Can do (unbound) book scanning - was Re: WTB: PDP-8/e handbook

I'm willing to scan any DEC books that are worn out and binding failing. I have a lot of handbooks etc that I won't cut and scan because they're still in good condition. But if somebody has falling-apart books, I can get them guillotined and scan them ADF. They can then be rebound - DIY or

I vaguely recall a T-1 network controller with a 8x300 series controller in an X.25 node about 30 years ago, but I don't have any supporting doco. I think it's pretty clear that uses other than disk controllers were very rare. KJ
