[COFF] Re: machine code translation,as mental architecture models

According to Dave Horsfall <dave(a)horsfall.org>: Yup, I recall looking at the disk drivers which had a comment saying that overlapped seeks on RK disks didn't work. At Yale our PDP-11 had a pair of 2314-style RP drives. Its controller did work and I stayed up all night one weekend debugging a driver that queued and sorted requests for the two drives separately and did separate seeks. It made a lot of difference, something like 30% more transfers/minute. -- Regards, John Levine, johnl(a)taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
