"it's now safe to turn off your computer"
That's how old I am

Fuck
I had a friend who edited the .jpeg or whatever in the shutdown sequence to say “it is NOT safe to shut off your computer” and waited for his family to freak out.
And the power switch was like KA-JUNK when you pushed it, because it was a big ol' switch that actually physically connected and disconnected the power.
"It's now safe to turn off your computer" went away after we moved to software power control, where the operating system could signal the power supply to turn off.
I had my computer plugged into a power bar and we'd turn off the power bar to turn off the computer so that we wouldn't wear out the switch on the computer.
People actually thought you'd have a computer long enough to wear out its power switch.
I knew far, far too many people in HS that just hit the power button without actually shutting it down.
The one I remember best was having to use the DOS 'park' command before you shut down the PC. I guess I am that old.
Huh, never ever seen that. We always used the rule "you can shutdown the computer when you can see the C:".
What does park do? Put the HDD arm into a parked position? Never needed that for ours, but we also had a blazingly fast 486 with a massive 250 MB hdd.
Yeah, old drives didn't autopark like the IDE drive in your spiffy 486. I had an XT growing up, and dad was militant about having us remember to park the drive when we were done with it. I think by the end of the 80s, all drives were IDE and were autoparking, so the command was deprecated.
Damn, I had a Tandy 1000HX (very much not a 486) and never had to do that. Maybe because, despite having a hard disk, it had DOS on its own ROM.
Cool, I've wanted an OS ROM chip since the early nineties, and often wondered why nobody seemed to be doing it. Guess they were all along!
You technically didn't have to park the old MFM and RLL drives, but if you didn't, then you just had the drive heads resting on the platters after you shut them down. Then if you bumped or moved the PC at that time, it could scratch the disk like a record. If you never tried to move it, there probably wasn't much risk.
From the sound of it, the HDD in your Tandy probably would have been an MFM or RLL drive, and depending on the drive model, it either autoparked the drive heads or didn't. As a PC clone running MS-DOS, the command was probably supported, but maybe not needed. Or you may have just been the equivalent of one of those rebels who held down the power button every time they wanted to shut down the PC and always got away with it!
I never had to do that, because our computer didn't have a hard drive. We booted DOS right from the floppy.
I'm right there with ya. Don't forget to make sure you set the interleaving correctly on your Winchester drive!
Yup. Thankfully that “feature” went away real quick and it became automatic.
Is that Windows 95?
Any Windows machine that does not support ACPI or has it disabled. IIRC Windows has required ACPI since Vista.
95/98 and ME/XP to a far lesser extent but it was 98 for me lol
I feel you man. Very nostalgic!
The ole AT power supply standard. Nice.
