Great system. I remember proxying a similar looking system. I can't remember the model off the top of my head, but it looked like yours but with dual 8" floppy disk drives and it weighed 125lbs. I paid UPS to pack it and they did a horrible job (they ignored my instructions on how to pack it and put a single layer of bubble wrap) and it got destroyed in shipping. Luckily it was mostly cosmetic (and fixable with glue), but a non essential card got broken.
Anyways back to your system, I hope you are able to locate a replacement CRT (if I recall, you told me the CRT was bad). Good luck with such a classic terminal.
