Well not to compare dicks , but every reference by PC writers I've seen descibes MCA as a superior architecture. Had IBM not attempted to flex it's muscles by inserting a proprietory clause, hence forcing Compaq et all to come up with IDE we would now likely have a PC system much superior built on the basis of the MCA advances. And ESDE was much faster than MFM. The SCSI built into the PS2 models like the 8557 even with the bastard (rs6000) external connector was even faster as well as the faster serial I/O. IBM also introduced VGA with the PS2. With the reference disks PS2 was plug and play on the PC long before Win95 . I love my 8580. Built like a tank. Virtually indestuctable. It sits under my desk as a companion to this newer machine I use on the net. A true classic. I'm always on the lookout for cheap adapters for it, and at some point will add a 486 daughter board. Right now I have DRdos and OS/2 on it , but eventually it will be my Linux mchn. I also have many older micros. Each I consider unique , with thier own particular quirks and virtues. Older isn't the point. Its importance in the overall development or uniqueness is. I must admit tho that my ST is more fun and my fave. To each his own. ciao larry lwalker(a)interlog.com
