RiscPC in tower position
Roger Hird
I think that when I bought it in 1997, using the RiscPC in tower
mode, as I think of it - ie sitting on its side - was an option.
There may even have been special feet provided.
Sometime since, in an earlier search for more space, I was
advised by someone who seemed to be an expert not to try to
operate the RiscPC on its side, for resons I can't recall.
Is there actually any reason not to use a RiscPC on its side?

I have heard it said that once the HD bearings have bedded in in their
horizontal position, it is unwise to change.
With a new HD - no reason why not.

No, but you do need the feet (or a couple of strips of wood) to raise
the case from the supporting desk, otherwise the ventilation grill will
be blocked. You also need to check that the CD drive can retain a CD,
when operating on its side.

I think the possible problems of the bearings having bedded in, is
theoretical true and may in be true of some bearings, but I don't think
anyone has ever been able to confirm this has actually happened with a hard
drive bearing. I'm sure it has been suggested as the cause when some drives
fail after their orientation is changed but I don't know of anyone
dissassembling a drive and confirming this by inspecting the bearing.
Having said the case hasn't been proved, do you want to take the possible risk?
Only you can decide.

For years most if not all CD drives have been able to be run on their side,
they have four 'guides'. Some early drives had swivel guides but
manufacturers found a better way.

The reason why the feet were discouraged was that a Risc PC on
its side, on those feet, could not pass a topple test which
forms part of the mandatory safety requirements for that class
of equipment.

Many people already mentioned the harddisc.
I'd like to extend this to every part subject to wear and tear,
so include PSU fan and a possible CPU fan. FDD perhaps but
only if you used it a lot in the past.
FWIW: I got me a RPC when the 700 series just emerged and it
has been in tower mode since Day One and up to now never had
a problem caused by this set up.
The machine even used to stand on a carpeted floor for some
time until I actually read the label at the rear.
From the cooling p.o.v. I'd say it might be slightly better to use
tower mode because the hot* air can leave the machine directly
instead of travelling past the lid to an air vent.

* That is, if you consider hot to be over 30deg. C :-)
For a while an old HDU raised this considerably, so hot is
also subject to your h/w configuration.
