Paul,
	I too am looking to buy a tape unit, for <$400, and for OS/2.
I've been gathering information for over a month.  I am find that there are
three types of tape units --
	floppy controlled (or seperate controller, same technology)
		- ~$200, +~$100 for a seperate controller
		- internal
		- slow, 1MByte/min
		- add ~$100 for external
		- some OS/2 support is available (Irwin, Colorado (coming))
		- no UNIX support, that I know of

	SCSI with SCSI controller
		- much too expensive > ~$800
		- OS/2 and UNIX support

	parrellel port (external by definition)
		- ~$400
		- Colorado Tracker and Irwin EZ-Port
		- no OS/2 support (yet ?)
		- no UNIX support.

I'm not too happy with any of these choices.  I'll probably go for the
the parrellel port interface.  If the prices are about the same, I'll
probably go for the Colorado over Irwin, only because of thier reputation
as being the "industry standard". 

If you know of anything else, please let me know.

Sounds like the controller is an RLL type, so it used 26 Sectors Per
Track instead of 17.

>What is the relative danger in using the

Very dangerous unless you do backups daily.  (Unless the drive *is* a
251R certified for RLL, in which case it's 4 heads and 26 spt.)  Lots   
of folk do run RLL on MFM-certified drives, but there is real danger
of losing data without warning.

Standard interleave for XT's is 6!  That usually reduces the drive
performance and you can do better.  If you can run Spinrite II on it,
you can optimize the interleave easily.  The better performance will be
at a lower interleave than 6, but 1 is unlikely.

>
>What is the actual drive geometry?  

ST 251, 251-1 820 cyl 6 hd 17 spt 821 rwc 821 wpc 
ST 251R       820 cyl 4 hd 26 spt 821 rwc 821 wpc

The 251 & 251R are 40 ms access, the 251-1 is 28 ms

All these drives are 40 meg types.

Looks like you should replace either the controller or the drive so they
match.  

Odd that we should encounter the same problem, I grabbed a controller
from the scrap box the other day and it also was an RLL.  But I noticed
that Disk Manager kept offering me drives with "R" following the number
and wised up.

Hope this helps.

Is the card fast?  Does it come with 24-bit color windows driver?  Also, anyone tried the winbench on it?  I want the score, to compare with the ATI ultra+.  Thanks.

 Also, the street price for the base HP4 in Los Angeles is hovering

The 486 can run many of the instructions in fewer clock cycles than the 386,
it has an on-chip cache, and it has several instructions that the 386 has.

You mention the difference between the 386/387 combo and a 486 SX.  The
difference is the coprocessor :)  The 486SX doesnt have a co-processor

I imagine that these errors are due to something I'm
doing (or not doing) but I have no idea as to what that
could be. So I am asking for help.

I have a Gateway 2000 386/33 that I have recently installed
the SpeedStar 24X. I have identified the following problems
(each of which occur in MS Windows):

1. I cannot get the 800x600x32k to work. Windows starts up
but the screen is scrambled. It appears that the timings are
off. I tried different timing settings, but the ones that
give me a clear picture at other resolutions and colors
do not work.

2. With 640x480x16mil I have encountered two problems. The
first has to do with Windows complaining about memory for
the icons. Some icons appear as a black box.

3. The other problem in 640x480x16mil is that is appears
to running in 640x480x16. I.e. I use a gif viewer and the
colors are dithered. The picture looks better in 640x480x32k
than it does in 640x480x16mil.

4. While working in 1024x768x256, I think is after switching
to a full screen DOS window, the text will be scrambled in
Windows. I.e. the title bar, menus, etc. will have little
dots surrounding the words, making it illegible.

5. In 640x480x16, in Windows, if I move the cursor to the
far right edge of the screen, I get a small amount of static
where the cursor is.


The problem may be related to CONFIG.SYS or AUTOEXEC.BAT.
I don't have a printout of the files, but working from
memory:

I removed 1 line from each file which was for the previous
video card, a Diamond SpeedStar.

The installation program added a line to my AUTOEXEC.BAT:
   c:\ss24x\win31drv
or something similiar.

No other changes to CONFIG.SYS.


Does anybody have an idea as to what is causing these problems?

Is the HP4 duplex?  Or do we have to pay more for a HP4D?  I would assume
that with 2 trays, it would do duplex (like the 2 trays in 2D).

Most UART detection programs seem to be fooled by Windows 3.1's
virtualization, but MSD tells the truth, as far as I've been able to
tell.  If it says you only have an 8250 then you only have an 8250.
That's why you get more COM ports..
 
Different programs will say you alternately have an 8250 or a 16450
because they look the same to the software - it can display either, so
