People still forget, the PC in the bain house was around 10-15 years old at the time in 1994.
Phillips P3105. One that needed a boot disk and all I would suspect. Definately an old early 80's computer.

Anyway, the computer TURN ON time was a great focus at the trial.
But of course, thats not when the message is actually typed.
I know the issue is a red hearing, but if we could get some solid background on how long the computer takes to boot, then load up the word proccessor, that would be handy.
When you consider the computer being turned on, loading up, the Word programe being loaded, the user thinking of and typing the message, then assuming he did nothing else, moving on to kill himself, figuring out you cant do it the conventional way, contriving how to do it, geeing yourself up to, and then killing yourself, it doesnt look likely for Robin to have enough time before David gets home.
If the turning on of the computer, booting, loading up, and then typing of the message took 3 mintues (quite a minimal estimate), then a turn on time of any later than 6.41 is very unfavourable to David Bain. If David was at the gate at 6.45, hes in the house by 6.46 at the latest, and Robin cant have killed himself after he got home, he would have heard the shot or Robin falling and the gun hitting the ground.
So really, virtually all of the turn on times are very unfavourable to DB if he got home when he said he did. In reality he probably got home no later than 6.44 or 6.45.
The turn on time is about 5 seconds after you press the switch, after the clock engages. Factoring in the boot time, loading Word (already an old laggy computer), thinking of and settling on/typing the message, leaving the booth, going through the rigmorole of killing yourself (assuming you did nothing else), settling on the angle etc..
Basically, unless you go with the earlies possible time of a 6.39 turn on, theres not enough time for Robin to do everything before he kills himself.
The issues a red hearing to an extent in that Robin can still have switched on the PC and David be the murderer, however if you have the computer being turned on at any later than about 6.41, then by Davids story, Robin cant be the killer, as it's unlikely hes dead before David gets in the front door.
