The Sinclair QL Forum

Thanks, that answers most of my questions. I believe they are Qlay based images. I'm still interested in if the magic number copy protection works as Xora added the ability to change the magic number when creating Qlay images.


Oh, you mean the media identifier? Hmmm, so it is used by programs ...

I see you have a 7400 piggy backed on top of the eeprom, on issue 5 PCB's you will find a socket or an empty space for an IC next to the jumpers, this is the space for the 74LS00.


Yeah, I found the socket and the resistors in the PCB after Jan's response, but the logic that implements that ...

I have a couple of questions, firstly does this use qlay *.mdv images or qemulator ones? or maybe both? and have you tested a copy protected mdv image yet?

To be honest, I have reverse-engineered the images from the ones that are in dilwyn's home page, so I'm not sure which ones are they, the ...

Great work

Thank you

Hi,

Nice wiki information.

I will see about getting PCBs made.

Would this work with an Oqtadrive setup as Microdrive?


It should, I have replicated the shifter logic for device selection and chaining so it should work with any other device in the chain, no matter if it is an oqtadrive or a ...

Ok, all is in place :)

I have created the [wiki](https://github.com/gusmanb/micropicodrive/wiki) at Github with instructions on how to assemble and use the device. Also I have added the BOM to the Hardware folder with links to the components, I have updated the mdv tools with the latest version and ...

Hi drgusman,

Welcome to the fold, your QL Microdrive to memory card replacement has generated a bit of a buzz. As do others a full documentation of your work will make interesting reading.

If you’re looking for another area to work on may I suggest removal of the TV coax and DIM Monitor socket ...

I have read that minerva does a special check on microdrives while formatting and if there aren't a bunch of damaged sectors it rejects the md, right now the firmware creates "perfect" microdrives so I need to verify that this is true and "kill" some sectors when a format is detected (it should ...
