The other way around is the new Intel Overdrive, which boosts performance

Re 386 vs 486 - in addition to the cache, the FPU, and some new
instructions, there are significant differences in the number of
cycles required to perform a given operation. This is an important
part of the performance adavantage.

Here are some data on clock cycles required for the MOV operation:

Note that 486 usually takes fewer cycles than the 386, especially on the

that the Cryrix 486 clone also has fewer cycles per instruction, on

Yes it is needed (low current).

I did this a few weeks ago--- its real simple
Go to Rat Shack a buy a 7905(i think that is the number

This is a voltage regulator
   a- hook one pin to ground 
   b- hook one pin to -12V
   c- the last pin is you new -5v

note the mounting tab is connected to one on the pins
and needs to be insulated from
the chasie ground 
see the package for details.-also it is a good idea
to use a 10uf cap on the -5v to keep things stable.

Becareful about the wattage --- most xt supplies are 100-150 watts
and most of the ATs are 200 watts.  i dont have a lot
of cards or disks so mine works fine.  
if you plan on using big disks you may be in trouble.

I'll never buy a Seagate product again. I bought a 600 MB, which
developed stiction within four months. I *then* discovered I had only
a 90 day warranty, and paid $710 to have it fixed! It was running a
mail machine 24 hrs a day at the time. When I got it back, I moved it
to a Mac that runs several hours a day, and it has been working okay
since then. I keep my fingers crossed!

Of course, this may be just an isolated incident, but I'm not going to
give them another chance. As I said, never again!

I've wondered the same.  Specificly, if it will allow use of 3rd

In the interest of being able to remotely control various 
devices by signals sent over a telephone line, which may 
be simultaneously being used for modem communications, one 
should check out a very robust and well characterized 
product made by Moose Products, Inc. of 1510 Tate Blvd. SE 
Hickory, NC 28603, tel 704 322-2333, the model MPI-800/280. 

This company (Moose Products really is the name) is a long 
time, major manufacturer of security alarm systems and 
components.  The MPI-800/280 is a component, I think the 
cost is about $75, that will respond to various touch tone 
sequences by closing or opening any of 6 isolated contact 
relays (spdt 10A contacts) with local led indication, tone 
response verification, and many, many other control options.  

In fact, the flexibility and security features are probably 
more than simple computer reset require, but maybe you could 
also start the morning coffee or something.  The unit will 
require 12 volts at 150 millamp, is very reliable, and has 
a telco approved interface.  It also allows connection of 
a microphone to listen in to the environment, and a host 
of other options.  

As system components, Moose Products are sold through local 
(usually whosale only) alarm supply distributors, see your 
yellow pages.  

I have used one for control of a remotely bootable computer 
system for years.  One might prevail on a distributor to 
give one a xerox copy of the 12 page installation manual 
for evaluation.  The /280 is a relay board that is piggy-
back on the MPI-800 logic and control board.  

Good luck.

Well I got a pointer to an answer about these new
Cyrix chips, the Cx486SLC and the Cx486DLC
(thanks Henrik Vallgren).

I've now read two magazine reviews about them.  One in
May's Byte, the other in the British Computer Shopper (Sept).

Basically it seems that these chips really do just slot
in place of existing 80386SX and 80386DX chips, and
they do offer 486(SX) instruction sets, small (1K) on
chip caches and a new, fast, 32 bit hardware multiply
instruction.

BUT:

It seems that the chief performance gain (over a 80386)
comes from the cache.  So, unless your motherboard has
been designed for these chips, there's not much of a gain
at all.  There is a software fix (for DOS) which causes
the cache to be flushed every time some external
device DMAs to the motherboard, but that reduces the
performance gain.

So, I guess I won't be buying one after all, guess I'll
have to save up for a 486 (or a Sparc, or a R4000 etc., etc...)

I used to have something like this a few years ago.  I had a xenix system
that needed to be rebooted occasionally.  I used an Apple ][ that monitored
whenever the phone would ring.  Certain ring patterns would convince the
apple that the xenix system needed rebooting.  The apple had a serial card
that was hooked up to the console port of the xenix system.  The apple
would then feed the information necessary to get the xenix system back up.
The last thing the apple would do is then return to the ring monitoring.

ugly but it worked.......

Subject: WANTED: Info on decoding POST Parity Error codes
Date: 17 Aug 92 17:46:31 GMT
Organization: AG Communication Systems, Phoenix, Arizona

I have an old IBM PC (pre-XT) that has 256K on the motherboard (4 banks of
nine 64Kx1 chips) and an add-on card with another 256K using the same chips. 
It finally developed its first hardware problem:  When I turn it on, the
Power-On Self Test shows some code numbers (something like 201 2403; I don't
remember the exact numbers) and then PARITY ERROR 1.  

I'm sure that the numbers are trying to point me to the bad memory chip, but I
haven't a clue as to how to decode them.  I'd like to avoid swapping chips,
one at a time, looking for the problem.  Anybody know how to read these? 
Thanks in advance for any assistance.

Try another vendor of ide controllers. The CCAT-100/200/400 series have worked
for me in all 386/486 installations which wouldn't work with DTK/SEAGATE/WD
controllers. Probably due to bus timing...
