#5877 — Unipod query

Hi,

After the problems with my RiscPC, I'm building one back to how I had it
before. 
Is there any speed (or other) advantage to having the main Hard Disc 4
connected via my Unipod as opposed to the main mother board?
I looked in Archive for an article about the Unipod and any comparative data
but couldn't find one.
I posted on Archive-on-Line as well to see if anyone there has thoughts.

Regards,

Motherboard IDE i/face max about 1.8 MB/sec. Unipod 4 to 4.2 MB/sec.

Is it also not the case that (some) modern hard discs will not
run on the motherboard interface? David Holden could confirm.

I have been using 2 hard disc on one of the IDE ports of my
UNIpod for several years with no problems whatever.

Yes, possibly.

I had one on one port & the back-up caddy on the other. Worked perfectly here
too (until recently). I was just wondering what the advantage was. Now I know
from Dave Holden's posting what the actual speed improvement should be.

There's your problem. You've either got duff RAM, dirty contacts or C32
still present on a series 1 or 2 motherboard. You're wasting your time
faffing about with anything else until you sort this out.

That's what I suspected. 
What's the BEST way to clean contacts? A solvent, wire wool...????
Could a ribbon cable fault caused the RAM not to be accessed properly?
C32 ?? Could you enlighten the ignorant please?

Many thanks,

A contact cleaner you'll find in Maplin - or a decent car spares place. 
Don't use an abrasive as this could ruin the gold plated contacts.

Ta. I've got naptha & isopropynol. The reference to wire wool was, I admit, a
bit facetious.

I rather doubt that you have isopropynol.
;-)

There is only one way to put an -ol onto propyne, and I
imagine it would tautomerise to acrolein anyway.

And acrolein is one of the most unpleasant chemicals I have
ever had to handle.

Acrid, which is presumably the derivation of the name,
barely scatches the surface of how unpleasant it is...

And isopropanol isn't the proper name anyway (because there's no such 
chemical as isopropane). Propan-2-ol is the correct (though uneuphonious) 
name.

I'd guess it is IPA (Iso Propyl Alcohol)  - that was once a very common
contact cleaner.

I wonder how many people actually talk about propan-2-ol
rather than isopropanol or even isopropyl alcohol.

I would expect people to write propan-2-ol, as it is the
official name, and also takes up less space.

IUPAC names can be taken too far. Would anyone actually
refer to
(RS)-1-(benzo[d][1,3]dioxol-5-yl)-N-methylpropan-2-amine
rather than MDMA?

Oops! Sorry ! Must use my spell checker & try not to post quickly just before
dashing out to a gig in haste.

Just to clarify......

Propan-2-ol is also known as Isopropyl Alcohol (abbr. IPA - not the beer!), 
Isopropanol & 2-propanol.

Mine is manufactured by Servisol & is available from Maplins in a one litre
can labelled IPA isopropanol & a 400ml spray container labelled IPA 170
Isopropyl Alcohol. 

Naptha refers to a range of hydrocarbons distilled from pitch or petroleum.
Apparently even the Persians & Greeks could do that (Clever bods). The Naptha
I use is a very light, clear fraction of the distillate that's sold to clean
oil & grease from brake linings. It seems to be inert to most plastics &
paints which makes it good for de-greasing. 

Clear as mud then!!!

Think it's very similar to cigarette lighter 'petrol'. Which is handy to
have as a cleaning fluid, and easy to get.

I understand the Persians do nuclear too, though the Greeks can't afford
that at the moment.
