I still have a pack of those. That I paid for.

@jchaven
Holy cow, I just found a bag of them that were stashed in an old box with standoffs, coarse thread screws, and molex splitters, oh and some dried out thermal paste.

@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)

"It's just a jumper to the left, and a step to the riiiight."

@linuxgal @pseudonym I'm just remembering Depeche Mode Master & Servant

๐Ÿคฃ Same here. Saw the picture and got instantly the opening cords ๐Ÿคฃ๐ŸŽถ๐ŸŽต๐ŸŽถ๐ŸŽถ๐ŸŽต
@pseudonym @linuxgal A jumper here, a dip switch in the board...
@linuxgal The slave and the master are but a tiny jump apart.
@linuxgal watch out for the deeply politically incorrect jumper setting

@linuxgal Even better/worse was dealing with folks who would install SCSI drives into machines but forgetting to change the SCSI ID jumper on the drives (or ID switches on the back of external enclosures).

Certain servers required drives at specific IDs depending on boot, optical, etc.

I feel so old now
@linuxgal call me old without calling me old.
@linuxgal I did that like once
@linuxgal Dan ben je dus echt hรฉรฉl erg oud...
@linuxgal MFM would like a word, and its ribbons are all twisted...
@ingram RLL would like to join that conversation.
@linuxgal IDE master/slave jumpersโ€ฆ and ISA card jumper settingsโ€ฆ yes, still remember that.
@linuxgal put that choker on me daddy
@linuxgal ngl, was always afraid these would simply explode when not connected the right way ๐Ÿคช

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

Und natรผrlich Master uns Slave auf den Festplatten.

@linuxgal I've seen things you people wouldn't believe
@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
@linuxgal Could someone explain what/ why is he trying to short?
@closeted_unionist @linuxgal I wasn't around then, but it has to do with how a long time ago you would use jumpers to store basic, very low-level settings.
I think here this person is using a jumper to set a hard drive as Master, something to do with multi-HDD setups having a master/slave configuration.
@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

If you haven't initiated a low level format with DEBUG have you even computered at all tho?

Mastodon @ SDF
@linuxgal Anybody else still remembering SCSI terminators? ๐Ÿ™‚
@๐ŸŒˆ โ˜ฏ๏ธTeresita๐Ÿง๐Ÿ‘ญ nice stories from the goodoldpast ...

back in the 90 when i had bought my first computer, a pc, under the pretext to need it for writing stuff for uni, but soon realizing that games were also possible, i wanted to upgrade the disk. i asked in a computer shop for the price; i don't remember how much they wanted for the disk, but they wanted more than 100 DM to "set it up" as they "explained". stuff i couldn't do because it was weird tech like configuring connections an installing jumpers aso. i was quite furious and impolitely declined. later the same week i ran across the tech section in a book shop and instantly saw: "Computer reparieren und aufrรผsten" / "repairing and upgrading computers". that book was only 25 DM. quite a lot for me still, but not 100 DM. i looked up the index for "jumper" and havent been to a "computer repair shop" ever since ... jumper! those were the days ....

@linuxgal
This left me emotionally scarred to the point that I obsessively buy needlenose pliers even if I don't need them.

In case any younger people are curious about why drives were like this, those IDE protocols were developed by drunken pixies, and I don't think it was possible to have drivers for a hard drive under MS-DOS.

@linuxgal that's enough to make a dip switch
@linuxgal Why did Cable Select never work properly
@linuxgal those were called "Cavaliers" in French.
Makes more sense to me.
