PCI to ISA card

I was looking for a PCI to ISA card in order to re-use an ISA card with
PCI connector of modern PC. I found costronic.com solutions.
Do you know further solutions?

Thanks in advance

 

Check out newegg.com they seem to have a few unique items. or 'Google" for
one, sure you will have a few good hits to follow up on.

 

A search on "pci to isa" + card turns up a few hits. PLX has an RDK
for the 9050 PCI to ISA bridge, but I suspect it's pricey.

It isn't easy to do, since the PCI technology is totally different from
the comparatively simple ISA bus.

Your best bet will be to locate an adapter card, or a motherboard
having both PCI and ISA slots.

Actually, it's not hard to do at all, unless the ISA card is a bus master
(_very_ few were). Many devices use the PLX9050 PCI to ISA bridge to do
exactly this.

Thank you all for the replies.
I decided to use a development kit like PLX one (PCI 9052RDK-LITE, the
upgraded version of PLX9050) for my purpose, so I'm looking for a
development environment like that, for migrating ISA card to PCI
connector.

Best regards

 

How can an ISA card be a *bus master* ?

ISA is just the micro's data and address bus basically with a few extra pins
to the interrupt controller !

I think only EISA and MCA cards had that ability prior to the adoption of
PCI.

Then goes and wonders over some of the earlyish Adaptec SCSI controllers e.g
AHA1540/1542. In which case how did they do it ?

The device asserts a DRQ, waits for the corresponding DACK, then
asserts MASTER, at which point it can drive the address/data/control
lines as needed.

It's a *little* more than that.

No, it was there in ISA too, though not often used.

Yep. There was also the IBM Multi-media Modem (sound card/modem
combined on one DSP) that used bus mastering to swap its OS and data in
and out of system memory.

 

Thanks for the filling me in on the missing bits. I'll have to revisit the ISA bus
standard to get to grips with this.
