Re: MicroP Controller with Minerva Issue

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

I remember that I once had a QL that if I plugged a MicroP floppy interface, and an Miracle expander RAM into. The QL would not work. Either card on its own, and everything was OK. I don't remember if Minerva was involved or not. I did not investigate it much, I think I just mixed and matched inter...

Which firmware has the MicroP controller, the original (with FDK device rather than FLP) or the replacement QJump?
It has QJump v1.19

Many thanks

Don’t think so

Can’t see any bent pins and all my other floppy controllers (various manufacturers) and other expansion boards are working fine in the Minerva QL

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... TK2 is disabled on the ROM, but it could be a QIMSI clash in that case. Will test Many thanks Still works in JM QL with QIMSI plugged in, so definitely seems to be Miner...
