1. Right now I have a few color pictures created by various color demo
programs which I'd like to make into either startupscreens or
backdrops. Unfortunately, it appears that alot of the pictures
which I have require special programs to display them, and don't
support saving images as a PICT resource file. In particular,
I have images which are displayed by:
a. Giffer 0.96...I heard somewhere that there is a Giffer 1.0
which does support PICT resource files, but I haven't seen
it anywhere. It it exists, can someone mail me a copy of
it?
b. Image B3...apparently a program written at Apple for
showing off the Mac II when it was first announced.
c. Render Display...apparently displays data done by some
commercial package.
Any help in transfering these pictures from their internal formats
to standard color PICT resources types is appreciated.
2. This summer I was in Berkeley, and Mark Letzner (sp) of Apple, who
had a major role in the sound aspects of the Mac II came in and
gave a talk. One of the interesting points was that the Mac II
does a diagnostic when it boots up, and the chime heard upon
reboot/power-up indicates a sucessful diagnostic run. Apparently
different hardware problems detected during the diagnostic will
trigger different tones. Does anyone have a list of these tones
and the problems which they point out?
3. I've noticed that FKEY-3 and FKEY-4 don't like a Mac II in anything other
than 2-color mode. FKEY-4 just prints strange things on my
Imagewriter I, while FKEY-3 is a bit more intelligent about things
and just beeps. Wouldn't it be nice if FKEY-3 would dump the window
image into a color PICT resource file instead of a MacPaint file if
the screen depth is anything other than 1 bit? Has anyone written a
patch to do this?
4. I have a few 'snd ' beep sounds which play at the wrong speed. How do
I play around with the sampling rate to get them to playback at the
right speed. Also, Apple decided to make the Mac II beepsound
syncronous... which is a major pain since alot of applications
assume the standard beepsound (i.e., the beep on the Plus) and beep
a few times...thus a somewhat long beepsound really slows things
down (e.g., Smart Alarms triggering). Cheapbeep was kind of cute
in that it would retrigger a unfinished sound if another sound
follows it, kind of like when you hit the same key on a sampling
keyboard quickly when the sample is long. Has anyone patched
the sound routines to do something like this yet?
5. Is it safe to plug and unplug ADB devices when the machine is on?
