I would add one additional thing. Static RAM is used for memory cache
because it is faster than dynamic RAM. To do any good cache memory
must be faster than the main memory. So cheap DRAMs are used for the
large main memory, and more expensive, but faster, SRAMs are used for
the cache.

Hello netters,

	I am interested in installing one of those fans that are
put over the cpu.  However, instead of buying one specially designed
for this purpose, I plan to just go down to the local Radio Shack and
pick up one of those small fans.  My question is, should the air be
blowing toward the chip or should it be positioned in such a way that
it is sucking air from the chip?  How are those after-market ones
setup?  Thanks for any info.

BTW:  it is preferable that answers be emailed to me directly, but not

Ditto here.  I bought a hard drive from them that arrived poorly packaged,
and vibrating as if it had been dropped from a plane (complete with bad
sectors in the boot area).
  
So I gave them the benefit of the doubt and arranged to send it back by
Federal Express.  They claimed the drive never arrived back to their
warehouse until 3 weeks later (something which Federal Express disagreed with,
complete with a signed, dated slip showing it had arrived there one day after I
sent it (by 2nd day air)).  Finally they sent a replacement (after much hemming
and hawing)... by slow UPS, even though I had requested 2nd day air.  The
replacement works fine, but it wasn't worth the hassle.

>Am I correct in thinking that local bus *does not* obsolete EISA?

Yes.

I haven't seen a board with all your specs, but V-COM (September
Computer Shopper pages 203-215) sells systems with a motherboard that
has both EISA(5) and local bus(2) slots and can take any Intel 486 currently
available.  Since the processor comes on its own expansion board, this
whole board could be replaced with a P5 board if they ever build one.
They have a 256k external processor cache that can be expanded to
512k.  Since the picture of the board shows only 8 SIMM sockets and
they claim to support 128 meg of ram on board, I would say this board
recognizes 16M SIMMS.
	The only place where this board fails to meet your specs is
that the local bus does not seem to follow the VESA standard, so
unless they have the only local bus cards you'll ever want (they do
have a 24-bit super-VGA local bus card) maybe you should wait for a
similar system with VESA standard local bus which will accept any of
the future local bus cards coming out.

O.K. Pay attention now :-),

1 Mb x 9 stands for 1 M*bit* x 9. Since 8 bits make 1 byte, 1 Mb x 8 becomes a
total of 1 MByte. The 9th bit is used as parity bit.

For 9-chip 1 Mb x 9 SIMMs it is easy: Every chip contains 1 Mbit of memory, so
the total is 1 MByte + parity.

The 3-chip 1 Mb x 9 SIMMs contain two 1 Mb x 4 chips, making a total of 1 MByte of
memory, and 1 parity chip.

In 1 Mb x 9, the 9 stands for "9 columns of memory" and *not* for "9 chips".

Hope this makes things a litle bit more clear!

That's the first I've heard of 1MB*3s.  What you're really referring to is
the fact that they use 1mb*4 bit chips instead of 1mb*1bit chips on the sim.

On an older 1mb * 9 sim, you would have nine discrete 1mb chips.

On a newer 1mb * 9 sim, you would have two 1mb*4 bit chips (= to 1mb * 8)
+ one 1 mb * 1 chip (sometimes they actually use a 1mb * 4 chip here too),
for a total of three chips.

It should make no difference whatsoever: both types of simms are 1MB * 9 bits,
just packaged differently.  The result should be transparent to the computer.

It works all right.  But you've got to be sure to change the interleave on the
XT hard drive or the data transfer rate will be crippled.  

For example, on an XT the optimum interleave is usually 3 or 4 (about
170K/sec).  But on an AT motherboard (with it's timing and bus clock
differences), the same interleave (with an XT controller) would result in 
a drop to about 25K/sec.  The optimum interleave for an XT controller in
an AT is usually 5 or 6 (which does give slower transfer rates (about
110K/sec), but considerably better than 25K/sec.

Often as not it's cheaper to buy a fast 1:1 AT controller to use with the XT
hard drive (mfm would get about 400K/sec avg througput, rll would get about
660K/sec avg throughput).  Of course, you'd have to reformat the drives
low-level...

Most AT 1:1 MFM & RLL controllers are now down to about $39 by mail order.

I have a problem that I hope can be solved by all you experts out there.
I purchased a Fujistu 520MB, 3.5" IDE disk and installed it in my 486-50
system.  It functions perfectly except that I hear a high-pitched sound coming
from the drive when it is spinning.  It sounds a lot like the noise some
monitors make when they are on but the system in off.  It's so high that
some people can't even hear it.  As you might imagine, it's quite annoying.
Anyway, I took the disk back and tried another Fujistu with similar results;
the noise was not as bad but was still there.  Then, I tried a Maxtor of
similar capacity and it made the noise too.  I then thought that maybe it was
the power supply making the noise, so I changed that and the noise remained.

I'm really at a loss to understand what's happening.  I find it hard to
believe that both Fujistu and Maxtor have this same problem but I don't
know what else to think.  It seems clear to me that the noise is coming from
the drive since it goes away when I unplug the disk's power cable.  Am I
the only person in the world that can hear this?  Have I been eating too much
cheese :-)?

Has anyone out there had a similar experience?  Please help!

	Only one model outthere which I haven't had a view of, that is the 6F 15"
(in Australia anyway). There aren't any 15" trinitron tubes to my brief, and I should 
think there isn't a trinitron Viewsonic model outthere. 
	Viewsonic NIs are quite nice things for making life. I'd had a 6L 3 months ago
which I sold recently just because I dislike egg-shaped(non-flat) screens. But if
you don't seem to disgust at non-flat CRTs, go for a 5e 14" which is a lot better
than the 6L since it supports faster 72mhz refresh rates. That sounds quite significant
to me. Or if you prefer a more comfortable and nice-looking flat screen, look at the
6F 15" which should be a newer model(claimed to support VESA's 72 mhz, too).

Well, they don't actually have a "BIOS".  And, remember: the IDE
controller is on the _disk_, not the adapter card! Tha card is just
there to help the drive cable and the PC bus to meet each other.  Also,
IDE controllers are usually interpreting, meaning that if you set drive
type 17, the drive will work with that size even though it's internal
layout was way different from the type 17 layout. Some drives require to
be set to drive type 47 (= user selectable values) to work, but most of
them will work with a similar sized setup option (to my knowledge.)

The 16C450 is a 16450 as far as you're concerned.  It's not going to
cause any problems under just DOS, but if you're trying to multitask
at high speeds under Windows, you may lose characters.

The C is CMOS.  82C50 is CMOS 8250, 80C186 is CMOS 80186.  It's low
power, usually used for laptops.
