I have come to the conclusion that IRIX 4 doesn't work without a network interface.

'autoconfig -fv' will clearly tell you it can't probe enp0, enp1, ... and also none of the ipg or et interfaces, but then "ifconfig ipg0" will hang the system. This means the network part of the init scripts will always hang the system if you attempt to switch runlevels. Perhaps an older version or IRIX, without X11 but with NeWS can run without network, but my goal here is to run the Diagnostics on the (graphics) hardware and the oldest Diagnostics I have is version 4.0.1

So I caved and installed a VME ENP10 card. And then the system started behaving:



It does wild color map flashing because it doesn't have enough bitplanes. Had not seen that since the 8-bit Indy I had at $WORK back in the nineties



Unfortunately, most of the demos don't work because 'powerflip' wants a Z-buffer which this systems sadly doesn't have. If anybody has a lead on a ZB2 board, or a 24bit color DE3 board I want to buy it from you. Actually, any other DE3 board probably has enough of the special SIMMs installed to fill all banks on mine and make it full color. To be honest: I'm interested in any (spare) part for the Professional IRIS.
