There are a
couple of XXDP images available on the web, so you could build
an XXDP test that will boot from the TU58 emulator, and test the RX02 that
way.
Just curious, are there any XXDP images of rx50 floppies?
I used E11 and simh to run the xxdp images I found somewhere on the net
(bitsavers?). Then I first made a virtual RX02 diskette and made it
bootable. Then I made a second virtual RX02 diskette with the programs I
wanted.
After having the images ready I transferred them to the original
diskette using vtserver.
The same way I made my RT11 floppies....
