The Software section contains wehat you need. The dump and restore utilities
contain programs for downloading files from PC to PDP 8/E, and you can
also use the send.c and rim.c programs if you want.

> 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.
