That is, until I helped install 40 new Mac Pluses in the computer center here this summer ("Kiewit Computation Center-- It's not just a job, it's a bomb shelter.") They were replacing 512KEs w/ 1 Meg Dove Boards, and most had been 128Ks to begin with. And yes, many had ghosts of the desktop. This seems to be due to students just ejecting their disks and walking away; we Student Assistants are vigilant, but we can't catch everything.So... save your screen! I have a question of my own: a friend claims the new Moire, which activates on shutdown now, does not park the heads on his hard drive on the shutdown. Does it allow the full shutdown procedure to take place? (Is there any way I can tell if my internal 80 Meg is getting parked?) And isn't After Dark's "Can of Worms" an attractive screen saver?

My old 512KE (with Dove upgrade) has a permanent menu bar now, with the Apple, File, and Edit menus clearly visible on the screen WHEN THE MACHINE IS OFF! It may take quite a few hours, but it definitely can and will happen! >I have a question of my own: a friend claims the new Moire, which activates >on shutdown now, does not park the heads on his hard drive on the shutdown. I've tried the new Moire (3.0), and quickly discovered that if it activates during a downloading session, the download stops. Moire 2.22 didn't do this; serial port communication always 'took precedence', and Moire would draw its patterns very slowly or not at all, rather than interrupt the current process. I didn't notice anything in the Moire 3 documentation that might account for this change (perhaps John can comment?) As for hard disk head-parking, it depends very much on the type of drive & driver software. Does the driver normally auto-park the heads, or is your friend using an INIT like SCSI Parker? >And isn't After Dark's "Can of Worms" an attractive screen saver?

[...] I too have had trouble with version 3.0 of Moire. It causes random crashes when the "Desktop/VE",the communications program I use. (Desktop/VE provides a Mac-style interface to Control Data mainframes.) 2.22 works fine. Dimmer here I come. --Pete Poorman pwp@shamash.cdc.com

Moire 2.22 didn't do this; It works all right for me (using VersaTerm, version 3 I think). Patterns get drawn very slowly, and the download seems to run at full speed....

You would have to look real hard to find an 80 meg disk that does not park the heads by itself when power is removed. Tim Smith
