Attention NeXT Owners

I acquired some NeXT stuff. At this point it does not looking too promising mostly due to the monitors (all mono). The ones I have fired up are very dim and require a flashlight to be able to read the screen. Some questions for the list: I have adjusted the screen control on terminals like the VT320, so I was wondering is there a comparable control in the NeXT N4000 monitor? Depending on the monitor situation, I may have some spares with regards to keyboards, mice, cables, etc. I was wondering if the keyboards and mice are hot swappable. Can I boot a machine and test several keyboards or mice without a reboot for each? Next I would like to know if there are any current owners that are looking for a specific item to get their machine up and running. Granted we all know that there are plenty of list members wanting to acquire the first NeXT, But at this point I don't know if I am going to have even one good complete machine out of the mess. Therefore I would like to hear from those that just need an item or two. I am not offering at this time, just trying to get some direction as I tackle the job of discovering what I have and what works. If and when I figure that out, I will post what is available. Thanks, Mike Thompson
