RK05 head alignment -- how difficult?

Hey folks: As some of you know, I've recently restored a PDP-11/45, RK11-C drive controller, and an RK05 drive. I'm now at the point where I'm working to recover and archive the contents of the dozen or so RK05 packs that I got along with the drive and controller. I've been inspecting and

LTO is what I use for large archives. Tapes and drives are plentiful and cheap. LTO-1 is 100/200GB, LTO-2 is 200/400GB (native compressed). DLT is older and lower capacity but cheap, Super DLT is newer and higher capacity and expensive. I also play around with DDS 1-4, AIT 1 and 2, dabble

A couple of things to check: 1. Are you using a null modem cable? You need that. 2. Is the baud rate set correctly? 9600 is typical for DEC consoles. paul > On Jul 23, 2017, at 7:27 PM, Douglas Taylor via cctalk > wrote: > > All > > I have a DEC VT320 that

I am trying to repair my DECstation 220 after a battery leak, and making some reasonable progress. I have reached a component that is unknown to me, so I don't know how it is supposed to behave. It is connected to the inputs of a CMOS NAND gate, where I measure a steady voltage of 1.8V, but the
