This could be because interrupts on a IIe (unenhanced only) wipe a certain page zero memory location. Anybody know why calls to the Applesoft Graphics routines don't like being called from an interrupt driver? I vaguely remember something about page 3 locations used by graphics routines. Anyway, if you have an unenhanced IIe, and you want to try clock Iclock, or Daemon, write protect your disks just in case. An errant interrupt driver is a difficult beast to kill -- Michael J Pender Jr Box 1942 c/o W.P.I. I wrote SHELL and Daemon, greyelf@wpi.bitnet 100 Institute Rd. send bug reports, suggestions, greyelf@wpi.wpi.com Worcester, Ma 01609 checks to me. People keep asking me if Shell or Daemon are compatible with the IIc, IIe. YES, I wrote them on my Laser 128. I mean, what would be the challenge to multitasking on a IIgs? I'll start writing dedicated gs programs when somebody sends me one in the mail.
