I bought an Acorn SCSI card for my R140 when they first came out and added
a Seagate St1096 as the boot device for RISCix. However my tests showed the
SCSI disc was exactly the same speed as the internal ST506 so I repartitioned
it without a swap partition and booted it from the internal disc again!

Does anyone out there know about the "new" version of RISCix (with MOTIF-X) for
the R140? Surely it must be ready for release by now? I phoned Granada about it
before Easter and they said it wasn't covered by my software maintenance and I
would have to buy it (even if I didn't want their external disc 'cos I've
already got one). Since then its gone very quiet.
