Just wanted to pass this on to the list, as when I posted about it earlier
several folks replied that they had, or wanted an ESR meter for working on
their classic computers.
One of the more popular (and for good reason) ESR meters is the Dick Smith
one. I believe the Dick Smith one was an implementation of an original
design by Bob Parker.
While the Dick Smith one is a great meter, EVB electronics partnered up with
Bob Parker and came up with a new unit. This one has exactly the same specs
as the Dick Smith unit, but a few really nice improvements.
Much better display quality (bigger brighter numbers)
More of a professional, polished looking case and probes
Much better protection from charged caps
Automatic power off after 3 minutes of inactivity (instead of 2)
More to the point, the Dick Smith meter is 50-60 USD in kit form, and 75 to
110 USD assembled (seems to average about 97). But you need a calibrated DC
supply to calibrate the unit once built.
The EVB unit comes preassembled, calibrated, with leads, for $87 USD
including shipping. For roughly the same bucks as the Dick Smith one, you
get a slightly better unit (same design).
More to the point, two days after I got my EVB unit, I got an email from the
owner at EVB. He just wanted to make sure I got my unit, that it worked
correctly, and that I was satisfied. Turns out there was a minor problem
with my unit, and he took a genuine interest in the problem and made it
right (was just a mechanical adjustment to the bananna plug sockets).
Most impressive in this day & age, so I wanted to pass on my experience and
recommendation.

I'm pretty sure that the stripes are at 2.5 m.
I'm also pretty sure that the standard says you should have 5 meters
between transcievers.
But I have actually never really understood why. Maybe just to not damage
the cable to much with vampire taps? There cannot be an electrical or
signal reason for this, as far as I can tell.

Nothing terribly special, but this fellow contacted me this morning about
a lot of Atari 825 printers new-in-the-box that he came upon. He's posted
one on the Vintage Computer Marketplace:
http://marketplace.vintage.org/view.cfm?ad=456
For you Atari fans, this would be a good opportunity to get a brand new
825 printer at a not-bad price ($20).

Hi again guys :)
I've got myself a storageworks shelf (with floor-stand hardware and the
smoked doors :D ) that has 3 SBBs and a HSD05 DSSI<->SCSI unit. It's
hooked up to my 4000/200 with a KFQSA MSCP DSSI card, and i've set it up
so that I can SET HOST/DUP/UQSSP/DISK 0 into the HSD05 and run all the
setup utils and toys there.
However, I don't know how to partition these disks under NetBSD - i've had
a bit of a fiddle with disklabel but quite frankly I get a bit lost, and
most of the time disklabel locks up on me anyway - I suspect this is
because it cannot know the true geometry of the disk it is talking to, but
that's just a supposition...
The three disks I have appear to the VAX firmware as DIS610, DUA620 and
DUA630 - all appearing as RF72 disks, and the VAX is netbooting NetBSD
1.5.2.
Can anyone explain to me how I can get these babies formatted so I can
eventually install NetBSD on them?
TIA

Hi guys - as per title really. Does anyone have a copy of any
documentation pertaining to the KZQSA QBUS SCSI adaptor local? I've
followed a couple of trails and hit dead ends. I'm looking to do a bit of
dev with the card...
TIA

Does anyone know if it would be safe to put a dish of Vinegar inside
a computer? I've got a Sun Ultra 60 that smells. I've already
sprayed the foam and fans with Lysol, and I've taken bleach to the
foam as well, plus I'm getting ready to put the front (which is the
foam that smells the worst) through the dishwasher.
However, the inside of the computer smells some as well, and it's
been suggested that I stick an open dish of vinegar in/near the
computer, changing the vinegar a couple times a day for a couple
days. I'm slightly nervous about this as Vinegar is 5% acidic.
I'm just afraid to have the system in the house, and power it up
until I get the smell beat down thanks to my allergies.

I've got an Sun Ultra 10 with a nice Creator 3D card in it.
Yesterday I scored a Sun Ultra 60 with dual 300's :^) Is there any
reason I can't move the Creator 3D card from the U10 to the U60?
