I'm on the verge of shedding a tear here. A friend brought in a 1084s monitor for me to test out the A4000T with and to my shock and awe, it works. The mouse seems to be dead, so I have to use the old A+ArrowKeys to get around, but it's enought to see everything in action!
Looks like I've got a 68040 (unknown clock speed as of yet), 2m chip + 16meg fast RAM, there are 4 hard discs, one inside the system, and 3 external (dataflyer shows 2x9.1gig and 1x2.1gig).
Here are some pics of it in action :
Workbench...

RAM...

Directory Opus...

Toaster Software...

I'm absolutely reeling from this.. time to head to my parent's attic and dig out my old 1084s and other hardware!
