It appears I had the fan blowing in the wrong direction. Now that the fan is blowing up the Mac Pro appears to be stable.

I didn’t remove the original fan, since I’m returning it. I did wipe the drive, but powered it off when it got too warm and the display went dark. Not sure how far along the installation has progressed. I even sealed it on the bottom with painter’s tape since it doesn’t leave residue. I’ll...

The fan seems to be doing its job - warm air is coming out the bottom.

The seller wants me to return it, so a return has been initiated. It’s rather sad since the 64GB memory upgrade arrived today. I found another 6-core unit online and purchased it since it was cheaper and still works. Here is what I’m doing for this one while I do Internet Restore on it. The...

Mine was $229. Went with the 6-core unit since the 12-core ones were more expensive. No boiling water for me, but Chinese eBay sellers have the 12-core CPU for about $25. :)

I added Macs Fan Control to it to set the fan to start at a slower speed. However, with the fan not spinning it reports an RPM of 0, even when the app is set to run the fan full blast. Bought another precision screwdriver set with every bit needed for this computer and others.

I started to work on it to see what was up with the fan, but in the process part of the tip of my T5 Torx bit broke off. Almost didn’t get it back together.

It arrived today, but has an issue. The fan won’t spin because it is off-center and is pressing against the round metal plate under the lid. Other than the fan it appears to work. I have contacted the seller and will see what their remedy is. If nothing else, it does have a 1-year warranty, so...

I found a 64GB memory kit on eBay for $35. Of course after purchasing it I found another for $27. :rolleyes: I think I know how to get 28GB: 3 x 8GB + 1 x 4GB.

Mine is a mid to lower-tier model with the D500 GPUs and a 6-core CPU. It did come with a 1TB SSD and 28GB memory. Still trying to figure out the size of the installed RAM modules to end up with that odd size.

I have been looking at Mac Pros for a while, and finally purchased a 2013 Mac Pro. While the older cheese grater towers would have been nice to have, I don't have the room for one and they aren't exactly power efficient. I'm hoping this one is somewhat frugal. Will it replace my Ryzen mini PC...

I'm definitely interested. I tried this particular emulator since my oldest physical Mac is a PowerBook G3 Lombard, and I wanted to play around with some older applications. Quite frankly I was surprised that it worked, but the PCB greatly simplified things.

It emulates a Mac 128k, but if the emulator is compiled the memory can be adjusted to 208kb. Since it runs on a Raspberry Pi Pico, it only has 264kb of memory to work with. https://github.com/evansm7/pico-mac https://github.com/evansm7/umac

I still haven't fully tested it - have to find my micro USB OTG adapter. I know I have a few of them floating around the office.

Success! Just need to update the monitor’s settings to make it less squished.

They can do that because the RP2040 chips are cheap too. CanaKit sells individual chips for $1.00.

I copied the file from http://retro.bluescsi.com/PicoMac-DemoDsk.zip (after extracting it) to my Pico W, then connected it to the PCB with an IDE-like ribbon cable used for Raspberry Pi breakout boards and powered it up. Anddddddd... nothing. I then tried connecting short wires between the...

Took this picture to compare the pinout between the two.

The Pico (clone) boards have arrived. I have three of one that looks like a genuine Pico, but without some of the labeling. The pinout of the PCB matches the genuine parts. I'm assuming this has 2MB of flash storage. There are three of a different clone board that is purple, has 16MB of flash...

After watching a recent Action Retro video about the board from Ron's Computer Videos, I realized I was blind. While I will need to compile when I want the memory size to be 208Kb, there is a pre-compiled image for the Pico. This evening I copied the uf2 file to the Pico, then connected it to...
