#486 BridgeBoards
17 messages in this thread
EMC is now shipping their 486SLC bridgeboards.
They are running at 33Mhz and come with 3MB of ram stock.
To all the people bound to see the ad for the 486SLC Gloden Gate board
avalible from Vortex. Please give us a call before you go out to get one.
We really BLOW vortex away with our speed and features.
Give the number below a call if you would like more information. We'll be
happy to Snail Mail, or fax our current brochure to you.

Dave: How about uploading a descriptive file to the library, detailing
specs?
Will do when I get a chance……It looks like there will be no more
changes to the board. Everyone who's been following this knows it jumpers
from 30Mhz to 36Mhz down to 33Mhz and has waffled between 2 and 3 megs on a
stock board….so I will wait just a little bit longer to make sure
everything is correct in the text file.

Dave,
I know that you've taken quite a few blows here lately, and might not
think of this but:
We welcome text files for our library that describe a new product. Why
not write up one and upload it, telling us all about the specifications
and abilities of your 486SLC BB? A formal product announcement is proper
for the message base so long as it does not solicit funds to be exchanged.
I the library, it is proper to give the suggested list price of the
product, and proper to give the address and phone number where people can
order or get more information -but it should be informational rather than
a wild sales pitch. I'm sure you know the difference.

Dave:
You seem to know a little (: about Bridgeboards – what do you
recomend as a 386 upgrade for the AT bridgeboard? Or, as I suspect,
do you recomend your 486slc bridgeboard? What kind of price difference
would there be between the two?
Thanks for any info.

Heres the great thing about us that you can't get with a Gloden Gate.
Upgradablity…. If you buy a C= 386 25Mhz now we will be able to upgrade
it to a 33Mhz 486 SLC in the future….and the best part is you lose
nothing in the upgrade, eveything is compatible (just make sure you put
60ns ram on it)
Current upgrade price is $675 an includes 2mb
Also if you already own a AT board we sell a 486SLC accelerator for that.
It is running at 24Mhz and includes a FPU, Price is $735. We recommend this
route only to people who have their boards running smoth and just need more
speed. The 386sx/486SLC is the route to go if you have nothing now.

Branden,
In addition to Dave's board (sorry, Dave!) there is the new Golden Gate
from Vortex, which is offering an trade-up for Bridgeboard owners (any
hardware emulator, actually). Ads will be appearing in December issues. I
haven't tested or reviewed it yet…next week is going to be busy.

We dump on the Vortex Golden Gate…………they are getting a Norton SI
rating of 45…we are getting 71!!!!
Dave
PS….remember Marion, I need this board back so no falling in love with
it. :>

Dave…
That's why I'm testing them—to find out who gets what rates.
Sorry I didn't call you back on Friday–I'll try Monday morning.

Is your 486 is the Cyrix 486SLC? If so is it the one with the 1K cache as
opposed to Intel's 4k cache? — Art
Yes….it is not possible to put an Intel(32-bit) chip in a 16-bit machine
though.
Don't let that fool you…..we are getting speeds just under a true 486-33
486SLC 33Mhz True 486 33 Landmark 2.0 105 115
Norton SI 66 69 (oops 71 was at 36MHz not 33MHz) MIPS

Dave: I was wondering if you read the article by Michael Slater in the
latest issue of Computer Shopper concerning benchmarks and in particular
the Cyrix 486SLC chip. And I quote "One of the most egregious cases of
benchmark abuse is now showing up in advertisements for systems using
Cyrix's 486SLC." And again, "On real programs, Cyrix claims only 1.4 to
1.6 times the performance of a 386SX". Don't get me wrong, I'm not here to
cause you problems but maybe you can shed some light on the 486SLC and
whether or not it really does offer a speed advantage. Seems like a 386DX
would be faster than the Cyrix chip.

Yes I read the entire thing….and it was the most unfair review i ever
read……be sides that….everything listed in thier is the 25Mhz…we are
running at 33Mhz.
My personal system is a 386 40 Mhz….and this flys past it

Well it does show that the Landmark & Norton SI Benchmarks should not be
used as a basis for comparing the performance of the Intel 486 and Cyrix's
486SLC chip. If the benchmark can fit in the 1K cache of the 486SLC, then
it is going to give some nice performance ratings. But in real world
applications, the SLC might not be as hot as everyone thinks it is.

John,
The problem is–how do you test something quantifiably in running real
world programs if you're not a programmer? You can't just give impressions
that "this was noticeably faster than that". Norton and Landmark give us
numbers we can compare.
I got some testing programs from PCMag, but they tend to measure disk
access. I'd like to find a TSR "stopwatch" for the PC side. Anyone know of
one? This stuff is a lot easier to do on an Amiga (thanks to multitasking).

Yes, but the Norton and Landmark series of benchmarks can be misleading in
that they check the raw processing power of the CPU itself, not the
complete computer system. Like it said in the article, the BAPCo suite of
IBM benchmarks might be a better alternative. It is an application based
series of benchmarks that test applications like Word Processors,
Spreadsheets, etc. Maybe that might be the better way to go to test new
hardware for Crossings.
