSUs either. Always good to think green, though. :-D

http://jope.fi/c64t/ in case you're interested.

Mine is not tip top, but I tried to make it as neat as possible.. It needs a neater port plate for the back of the tower, but otherwise I'm rather satisfied.

I also opted not to wire in video -> VGA converters, my flat panel monitor has s-video and SCART connectors behind it.

Only a few people have done such a project and no one has published information on it.


Nate/Vanessa Dannenberg's C-128 tower project has been on her website since 10 years ago.. The site seems to be down currently, but you can check out archive.org:

Hope it comes back up some day so you can see the pictures.

Standard 3.5 DD floppy disks? Yes. Standard 3.5 PC drives? No. I will convert a 1581 to go internal.

The same tricks apply for the 1581 as the Amiga concerning the drive mechanisms. You can modify a PC drive to be Amiga/1581 compatible and it will mount neatly in the front panel.

Mine is done like that, I'm using a modified PC mechanism.

Did you reference anything for your project? An Aminet hack maybe?

Just the knowledge about PC drive modifications you can gather from amiga.org and eab.

Get DC to pin 2 and RDY to pin 34 and make the drive answer to DS0. ;-) The Brazilian dudes figured out a way to cheat the RDY signal by jumpering pin 30 to pin 34 on the drive, but I haven't tried that myself.
