Noel, About my earlier comments just making sure I understand precisely what you you're asking to price. I found the doc somewhere months ago sorry I can't remember where. I will upload to my site if I get a free moment and it's still on my computer. These are very heavy much more so than a cpu rack. Assuming you can wheel into a truck intact without disassembly and because it's a slave / pdp 11...$2000 if clean. Master unit double that price. I think that's the big differentiator because I am unsure what use a slave alone is worth without the controller set, but I am sure you have a plan/researched the solution B
