That last series of questions related to 7200/90 sparked interest here.
I have a 7200/120 with Sonnet Technologies G3 upgrade card that 
installs into the cache slot.
This upgrade card has it's own RAM slots so the machine has a total of 
about 180 Mb of Ram at present. I also would rather do NetBSD rather 
than Linux.
So, has anyone had any experience with this type of setup (preferably 
successful experience)?.
I have several older Macs that can't or won't run OSX and they work 
fine, I'd like to get them going with NetBSD to do odd jobs around my 
network, like DNS, database servers
and back end web servers behind a reverse proxy (which is going to be a 
FreeBSD machine, as PC parts are cheaper than a new Mac, even 
considering the Mini,).
Thanks in advance
