Maybe call it an "iSink"… after indibil’s original approach?

It isn’t pretty (yet) but the first “replicant” here is finally complete.

Very good job @aBc. Keep in mind that this heatsink, in addition to being made of copper, which greatly improves conduction, has a better construction than the original, which if you look closely, is a thin aluminum base, with INSERTED fins, which worsens conduction compared to that they were part of the same block.

Maybe you have a few less fins because I bought a 50x50 heatsink and yours was 50x100, and in the manufacturing process it may have a lower density of fins, but don't worry, the original heatsink is ridiculous, I don't even know how it dissipates. And a heatsink with pipelines is only a way to reduce costs, an entire block of copper conducts heat much better.

Maybe this heatsink should be called "aBsink", if my bad English doesn't make it sound bad

Heyho. So here I am with a Mac Mini (1.5Ghz) running (nearly) Mac OS9!

I started my Mac career getting on for three decades ago with a lab Quadra. Then two decades ago I did a temporary support job that involved getting a G3 with dual boot OS X/Mac OS9. That lead me into full time Mac usage. But then Intel beckoned and for some time my only Mac OS9 access was virtual (Executor, then Sheep Shaver). Some for just play, but there's a little app that I need every few years or so and for that I have a Mac OS8.6 VM via Sheep Shaver.

During this time my only PPC Mac was a unbootable MDD that I finally lost patience with six months ago and gave it away. But now I find my way to this forum and immediately onto ebay to find a suitable Mac Mini. I bought what I thought was a 1.42Ghz one. Turns out its optical drive is broken (the case is currently off and to eject you need to move the bar upwards) and it's actually a 1.5Ghz one but it has twice the RAM of the listing (1Gb).

I messed about with USB and FW drives before learning that neither of these will boot! Then onto CDs until I found that 700Mb ones are not recognised in this drive. Whilst waiting for ebay to deliver me some 650Mb CDrs I used SuperDuper to create a USB bootable external drive, then when booted from that drive I used iBored to put the v9 installer CD image to the internal drive. I guess now I need to slow down and wait for those CDrs. But I already find myself reading the thread on using a mSATA disk via a SATA/IDE adaptor...! Cracking. Thank you to all who have spent so much time on this. Cheers Ferg

                     Could use a bit of cleaning (copper dust particles, etc.) and some emery cloth smoothing of the rough fin edges.

It's great to have you here in Mac OS 9 Lives, as well, @laulandn!
