I took a 4D/20 instead (I think. It's a Control Data OEM version, and the name written on it is "Cyber 910". R3000, about 20 MHz, 16 MB of memory, IRIX 5.3. I've compared building software on it and on a P5/133. You can build bash on the P5 in about 90 seconds, on the 4D/20 it takes 40 minutes :-( Greg -- See complete headers for address and phone numbers finger grog@lemis.com for PGP public key To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
