Hi tofro,
I’ll try the Minerva ROM, when I have it spare, in the JM QL where it does work which I assume will resolve the conundrum?
Thanks
Tony

Re: MicroP Controller with Minerva Issue
The only possibility I can think if is if your Minverva also has TK2, and the floppy interface is set for the ROM port address...
