fediverse ruminations, gab mention 

On top of this, Adaptec's XT controllers had a chip not unlike the AIC-500, which converted from the DMA protocol the PC/XT expected to SASI.

All this led to the "triple-function" chips that everyone used pretty much throughout the 1990s (unless you were Quantum or IBM, who had by that point decided to make their own all-in-one controllers).

When SCSI came out and added a bunch of extra features (parity, multiple devices), Adaptec added a chip that converted between SCSI and SASI, the AIC-500.

Yeah, I've been reading about ancient hard disk controllers again, and one thing I found out is that the Adaptec AIC-300 and AIC-010 (which were in a *bunch* of old hard drives and such) were designed to connect directly to a SASI interface. Adaptec's SASI bridge boards used them.

Since SASI eventually became SCSI and was a lot more flexible.

One thing that will always baffle me is why Western Digital went with a custom task file (which eventually became ATA/IDE) for the PC/AT HDC instead of just reusing SASI from the XT controllers.

I dreamed I picked up a new radio station calling itself "104.5 The Ride" which had a fairly standard Classic Hits format except instead of commercials they played clips from My Little Pony interspersed with cryptic messages about some kind of "god".

It was literally like something out of a creepypasta...and tbh it was kind of awesome

wait, Apple Music works on *Android*? Will wonders never cease...

After swapping the memory around *again*, I was able to get things stable enough for OS X and the FreeBSD live CD to run with 768 MB installed. I'll worry about doing more with it once I'm done messing with the Shuttle up here (I have a mini-802.11n dongle coming for it today).

Now, my other question is about the G5. I upgraded the RAM and put in a new HDD, but *why is it still so slow?* The *G4* seems quicker at times. It's acting like its caches are off!

The low-side caps in switching power supplies of this era are notorious for going high ESR and outgassing, so I'm starting to wonder if I may have a failing power supply.

I did some poking around on the G4, and it turns out the cap I suspected near the memory has a really high voltage on it, about 28 volts. This seems to be the high voltage for the FireWire, not anything to do with the memory.

All three voltages from the power supply are reading low at the ATX connector, and +12 is reading lowest of all at 11.5 volta. HMMMMM.

I may try putting the Nvidia card back in, as much as I don't want to, simply because this thing's PCI bus seems to have a weak stomach.

In other news, FreeBSD 12 loads and boots, but freezes about Midway through hardware detection. I'm starting to wonder if this machine is damaged in ways I can't see. :P

Apparently this has been an issue for a while. Supposedly the kernel *will* boot in 32-bit mode, but that's no good if I can't even get it loaded...
