In the sad and frustrating Corona times, however, there is time to expand some projects.
My RL01/RL02 emulator supports a combination of real and emulated RL disk drives but
always a DEC computer like a PDP-11 still is necessary to move data around. A new program,
called clonerl can directly read an RL01/RL02 disk and save it as a .DSK file used with
SIMH. Only(!) the 40pin flat-cable has to be plugged into the RL interface board by 180
degrees, i.e. reversed. However, there is one exception, the Power-OK signal which
requires a a small change ( DEC name was FCO ) on the interface board. This
project extension would also have to be tested with a real RL drive. However, this is
currently not possible for me due to lack of space and access to a working RL drive.
It has already been successfully tested with 2 DE10 nanobords + interfaces connected
together. I would be very grateful for a cooperation. As soon as it is confirmed
that it also works with a real RL Drive, the entire source code will also published
on GitHub. Details on my homepage http://www.pdp11gy.com/1AE.html
Please stay healthy and greetings, Reinhard
