If you can find a Computer Logics PCTD16 that should work in an old 16-bit ISA bus slot. I found a couple off of eBay a while back for under $20 each. Building interface cables might take a bit of work to split the 62-pin D-shell connector on the adapter to the (2x) 50-pin connectors on the driver. I have one PCTD16 connected to a Fujitsu M2444AC and one connected to a different flavor drive. I wrote some simple real mode DOS utilities to write TAP/TPC files to a tape and to read a tape to a TAP/TPC file. I used that to create a 2.11BSD setup tape from a PC. If your PDP-11 is a QBus PDP-11 there are multiple options. I've used Emulex TC02, TC03 and QT13 adapters and Dilog DQ132 and DQ142 adapters. Those are usually not too hard to find on eBay, but the examples currently listed seem overpriced. Making 50-pin cables for these with ribbon cable is easy if you have proper tools.
