Hey, does OS4 have PPC TCP/IP stack now?
If it does it is probably in beta stage
Anyway, Pegasos I is sold out and I recall they are not making those anymore. They have some units left for special cases tho. So if you want Pegasos you have to wait for Pegasos II now.
OTOH A1 is available but without OS4. So if you want OS4 you have to wait. Quite interesting situation.
