Nope...  the Apollo DN series workstations are pre-HP Apollo systems (before 
HP bought out Apollo Computer) and are 68K based systems.  While they are 
pretty majorly different, the Apollo DN's are similar in  CPU/speed to the HP 
300/400 series systems.   

The HP 700 series systems are PA-RISC based systems... and entirely different 
beast.  There currently is an effort going on to port to the HP700's, check 
the "port-hp700" mailing list... and OpenBSD is working on a port.  Not sure 
how far either has gotten at this point, but I'm pretty sure they are not 
what anyone would consider a fully functional "port".
