Wouahhh!! Ok I will try my best and first let me apologize, English is not my mother language.
Everything, really. If you don't mind sharing your experience.
For example,
It looks like a wall mount. Right there that is pretty unusual for 8x10.
It's made according to my specifications. My darkroom is quite small, no room for a standing version but you can get either one or the other.
How is that accomplished. Did it not come with a base?
It's fixed to the wall, base was already there and before that I had a Zone VI Type II 5x7" there, wall mounted too.
How big can you print with that?
at least 20x24" but I don't have easel or trays that size and I don't like too big prints. With a 8x10" negative if I print with a 240mm lens on 16x20" paper My head is about 50 or 60 cm from the top
How does the head move up and down? How does if focus?
Head and manual focus move with joysticks. It's autofocus or manual as you like or both. First you need to calibrate autofocus for each lens but it's very easy to do. You can store 20 calibrations.
What kind of negative carrier does it have? Glass? Does it slide in from the front or side?
Negative carrier has two glasses with one no newton rings on top.
Does it use Durst style lensbaords?
I don't know Durst style lens boards, it has heiland lensboards
Is the lens stage adjustable for alignment?
I don't know, it's already aligned.
