We tried to run Timbuktu 3.0 on a "headless" IIci here at Farallon, and found that the machine will not boot without a monitor attached! Caveat: The IIci we have right now is not a real, production unit, but a "DVT 2" pre-release model, with beta ROMs. If we installed an external video card, or if we simply attached an un-powered monitor to the built-in video port, the machine would boot and Timbuktu will work fine. It seems that if certain pins on the video out port are jumpered, the IIci will be fooled into thinking that there is a monitor attached, and allocate screen memory, which Timbuktu can use for its SoftScreen operation. After the machine has booted up, you can remove the monitor and cable, and everything will work. We will know more about the situtaion when we get a real, production IIci in to test, and may be able to post a work-around here shortly.

Timbuktu does, in fact, work fine on a "headless" Mac IIci.
We just got a production MacIIci here at Farallon, and set it up
as an AppleShare server with no monitor or external video card
present. The machine would boot up and then we could control it
using Timbuktu 3.0f3 (the current shipping version). Apparently,
the many prototype units that were out there would NOT boot up if
no monitor was attached, and no external video card installed.
This problem was fixed in the final ROMs.
If you have a prototype unit, you can fool it into thinking it
does have a standard 480x640 monitor attached by jumpering pins 4
and 11 on the db15 video connector.
If you want to minimize the RAM that that the on-board video
takes, open the Monitors cdev and hold the option key down while
clicking on the "Options..." button. Choose "Black and White
Only". This will cause the machine to only reserve about 30k for
the built-in video instead of the usual 320k.
