Hi Peter, 

Yes, I remember passing some info on to you. Are you using it directly with
a SCSI drive or in conjunction with an Adaptec ACB4000/4070 adapter (or
similar) to an MFM drive?

I have a home made SASI/SCSI Host Adapter which I think I got the info from
Mark Usher some years ago and it is based on the Acorn Host Adapter, I have
used it on both my BBC computer and Master Computer with no problems. I use
it on the BBC with a E00 ADFS (Ver 1.31) to get around the memory problem,
it also works with the BBC 1.30 ADFS as I boot the HD with that and then
load in the E00 ADFS to claim the memory back !
I mainly use it on the BBC as all the games run better on that than on the
Master.
But it does work on both a BBC & Master with no problems.
