I have an ST251.  When the room temperature gets around 85 - 90 degrees F
(30 - 32 degrees C) the drive starts failing.  The problem is solved by
aiming an ordinary table-top fan at the back of the case.

Hello all.  I'm not a reader of this group but I need some information
about a Adaptec AHA-1520 SCSI host board that my father picked up recently.
The manual (leaflet) that comes with it is pretty limited, and it doesn't
give much indication of the board's features.  If anyone is familiar with
these boards, or can quote me some info from a magazine or whatever, I'd
appreciate it.  Please respond via email, as I don't have time to watch
the group at this moment and with Christmas break coming up, I might miss
it, etc.  Thanks in advance.

The previous poster wanted to get the high resolution modes under Windows.

Not a bad price,  considering it's a NEC,  which tend to be priced
higher than other clones.  I think the latest verison of the PowerMates
use local bus video,  but I don't think it's VESA VL-bus and it's not
accelerated.  That means you'll get good very basic Windows performance,
but it's not as fast as you'll want for serious graphics work in a year
or two.

As far as the monitor,  I can vouch for the 3FGx.  It's a very good 15"
monitor - small dot pitch - flat square CRT - good resolution up to
1024x768 @ 60hz.   There are a few better 15" monitors on the market
with features like digital mode memory,  AccuColor,  higher refresh
rates,  etc., but for the price,  the 3FGx is a very good choice. You
might want to consider also getting the optional screen filter from NEC,
as  there is a  tendency for that screen to reflect direct lighting in
the room.

If number crunching speed is paramount,  you should look at a 486DX2/66
instead of the 486/33.  In pure numeric applications,  the DX2/66 has a
50-70% speed advantage over the DX/33.  You can get a 486DX2/66 system
with the same amount of memory and size of hardisk of the NEC for about $3000
from many different vendors.  For about $500 more than you're planning
on spending,  you can get a system with a DX2/66 and an accelerated
graphics card.  That makes the system faster today,  and more expandable
tommorrow.

I have these.

For Sale (6) 1-MB 36-bit SIMMs.

These just came out of my Compaq Deskpro 486/M.  They are good for several
different types of Compaq computers, as well as any other place that you can
use a 32-bit SIMM.  I know that the new HP Laserjet III's use these SIMMs as
well.  They are also used in SUN's, Zenith PC's, and other advanced computers.
With the rising costs of RAM, these pices will be going up soon.


I am asking $33 each plus shipping.

Well now you are a lucky man. It all seems to depend on your system 
configuration both hardware and software. The 4 millisecond interrupt
shutoff can occur within Smartdrv, windows task switching or a variety 
of other places. If your machine is reasonably fast and has a large   
amount of memory ( eg > 8 Meg) then during the course of your file
transfer you may never see a 4 millisecond shutoff since smartdrv has
lots of memory to write to and Windows has lots of memory to swap to. 
In addition if your file transfers were fairly small ( < 1 Meg) then   
you may have been lucky enough to avoid the shutoff. But in general it
will happen sooner or later sure as taxes and death.

You forgot the one monitor which will blow away any of the one's listed in your survey of 15" monitors.  That is the NEC 4FG monitor.  INMO none of the other monitors you listed could come close to the NEC in both sharpness of picture and abilities to control the monitor (colors and screen positioning).

Just a few facts...
There are about 120M PCs out but only about 60M that are 386SX/16 on up.
There are about 9M Macs out but only about 8M SEs on up.

Currently Macs are selling at a ratio of 1:4 to PCs.
For low-end Macs, you no longer pay a premium.

NT benefits application developers primarily. It makes their
applications much more portable between architectures, greatly
increasing their potential market size, and lowering the cost of
development dramatically. It allows portable workstation applications 
to be delivered in a cost-effective, shrink-wrapped from.  

Users eventually benefit from lower development cost with lower
application prices, and NT runtime royalties  will probably be 
lower than comparable Unix royalties. Another user benefit is that it
provides a true common user interface for applications runnning on both
PCs and many different workstations. That lowers software training costs
considerably in a multi-platform environment. Users will also gain
access many DOS and Windows applications on their workstations. 

>Only if you think people are going to dump UNIX and flock to NT.  They

Current Unix users are not going to dump it for NT. To suggest otherwise
is ridiculous. But lots of Unix developers are going to develop for NT
as well as Unix. In the long run, NT may succeed simply because of lower
development costs  and, ultimately, lower application prices.

The first XT's has a XEBEC controller which had no ROM ... the HD support
