Hello everyone,
I got several Super IO cards(Re: Bought these (retro) hardware today), one of them I can't find any information on the internet, there is only the string of CY-573-V1 on it, no other information, can anyone help me get the jumper setup instructions for it?

Cyrix 486DLC-40, 386-VC-H, 16MB, GD5422, ES1868F

Intel 486DX4-100EW, VI15G, 16MB, WD90C33, ES1868F

AMD5x86-133, HIPPO-15, 32MB, S3 Vison 964, ES1868F

K6-3+ 500, T2P4, 128MB, Millennium II, Voodoo 2 12MB, SoundBlaster AWE32

just going by the ISA pinout & photos

JP5 clearly IRQ selection
position 8 is connected to IRQ7
position 7 is connected to IRQ5
position 6 is connected to IRQ5
position 5 is connected to
position 4 is connected to IRQ3
position 3 is connected to
position 2 is connected to IRQ5
position 1 is connected to IRQ4

I'd guess printer IRQ position 7 or 8, serial port A position 1 2 & 3, serial port B position 4 5 6

JP4 Just a guess
1 & 2 printer port enable/disable/portselection
3 &4 serial A enable/disable/portselection
5&6 serial B enable/disable/portselection
should be easy enough to test, boot the computer with the card in it from floppy or harddisk,
and run checkit or msd or a similar program that shows you which ports are available and at what location and run through the JP4 jumper possibilities.

Testing the IRQs is another matter.

Right to repair is fundamental. You own it, you're allowed to fix it.
