Two points here: (1) I have the Phill's (Prime) boards for the Plus 3, if interested? (2) Please note: There's a BUG in the original Acorn ADFS 1V0 - it corrupts track 0 (zero)!! - To compensate for this, the Acorn (and others, if they're up to the mark) formatter writes a file to Track 0 and locks it - ZySysHelp IIRC. So, beware when using floppy discs formatted on other versions of ADFS - as they probably won't have the 'safety' file in place.

I'm not sure if the BUG affects the BeebSCSI (anyone know?) I've not seen it - but there again I've not been looking for it!!

Hmmm. This is missing from the hardware list. Will have to add that, guessing details are on the forum somewhere. Never ending task.

Edit: Tell a lie. I do have the Election Plus 3 Ram/ROM board

Not seen it myself as well. Likewise I've not been looking for it.

One thing I did notice with superform on the Elk that creating new LUNs results in a slightly different LUN size on the SD card from the quick start LUN.

E.g. Quick Start LUN: 524,140 KB, while creating LUNs with superform results in 524,172 KB.

Why go to all the trouble of creating LUNs - I just copy-and-past :mrgreen:

I do like experimenting with all the options. Sometimes it doesn’t work out so well. #-o
