I use the STM32_F4VE, and get it through AliExpress:

I'll be working with the RX driver for the standalone stuff soon on a project
of my own, I'll look into this then.
BTW, 'VTserver' refers to

16c550s are cheap as dirt. And you can stick a 16c850 or whatever the
latest incarnation is to a PLCC to DIP adapter.

Chuck really has the right answer here.

I thought about doing this with an FTDI FT245, which is a parallel to USB FIFO
device that looks like a USB serial port to the USB-side host. USB protocol
will manage all the “flow control” and so the PDP can write to it as fast as it
can.
We did a similar thing on Heathkit H89 and H8

Yep. I backed up the RD52 in a new-to-me MicroPDP-11 and it took hours.
> Be advised,
vtserver does indeed work for transferring RL02 contents to a binary image,
suitable for use with SIMH or E11 or whatever. Be advised, it takes a
*long* time, even on a 11/73 with the serial port turned up to 38400 bps.
Thanks,

You can simply boot with thr commanf
@ DL2
PDPGUI is a great tool to build actual disks from a simh rl02 image. This
way you can test first, get it working, then transfer via m7856 and m9312.
