Mac II PSU in a IIfx

[CelGen]

Scored a gutted IIfx (all that remained from the recycler was the case, the board, the ROM SIMM, and the ram thank god) but parts like the metalwork for the drives, internal cabling, speaker, and the power supply were gone. This is a system I'm willing to sacrifice parts from another Mac II and all I got is my minty original Macintosh II. I heard the power supplies between the two were different. Was it just the fan that changed?

My understanding is when people upgraded mac II and IIx to IIfx with the Apple kits they just swapped motherboards.

What are the specs for the II power supply so we can compare to the IIfx one?

 

[Byrd]

II PSU = IIfx PSU, exactly the same except the IIfx has a temperature-controlled fan (and is considerably quieter as a result)

 

[Strimkind]

I may be wrong on this, but there are a lot more Mac IIfx units then working Mac II or IIx out in the wild.

From my point of view where I have seen a few IIfx units but no IIx or II's that I would keep the mac II as is and look for another parts machine elsewhere. I'd love to see an intact original Mac II.

I have a spare IIfx metal hard drive sled you are welcome to if you pay postage. It came from a badly corroded IIfx so there is some corrosion, but not really ugly.

 

[CelGen]

Not sure what piece of the hard drive bracket metalwork you got. I'll just show what's missing with a photograph.

 

[Byrd]

So you'd be missing

- PSU

- Nubus cards - video card at the least

- Drive tray that mounts onto the top of the white plastic risers

- floppy and hard drive, and brackets for these (which aren't essential - you could make your own perhaps with small risers/screws)

- floppy drive and hard disk cables (same as in pretty much any other 68K Mac)

... why can't you compare to your Mac II?

There's a (more or less) flat plate that mounts on those white plastic stand-offs and the HD bracket encloses the HD and mounts on top of the flat plate. I had the flat plate and offered it for free on here a few months ago but nobody was interested so it went to the metal recycler. The HD bracket is free if you want it, just pay postage.

I can assure you. From my massive lot of NuBus cards I'm sure I can find a beastly enough video card.

I do also have the bracket for the floppy drive. I found it rattling around int he case when I found it in a pile of gutted PC's. I should be able to make new SCSI, floppy, and power cables using components that are scattered around our shop.

Sure, PM me and we can discuss mailing that tray. I do also in fact also own a IIx but its power supply seems to be sorta dead unless I was not jump starting the batteries right. It's too new of a system for me to pull parts from I feel.
