Zip disks use both sides of the media, and are a new design.
You're probably thinking of the Syquest EZ Drive, the major competitor
to the Zip.  Syquest already made a 270 Mb 2-sided drive, and the EZ drive
was apparently just a cost-reduced design that uses only one side to get
135 Mb.  I say "was", because the EZ Drive is now gone, replaced by the
EZ Flyer that gets 230 Mb.  I have no knowledge of whether it is still
single-sided.

OK, you're probably right.  But the principle is still valid.  Consider
the 486 chip.  The originally marketed 486SX versions, which were really
the full 486 with the math coprocessor disabled.  Production flaws which
only effected the float processor still left a chip that could be sold
at a discount.  Users who didn't need floating-point got a cheaper
computer.  But, so did the rest of us, since Intel was able to sell the
flawed chips instead of having to write them off.

I have been very pleased with my Apelco Loran and VHF.  I don't need a 
small handheld such as Garmin 45.  Please let me know of your experience 
with this unit, good or bad.  Thanks Doug

I have a Garmin 45XL and I wish to use it for automatic navigation.
There are programs to download waypoints and routes and programs for
moving map display.
However, can the 45XL be told via the PC to use a certain route for
navigation and it will then report the off track error, etc.
It appears that for download the 45XL must be in Garmin/Garmin
communications and for navigation data it must be in NMEA/NMEA  mode. This
would require manual intervention at the GPS unit..
Basically, I want to use the Garmin GPS as the navigator and the PC as the
control. This way, no knowledge would be needed by the operator for the
GPS unit.
Has any one done this and how?
Thanks
Dan 

I have a Garmin 45 GPS unit for sale.  I'd like to get $225 US or best
offer.  No reasonable offer refused!  Please e-mail me at
liukb@kirk.northernc.on.ca for info or to make an offer.

Hi -
Unfortunately, the GPS2000 doesn't support DGPS corrections -- it only
has a external power adaptor, not NMEA. You'd have to get the GPS3000
or 4000 for DGPS.

Can one of the gurus teach us how Garmin's
Multitrac8 receivers differ from parallel
receivers and single-channel receivers? (please)
I'm asking because it seems to me that Lowrance's new
models with Rockwell parallel receivers should be better
suited for land-based applications than Garmin's multitrac8
which is NOT a true parallel receiver (as I understand).
However, the quadrifilar antenna of the new Garmin GPS II
might 'take up some of the slack'.  
Please educate us all.
Thanks

Hello. I've been looking around this and other satellite newsgroups and it 
sounds very exciting. Can someone PLEASE tell me what I need to "get started" 
in the hobbie of satellite's, satellite hacking etc., and how much it will 
cost. Im only 14, I dont have all the money in the world so I dont mind 
"cheap" or used stuff. I live in California, USA. PLEASE e-mail me if you have 
ANYTHING to say. Thanks!
