#Tech #Q1

@Karma_J @linuxgal this week...

@linuxgal Interrupts und IO-Adressen per Jumper auf ISA-Karten festlegen... good old times.

Und natürlich Master uns Slave auf den Festplatten.

@stuartl @benroyce @neverbeaten @linuxgal 5 or 7. The line "SET BLASTER=A220 I5 D1" will remain etched into my brain forever.

@stuartl @benroyce @neverbeaten @linuxgal Yeah, I think you're right. Although it's so long ago it's mostly just a faint wisp of a memory.

I also remember making a cable to connect a 23 pin Amiga monitor to a 15 pin PC VGA plug. It worked too! (We had all the cable-making equipment where I worked.)

@linuxgal I've seen things you people wouldn't believe

@Karma_J @linuxgal
My daughter, approximately 6 months, working on her IBM PC, early 1984.

@stuartl @neverbeaten @linuxgal

Well now you know why i was so frustrated

And thanks a lot Stuart. You're 30 years too late. You could have helped me out with this a little sooner!

@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!
