[comp.protocols.appletalk] Timbuktu

Peter_Gaston@UM.CC.UMICH.EDU (12/19/87)

I just received a two-node copy of Timbuktu from WOS data
systems in Kansas.  It's a desk acc. which allows users
to remotely view and control other macintoshes over AppleTalk.
Initial viewing seems to indicate a very hot program.
We intend to use this system in a multiple Mac computer
meeting room.

(I have no connection with WOS data systems.)

This is not true. Timbuktu will operate on a machine that has no video
card whatsoever. I've been Timbuktu-ing headless II's, IIx's, and
IIcx's for quite some time now.

  I believe that the original poster explained that the a head-less IIci
using the built in video card won't allocate any screen memory for
the display.  I believe that Timbuktu requires this screen memory to
work, so I tend to agree with the original poster, and it is my
understanding that a head-less IIci can't run timbuktu, I welcome someone
correcting me if this wrong, since we are about to set just a system up
and weather or not we put a monitor on the IIci depends on this fact..

 Yes, I know it will work with a II, IIx, and IIcx without the video
 board.  This is because Timbuktu recognizes that there is no video
 board and allocates memory for the video image using it's SoftScreen
 routine.  The question had to do only with the IIci, since it functionally
 has a video board without RAM on the motherboard, and doesn't allocate
 the RAM for it unless it detects a physical monitor attached to the
 port.  Whether the SoftScreen routine works under these conditions
 is the question.

When timbuktu determines there is no video card, it goes into 
"SoftScreen" mode and reserves a portion of the II's memory as an 
"invisable" video monitor(the size of a Mac +'s video).  It is for 
this reason that it work's on headless Mac II family machines, I 
see *no reason* why the IIci would be any different...

  ahhh, but on the IIci there IS a video card, so will Timbuktu find this
card and not use the softscreen mode???

  Enquiring minds want/need to know, it's not that there isn't a video card,
it's that the video card won't allocate screen memory when it doesn't
find a monitor.
