I had this problem on my NEC 3D.  I sent it back 3 times but the repair

The u82A had a graphics option, but you had to buy an EPROM and install it.
It's likely that yours does not have it installed.  Therefore all you can do is the
chunky graphics characters, not raster graphics.  Good luck finding an EPROM!

The problem is that those 4Mbits chips are not arranged like the
1Mbits: the matrix is bigger and hance there are more rows (as
DRAM is divided in rows and columns). That means that there are 
more rows to refresh. 
Refresh can be done in different ways, but one of them (not the best, 
but inherited from the past, when it was the only one) is to explicitely
specify which row to refresh (other ways just say 'refresh' and the chip 
decides itself which row to refresh).
Some chipsets are not prepared to deal with that many rows and hence
can't refresh some of them (they refresh 0,1,2,3,0,1,2.. instead of 
0,1,2,3,4,5,6,7,0,1,2,3).

That's the main problem with 3-chip Simms !

I'm about to buy 32 MB's of 4 MB x 9 sims.  My current hardware is
perfectly happy with 70 ns sims (386-40).  

But I'd like to plan for the furture.  Will motherboards in the future
see a big increase if I buy faster memory like 60 ns or 53ns.  The
price difference seems to be pretty small.

A friends 50 Mhz 486 uses the same wait states for both 70 ns and 60 ns.

Any input apprecitated.

	I had to answer this, since this is a growing section of Intel
machine land.
	System V Rev 4 is really a nice UNIX package. I personally purchased
Consensys SVR4 (I know, flame at me all you want, but I like it). SCO UNIX
is (last I heard) Rev 3.2, an older version, but with a lot of SCO's 
enhancements. SVR4 is a conglomeration of SUNOS (Including NFS, RFS, and it
even includes the daemon to run PC-NFS!!! At least Consensys has it!) and
AT&T System V. All in all, it all works pretty damn good! It blows away
MSDOS is a lot of areas.
	X windows works pretty good, but you need a LOT OF MEMORY. I have only
8Meg, and it has to swap a lot. You'd need more like 16Meg.
	As long as you have the sources to the X software you want to run,
and feel like recompiling it, you can run ALL X software on it. I have
not tried it, but will be shortly, but mounting remote disks on SUNs should
work. 
	Performance wise, a 80486 33Mhz is at least as fast as a Sun SPARC I
running SunOS 4.1.2. And a LOT faster in some things - up to 50% faster in
copying files from one place to another.
	All this, plus you get the economics of cheap parts! You don't need
to pay the premium prices SUN gets for it's stuff - as long as you don't mind
not being able to run all the elegant software that's available for SUNs.
	Check out the newsgroup comp.unix.sysv386 - it's devoted to only SVR4.

	What kind of extra cooling is required to run a 486SX-25 at
33MHz? I have one, and had planned to speed it up to 27MHz - I used to
run a 386-25 at this speed, with no problems, and no additional cooling
required. But 25 -> 33 is a huge jump. Should I install an IceCAP active
cooler? Or a heat sink? Or a heat sink plus a fan?

	Also, does anyone know of a good source of clock crystals by
mail or phone order? Normally I'd just drop into Fry's in Sunnyvale for
one but I'm ~400km from Silicon Valley right now, and not inclined to
make the drive for such a cheap component.

We had wierd memory problems with 486/50DX systems with 256K external cache
and 16MB.  The system would hang unaccountably while certain software was
running (the software was NOT exotic in any way).  We found the problems 
always went away when we ran in nonTurbo (10MHz) mode.

We had bought the systems locally from a dealer/OEM who diagnosed 
the problem as having to to with the external cache.  They checked with the 
motherboard manuf. and learned that the boards are made with 64K external 
cache and upgraded to 256K by hand.  The upgrade requires moving several 
jumpers on the motherboard.  On both of our systems only one set of jumpers
has been updated, enough to make the BIOS think there was 256K cache, but
not enough to let it work properly.

With all the jumpers now properly set, we are running with no problem.

	I was in Taipei last summer.  Judging from the size of the Taipei
world trade center, which was quite massive.  I would have to venture to 
guess that it would be about electronics in general.  But if you want PC
technology, I am sure there will be a plethora of PC related products at 
the trade show.

to walk for more than a couple of blocks and not tripe over one.  From my
experience last summer, there were as many PC stores in Taipei as there are
McDonalds in a major city in the U.S.

Has anyone seen any reviews on the Dell DE66/2?  Does it have
an external processor cache?  If it does, does it help performance?
How standard are the SIMMs and drive bays?  It seems they have
a very inexpensive box, with peripherals costing just a bit more
than bottom end prices.  If I can keep my peripherals when buying
a new basic box (perhaps a P6 system in two years... ACK) it would
make upgrading possible, as the perhipherals for a high end system
(16-32MB, x00MB disk, EISA SCSI, EISA video, etc...) cost more than
the motherboard, box and power supply assembly.

The unit is advertised with an ATI Graphics Ultra card.  Is ATI
going to have its EISA Graphics Ultra Pro card out soon?  Does
it support linear addressing of the video RAM?

Also, is there anything going on in the PC world with DSP cards
for audio work (like the NeXT DSP), or are the hotter sound cards
just synths with an ability to play digitized sound (ala Macintosh?)

Thanks, -Steve

Not that I'm a pro or anything, but for me (a non-degreed employee of Intel), 
one of the things I learned from the engineers is that current flow through 
the chip (and the heat given off) is proportional to the number of switches 
from 0 to 1 and vice-versa in a given amount of time.  With CMOS, the current 
flows during switching times, not at stable levels.  I would surmise from this 
that increasing the clock speed would cause a chip to heat up (why "pushed" 
chips fail). However, running it slower might not be good either, as there are 
probably dynamic nodes on the chip that lose the value (1 or 0) if it is not 
refreshed fast enough.

 That's not true. There are quite a bit of companies which offer

 486-33 LB.

 I don't know what's 'bare', but your price is about $1900 wich
 is not that bad. It's possible to buy fully equipped 486-50 in
 the US for about $2500.(I mean, 8 M RAM + 200 HD + LB accelerator
 and a monitor). SOmetimes cheaper. (the add I've seen showed $2395)

I am looking for a CD-ROM, which can work for both PC and MAC.
I like to know if SCSI is the must solution for that.
Can it play regular CD music? Can someone direct me the latest
article in Magazine about CD-ROM driver reviewing?
I don't read this group. Please send me e-mail if possible.
Thank you very much!

In the short-term, typing ^C at the dos prompt will cause most
versions of DOS to "throw away" the memory image of a disk's
directory.  It won't help you when using software that expects
you to change disks, though.

Your problem is with "changeline" support.  Sometimes it's the
drive, sometimes the controller, sometimes (rarely) a bug in
MS-DOS that only shows when particular versions of DOS run with
particular BIOS sets.
