My site is still running on an ISA/VLB motherboard (486DX50) with EIDE drive, etc. I can upgrade to a 5x86-133 (AMD) which overclocks to 160, but with a 33.6K dialup connection, this is the bottleneck in any case. Ah, well, when I win the lottery..... Thanks for waking me up, although it'll still be awhile. -- Ken Are you interested in | byte-sized education | http://www.play-hookey.com over the Internet? |
