@linuxgal Im 128 y.o.. I remember this.

@linuxgal master/slave....

30+ years ago for RAID with SCSI drives not only had you to set the IDs manually but depending on the server/controller/number of drives you had to tell the SCSI controller to spin up the drives one by one as the surge in current would overload the power supply.

@linuxgal I remember the consequences for getting it wrong

@hermannus @Karma_J @linuxgal RS-488 was a good connection for the time (just add to remember that ID 1 = tape, 4 = printer, 8 = floppy)

@linuxgal

@linuxgal Could someone explain what/ why is he trying to short?

@linuxgal Enslave your IDE Disk - that is fresh new stuff if you low level formatted you MFM/RLL Disk using debug.com - no thats not a domain https://dosdays.co.uk/topics/format_harddisk.php

@closeted_unionist You had to physically short the jumpers so your computer knew whether to make the hard drive the primary (master) or secondary (slave) drive. That way you could have a C drive and D drive, with Windows booting from C.

@linuxgal The magical Cable Select (CS)

@Karma_J Boahhh. Remembering those days!!! @linuxgal

@linuxgal Mmm...

@linuxgal

Thanks for the explanation.

@Karma_J @linuxgal
Da war die Welt noch in Ordnung!

@benroyce @neverbeaten @linuxgal why did 5 immediately drop in my mind...?

@Karma_J

That takes me back to PC class in the 90's. 🥲

@neverbeaten @linuxgal I distinctly recall a time in the mid 90s when my family's home computer had an IRQ conflict between the modem and the mouse, such that the moment you connected to dialup, the mouse stopped working. I didn't mind, because I was using telnet and lynx.

But apparently after I went away to college my parents tried AOL, and they got charged for a few months because they couldn't click on the button to cancel their account.

@linuxgal Anybody else still remembering SCSI terminators?

@geogoeroe @neverbeaten @linuxgal

the amygdala where your brain processes fear pain and horror is involved in creating strong memories

@linuxgal I know
