The newer plastic package 486SX won't even have the numeric,
if it makes you feel better about it :)  

What are the other limitations?  I don't know of any... except
that Intel initially offered only slower speed parts, but that
has changed.

>into a 16 bit bus.  You're loosing processor power for no reason at all

No... this is a problem with terminology which Intel created
and then left up to the rest of the world to clear up.  SX
does not mean 16-bits... it means less.  In the case of the
386sx, it did mean 16-bits and slower (although faster
processors are on the way... especially like the Cyrix 486SLC
which is 32-bits of cached CPU on the inside and 16-bits
outside).  For the 486SX, it meant no numeric and for a while
slower speeds.  Now when the so-called (not by intel) 586sx
hits the market, I'm sure there will be new sorts of
confusion!

You can't be serious.  I hear this "scream" from just about every monitor and TV
I've even seen.  Most people I know think I'm just hearing things, but they 
usually shut up when I can tell them exactly when they turn on the TV(no sound)
or monitor while in the next room.  Going to TV showrooms can REALLY get 
annoying! Thankfully, most of them are noisy enough that they overpower the
high pitch "scream" from the TV's.  I never knew exactly what caused the sound,
but I always thought that the tv's/monitors emmited some sort of high frequency
sound above the threshold for average hearing(which would explain why many
people can't hear it).

They cost *a lot* more. I have seen prices for overdrive that are quite
a bit higher than that of a *motherboard* with the same speed.

If Overdrive were not so high in price, one could buy a CPUless 486sx
motherboard (several manufacturers actually do have motherboards that
can take one of 386DX, 486SX, 486DX, with a universal socket) and put in
it just the Overdrive.

As things currently are the best upgrade paths are:

1) get a DX2 from a chip merchant. Hard to find one.

2) get a whole new motherboard.

3) wait for Cyrix's 486 clone that is double clocked and has the same
   pins as a 386DX, and then buy that and a 386DX motherboard.

AOC monitors are pretty decent.  While not being of extreme quality they
do give you good performance when you consider their price.  This is
based on my experiences with their 14" SVGA monitor (can't remember the

I got six responses (thanks to all) for my request in getting a 
Quantum LPS105AT working with a Quantum 40AT drive.  
With some playing around with to 40AT, I got both of them to work
with an occasional problem when I do a hard reboot (with the reset swtich):
I get a drive controller error.  Even turning the power off & on doesn't
fix it - pulling out the disk interface card & putting it back in does
the trick.  I just avoid pressing the reset switch but would like to know
what to do to fix it. But enough of that; here are the goods...

To summarize the pin settings for the 105 are:

Well, it's not all that bad.  The software you are talking
about is a simple little program which initializes the Cyrix
cache controller.  If none of the "extra" signals are
available on the m'board (and there are some good reasons why
at least a couple of them would be jumpered away for the AMD,
Intel, or C&T 386 chips), AND if the 386 socket is feed the
HOLD signal (for DMA), then Cyrix has provided methods to
still use their chip (wish the heck Intel would be so
thoughful).

As for the performance loss due to the "BARB" cache flush
during DMA, it depends on whether you have hidden refresh and
whether you do a lots of DMA reads from a DMA device (floppy,
LAN adapter, SCSI adapter, video board, 3270 emulator, etc.)
in comparison to the number of writes (writes have to flush the
Cyrix cache regardless of the special signals).  For most
applications, the Cyrix does an amazing job... no wonder C&T
decided to bow out of the market.  I'm sure that if AMD had
invested in as much R&D as C&T they would be out, too.  Cyrix
is really hard to beat... I can't wait to see what they pull
out from their sleeve in response to the Intel P5!

I have a Seagate 1102A and a new Maxtor 7213A. I can not get them to work

put them together the maxtor is not recognized.

I have the Seagate as the master and the maxtor as the slave. In this setup
the seagate boots, but the maxtor is not recognized by the bios or an 
IDE infomation program.

I've tried having the maxtor as the master, but nothing was recognized
at all.

Are the maxtor and Segate IDE's compatable?

Before I bought my 486 with Stealth VRAM in June, I had played with
machines in local stores and they had either Trident 8900 cards or
ET4000 cards (the latter being the CompuAdd HiREZ card in their "Hot

They were awful!  I played with the Windows Write program from 3.1 and
typed a few lines of text.  The Trident and ET4000 cards seemed to
flicker and flash the current line every time I hit a character.  I
entered text in multiple fonts, multiple sizes and multiple styles.
It took forever to scroll around or even redraw windows when
uncovered.

Then I tried a Stealth and everything was instantenous.  Scrolling is
very, very fast, even with multi-font/size/style text, redraws were in
the blink of an eye, etc.  I've only played with a few major Windows
apps, but the only one that was slow on my Stealth was Finale, the
music composition program, but that thing would be slow on a 486/1000
with 4 Tb of RAM :-).

Yes, the lack of OS/2 drivers really sucks!  But the Stealth does come
with drivers for stuff besides Windows, including various CAD
programs, MS Word for DOS, Lotus 123 for DOS, and others.

I haven't seen the Speedstar 24 so I can't compare it with the
Stealth.

I am using just such a machine right now.  Providing that you have enough
ram (4MB is good) a 16MHz SX with Hercules mono runs Windows very well
indeed.

In my (limited) experience svga cards seem actually slower than Hercules.

Yes, Windows in 386 Enhanced mode is a dog on a 386DX/33 machine with 2MB
but very usable on an SX/16 with 4MB.

>3) Invest in coprocessors?

I haven't tried this but have heard that Windows doesn't take advantage of
a math coprocessor.  Of course, if your users are spreadsheeting by all
means get 387's.

In summary, I'm happy with a 4MB 386SX/16 with mono-graphics (Hercules) video.
It seems to repaint the screen and scroll as fast as an 8MB 386DX/33 with
an ET4000 based SVGA that I use at work.  The only real problem is that some
applications use colors that map to black on black in monochrome (this is
has so far only happened with shareware and freeware apps .)

     Thats why you save your money and buy an overdrive chip instead of the
487sx.  Should plug into the same socket on most so you not only get the full
486DX, you get it at double the speed.


	This is also what I have heard.  I have only a 386-40, but PC World
had a big comparison of different 486sx systems and found the 486sx 20/25s
with the overdrive chip to be a better value than a 485/50 system.
