Re: [q] Quad 700 as firewall running Mac OS 8 or 7

2004-12-16 Thread Ken Watanabe
A Quadra can be used under Mac OS for that purpose, as a router and
firewall.  However, considering that there is a cost for buying the software
(like IPNetRouter) and the energy cost of keeping the Quadra turned on for
this purpose, and considering that a dedicated router/firewall device from
Linksys or Belkin costs about $50 these days (with very low power usage), it
does not make sense.  Those small devices are designed just for this
purpose, so they are very easy to set up and use.

If that Quadra was also serving some other purpose (such as a data server or
web server), then it might (?) make sense.

2124NB II Nubus Graphics Card (Micro Conversions)

2002-12-24 Thread Ken Watanabe
(this is going to both 1st-PowerMacs and Quadlist since it applies to both)

I picked up a still shrink-wrapped "2124NB II" Nubus Graphics Card (made by
the now-defunct Micro Conversions) on eBay for a reasonable price.  It has
some interesting features such as Zoom (zooms in/out on a portion of the
screen near the mouse cursor by hitting a hot key) and Pan (runs a bigger
"virtual desktop" and allows "panning" around it by moving the mouse to the
edge of the currently visible area).  It also goes up to 1152x870 resolution
at millions of colors and does some hardware-based QuickDraw acceleration.

A LowEndMac page says it is compatible through Mac OS 9.0.4 (not with 9.1),
but that's not entirely true.  The HARDWARE works in my Mac OS 9.1 PowerMac
8100 (with a NewerTech G3).  However, the SOFTWARE (a control panel) causes
screen "artifacts" in some situations.  Without the control panel installed,
the card seems to behave properly, but QuickDraw acceleration and the
Pan/Zoom features are not enabled (you still get millions of colors at up to
1152x870).  The card's performance is noticeably slower than the PDS AV Card
that is standard on "AV" Nubus PowerMacs, even with QuickDraw acceleration
enabled on the 2124NB card.

The performance difference is likely to be more noticeable in my case
because my 8100 has a G3; on a non-accelerated nubus PowerMac running Mac OS
8.6 or 8.1 (or lower), the 2124NB would probably work quite well.  I say
that because I put the card in a Mac OS 8.1 Quadra 700 (with a Daystar PPC
601).  In that system (using either the 68040 or PPC CPU), everything seems
to work perfectly and the performance of the card nicely matches the
performance of the Mac.

Now, my Quadra 700 (with max vram) already has pretty decent built-in
graphics, but I think I'll leave the 2124NB in it for now.  If I ever attach
a larger monitor to it, I'll be able to get 24-bit color at a higher
resolution and could even make it a "two-headed" system.

Happy Holidays!

Re: What is the smallest Mac ADB keyboard?

2002-03-20 Thread Ken Watanabe

A Google search on "small adb keyboard" revealed this link -

http://www.fentek-ind.com/minikb.htm

with a product called "Happy Hacking Multi Platform/Lite" (great name)
* Multi Platform - PC(PS/2), Sun/SPARC, MAC(ADB)
* Very Small Footprint - 11.6 inches X 4.3 inches
* UNIX/LINUX Friendly Layout
* 60 Full Size Keys
* Some Key Assignments can be changed by mode selector

Cool...  There used to be many specialized ADB keyboards.  I remember one
that looked like a standard keyboard, but everything was proportioned
smaller to about 3/4 size.  I think it was meant as a child's keyboard (or
for adults with small hands).

Also, not ADB (so sorry for being "off-topic"), but I saw this product
demo'ed at MacWorld SF 2002 and I tried it.  Thought it was unique and
clever...  and definitely small.
