@benroyce @neverbeaten @linuxgal I thought it was IRQ5. 3 & 4 were for COM2/COM4 and COM1/COM3 respectively.
@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 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)

@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.

Thanks for the explanation.

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

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

@linuxgal
And make sure your interrupt request settings are correct so your daughtercards will work.@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?
