PDP 8/e Help - File Transfer

Hi, all, I have a PDP-8E system with 24K (2x8K core, 8K DRAM), RK8E with two RK05's, RX01 8" floppy drive system, and a paper tape reader/punch (the reader needs work). I'm running OS/8 V3D. It was working perfectly for the longest time, then, very suddenly when accessing either RK05 drive, I get errors that are kind of strage. I don't get I/O errors, but errors appear to be corruption of data, e.g., a stuck bit or the like. Doing a DIR on a drive gives an invalid directory error rather than an I/O error. So, whatever is happening, the data seems to be coming off the drive OK (no CRC errors or other drive errors), but in the process of getting dumped into memory, it gets messed up. The machine boots up just fine off RX01 and runs beautifully, and completely reliably. Based on this, it appears that the problem is likely in the RK8E controller. On the RK05's, I've got KERMIT and ENCODE/DECODE, which made it easy to get programs off of a PC onto the 8/e. However, since I can't talk to the RK05's, I don't have access to these anymore. I don't have copies of these programs available on floppy. I need to somehow get the MAINDEC RK8E diagnostic loaded onto the machine to try to see what is going on with the disk controller. I need a simple way to transfer the binary image of the paper-tape version of the diagnostic from a DOS PC to the 8/e, without having to toggle in a big program. Any ideas?
