RE: Looking for good read/write optical drive

I am also looking into optical 128MB drives. I can add some salesy
information to the discussion.

Pinnacle Micro, 800/553-7070 
model PMO-130
list $1995, dealers are offering for around $1500 
Claim 19ms access on what they call a 1/3 stroke test standard to the
optical industry - note this is NOT the same test hard drive manufactures
use. WIth the 4MB cache, read/write transfer rate is 1.4MB. With out the
cache, read/write averages 360K. The PMO-130 was released before the 11-92
MacWorld optical disk review. The PMO-650 which shares software and cache
technology was the recommended buy for 650MB drives.  
NOTE: the split optics and  mechanism of the PMO-650 are NOT used in the
PMO-130. This is from one of their sales persons, even when I called him
on the fact that the sales literature specifically says it has "split
optic design". Even so, the numbers given for the PMO-130 are exactly the
same as the PPMO-650.

MacDirect, 800/621-8461
sold directly, NuDesign MOST $1298, NuDesign Epson $1188
The MOST mechanism drive was in the MacWorld review, it was one of the two
recommended 128MB drives. The MOST is said to have 30ms average access
time, the Epson 38ms. The salesperson could not specify the test used for
either model. Transfer rate is 512KB/sec and 768KB/sec for MOST and Epson
respectively. The spindle speeds are 2400 and 3600 in the same order. Both
have 256KB cache.

MacProducts, 800/622-3475
Magic 128 Turbo
sold directly, $1199
The earlier model (Magic 128) was the other MacWorld recommended buy. The
new model is the same Epson 3600 rev/minute mechanism as the NuDesign 
Epson listed above. Again, salesperson had only an Epson data sheet 
and could tell me what kind of test were used to derive access and 
transfer rate specs.

Errata:
The MacProducts salesperson said the drive could NOT be a  start-up
device. PMO's guy said theirs could, I forgot to ask MacDirect.

The PMO-130 has been shipping for less then 2 weeks.

All said drives come with cable and cdev/init, disk ejection is via trash
can.

FWIW, I've also heard the DeskWriter C referred to as the

some salesperson messing up, but like I said, FWIW.

I'm also a Dos/Mac user and I can tell you that most of the time graphics
(i.e. Windows) are not run in SVGA resolution (1024 x 740) because the
icons look too small.  The advantage however of being able to run at
different resolutions is that one can increase the amount of information on
the screen, which is something that Mac users can't do (economically that
is). So if you want to be able to run in multiple resolutions buy a Sony
1304 multisync or something similar.  There's one caveat though, none of
the trinitron monitors out there can compete with Apple's  monitor. 
They're VERY good, but not quite as good. Go to a local dealer, check the
multisyncs available and if you can, put them side by side with an Apple
monitor and decide what's more suitable for you.

I have read numerous articles on the pros and cons of a Mac PB Newsgroup.
This debate has gone on for a long time.  I have consistently read the
Laptop Newsgroup and seen the overwhelming number of articles dealing with
PC notebooks.  And I have no problem with that.  But we deserve our own
home as well.  When I have posted questions about my PB 180 in that group,
or in the mac.hardware group as well it seems to get overshadowed by other
issues.  I think it is time to deal exclusively with the Powerbook audience.
Especially with the expansion of the Powerbook family.

In your own program you need to set the randSeed low memory global, or,
yes, you will constantly get the same sequence. *If* you are using the mac

I doubt much more than 100dpi would make a difference - provided
you can use as many colours as you need.

You need more resolution on printers than on screens because
printers usually can't vary the intensity of each dot. Instead,
they must simulate intensity variation by changing the size of
the dot or amount of white space between dots (half toning).
A screen on the other hand - unless it's pure monochrome - can
vary the intensity of each pixel. Colour is even worse because
most printers only support some small number of colours (4 to 8) and
not only must change in intensity be simulated by changing the
density of dots most colours are obtained by mixing dots of
different colours, with limits on how this can be done to avoid
unwanted patterns (moire patterns).

You also should consider Drive7 which is also a fast stable driver if
it meets your needs. Each drives has its weekness. HDT has difficulties
with some Seagate drives, Silverlining with processing bad sectors,
Ontrack with its sluggish interface, Drive7 with its missing
write verfication (HDT PE misses this too!!!)

In my experience, the Daystar works flawlessly.  I wouldn't hesitate getting
the Daystar because of any incompatibility problems.

That being said, you might evaluate the prices for the upgrade vs. accelerator
 and factor in your own plans for the future.  The Daystar unit is portable
and will work on any machine (provided you get the universal model), and
probably any that you might buy in the future.  And Daystar will swap you for
the proper adapter at no charge.  Further, you can always upgrade the Daystar
easily and incrementally, simply for the difference in list price (or less if
they're having a special).

The LCIII upgrade doesn't really offer such flexibility.  However, if you
don't plan to get out of the LC for some time, keep in mind that the LCIII
board will have a not only a faster processor but also a wider data bus--_and_
it's straight from the mother company.  But then, there's always the old Apple
"gotcha" involved.  As is happening more and more frequently, Apple is
releasing products with subtle but sometimes important flaws, almost as if
they never got a chance to finish things completely.  I don't know if the
LCIII will involve any such problems, but keep in mind that your LCII works
fine right now, and the Daystar is completely transparent to a good working
Apple system.  That may be a major factor.  Also, the Daystar is completely
removable and turns your system back into its old self if need be, and has a
30 day no questions asked money back guarantee.  Can the LCIII upgrade say
that?

The floptical is, unfortunately, a format that never caught on.  Looking
through the ads, I see that the only people making the drives are PLI and
Applied Engineering.  I can only find one or two sources for the diskettes.
I think that for the price, the floptical is a great bargain.  I considered
buying one recently, but was turned away when I saw the lack of popularity.
If you buy one now, stock up on disks and consider what you have to be all
the media you'll ever get.  I expect the format to die out completely in a
year or two.

Anyway, one can get a Syquest for ~$399 these days.  The price per megabyte
is a little more expensive than the floptical.
