...of articles like this... !FLAME ON!  An AT&T computer ? Which one ? Epson ?

The AT&T PC-6300 uses an 8 MHz 8086 uP. The Compaq Deskpro a 7.14 MHz 8086 uP.
I do not know what the Epson's uP is.

An 8086 running at 4.77 MHz (a Compaq Deskpro in slow mode) is 1.6 times the 
speed of an 8088 at 4.77 MHz (an IBM PC-XT). And even faster when compared at
an 8 MHz clock rate (8 MHz 8086 vs. 8 MHz 8088).


I also read an article in this group where someone wanted to upgrade an AT&T
PC-6300 with an accelerator card. Why? Most cards available have only 8 MHz
or 10 MHz 8086's, with some using 80826's at 8 MHz.

The gains made with the add-on cards are easily swampped by the software over-
head required to keep the I/O happy. A 4.77 MHz 8088 PC I might see, but....

KNOW WHAT MACHINE YOU HAVE BEFORE BUYING ANYTHING ! 

The guy with the 1.2 Meg floppy he's planning to put into a PC with standard
floppy controller... such a deal.

The misinformation to be had in this group is terrible. I wish only the known
facts could be posted, with all the drivel left out. net.micro.etc would then
be of real use.

Flame OFF.... OFF I said.... damn thing anyway....
