The 4-port USB 3·0 hub that's clamped to the side of the iMac.

hub

I was wondering why the USB 3·0 ext drive wasn't mounting on the desktop. Duh! it has a power switch at the back. All good now.

Got the USB/Thunderbolt ports on the new iMac sorted. One USB 3·0 is used to connect an unpowered USB 3·0 4-port hub that's clamped to the side, all ports face forward.
The other USB 3·0 port feeds the Logitech 15-watt 2.1 subwoofer stereo speaker/soundcard/powered USB 2·0 3-port hub thingie. One of its USB 2·0 ports is free, the others are used by the scanner & Apple DVD drive.
Nothing is currently connected to the front-facing USB 3·0 hub, they're for backup drives as needed & USB thumb drives. One of the two Thunderbolt 3 ports is used, connecting via T/Bolt 3-T/Bolt 2 adaptor then a T/Bolt 1 to FW 800 adaptor/FW800 cable to an external HD that's for storage.
Four USB 3·0 ports were not adequate. The SuperDrive & three ext HDs, one connected, the other waiting their turn all sit to the right of the old camera case that's used to elevate the foot of the iMac to bring it up to proper working height. The Fraudband* router/modem is on the wall behind the USB drives as is the AirPort Express which makes the USB laser printer into a networked one.
The cordless phone system plugged into the router/modem has its base station on the left, between the iMac stand and the scanner.

Trump's anti-Obama eclipse meme doesn't make scientific sense. http://time.com/4914037/donald-trump-barack-obama-eclipse-meme/

Which part is that? Cos at the time of posting, it was still Thursday in eastern Australia.

Got thru another hard night that needed the influence of six dual-purpose antacid tablets. Normally only two are necessary when so afflicted.

Converted a USB 2 ext HD to USB 3 with a cheap case from Amazon USA. Of course, the supplied 2A power brick is no good, it has the wrong prongs. I used my existing 1.5A brick (both are 12 volts DC) and it works OK.

How is this so? It's not yet Friday in Australia!

Damnation. I can feel a gout attack coming on. Totally out of paracetamol & ibuprofen, having to rely on aspirin for pain relief. Using two anti-gout meds as well, an anti-inflammatory and another that can lead to aggressive bowel movements

There's an odd fault with the 240 volt convection/radiant panel heater in this room: it just will not heat to over 18ºC, despite having settings for up to 27ºC. Ah well, at least it'll reach a comfortable level. Just.
