First, a couple of days after installing it I had the same problem that grayson@cartan.Berkeley.EDU.UUCP (Matthew Grayson) had --- the drive just would not show up on booting. His suggestion (made for the Dataframe series of drives also solved my problem: Hit SHIFT-OPTION-COMMAND and select the Control Panel. Then answer Yes to the clear PRAM message. Next a comment on the Easy Drive timings: on the suggestion of Tim Smith, I formatted the drives with various interleaves and ran disktimer2 on the various formattings: (all are with MacII, 1 meg Ram, NEC Color monitor) Interleave Read Write Seek 1:1 44 458 31 1:2 77 455 31 1:3 109 116 31 1:4 142 146 31 Note that the drive came configured at 1:4 (the manual only mentions the MacPlus, so this is probably the best setup for this machine). I eventually decided on 1:3, though gave serious thoughts of having very fast reads for the slow writes. On real data 1:1 might actually be better. Does anyone have any comments on this? Finally, a comment on Mac software and the Mac 2 -- a lot of programs that I have tried would bomb. However, If I would go to the control panel and reconfigure to 'B&W' and '2 grey scale' (rather than color and 256) many of them started working. - mike newton@csvax.caltech.edu {ucbvax!cithep,amdahl}!cit-vax!newton Caltech 256-80 818-356-6771 (afternoons,nights) Pasadena CA 91125 Beach Bums Anonymous, Pasadena President Life's a beach.
