I'm confused. I didn't know that DEC made an RX51 drive and bitsavers doesn' mention it.
The RX50 is an unusual drive.
Assuming RX50: is the top slot in the drive and RX51: is the bottom slot, I have to ask, Are you flipping the floppy upside down when you insert it into the bottom slot? On real DEC branded diskettes there is a mark that lines up with an indicator on the drive that you can see when the door is opened. On the top slot it is on the right and the bottom slot it is on the left. If the floppy is not flipped over when in the bottom slot the drive will not see the index pulse. And if the drive doesn't see the index pulse it probably doesn't think there is a floppy inserted.
I apologize if you already knew this but I have seen this cause confusion.
it seems like the first gotek is somehow "intercepting" the calls to the second, but with them both on separate ports i'm not sure why that would be. maybe it is something in firmware that isn't accounting for RX50 behavior?
This is impressive and very encouraging. Sounds like you have a DECmate II working with a non-DEC display (in place of a VR201)? If so, could you post a pic and/or a wiring diagram of what parts are needed and how they're connected? Which OSSC module/kit do we need? Do you have it working with a VGA or HDMI display? What resolution? Thanks for sharing your expertise.i have the biggest smile on my face right now, that did it! i got a happy beep and a welcoming DECmate II screen this time, seems like she's good to go! ..
