WRONG! >WRONG!!!< For the sake of arguement, let's define a micro as a computer with a standard semiconductor chip-set (68000-series, 32032, 80286, NCR-32, etc.) and a mini as something like a VAX, a RISC machine and others.... Machines with high speed memory buses and SMD disks will run FASTER than a VAX 780 and certainly faster than a VAX 750 (not to mention a PDP-11 running V7 :-)) I have run benchmarks on many machines from CONVEX to PDP-11/23 and I KNOW that for computation the VAX is bad in price/performance. In terms of I/O bandwidth, it becomes of function of controllers, buses, and disks as well as memory and CPU. With the wide variety of all those things in the mini market, there are machine that optimize all those things and beat the vax hands down. >Also, don't you mean Maxtor 5.25"?

Anyone have any idea >why not? The 8" are. The OEM's I work for on occasion use the 140 version which is VERY reliable. They are still waiting on the 380 to evaluate. This implies to me that they are available yet, so people CAN'T use them. >-- > Peter (Made in Australia) da Silva -- Stan uucp:{ihnp4!shell,rice}!neuro1!sob Opinions expressed Olan ARPA:sob@rice.arpa here are ONLY mine & Barber CIS:71565,623 BBS:(713)660-9262 noone else's.
