I should have said that the 7i92 performs the same function as the PCI card. Since it's interface is Ethernet you can't just pop it into the PCI bus. Yes, you can talk to the 7i92 with just a plain network card or on board port from the PC. So it would be NIC->7i92->BOB->machine.
The 7i92 still needs a BOB as it shouldn't connect to hardware directly. You could use a 7i92 and your existing BOB or if you want to scrap your current BOB, you could use a 7i96 which is basically a 7i92 & a BOB all in one package. A 7i96 would be NIC->7i96-> machine On Sun, Jun 13, 2021, 10:29 PM R C <[email protected]> wrote: > > On 6/13/21 8:14 PM, Milosz K. wrote: > > Hi Ron, > > > > The MESA card, 7i92 as we are talking about in this case would replace > your > > failed PCI card. > > Uhm, I thought that would be an ethernet card? > > > We might need a bit more info on how you have the 2 machines wired and > > implemented in your present config to suggest the correct MESA solution. > > well, Originally the machines came in an Paxton/Patterson enclosure, > with "optistep" electronics, which is basically a parallel port > "thing" but the pinouts are all different.
