I have heard before from those who equate the entire Intel 808x family as a class.
From their perspective the Z-80 was designed around and
expanded upon the 8080 instruction set licenced
from Intel!
The deal gave 8080 programmers a second source, which raised the
credibility of the instruction set
against the Motorola 6800 family.
Motorola ended up cutting their own deal providing AMD trading some VMOS memory masks for
the 68xx
mask set, which they both second sourced for each other to a set of common customers who
demanded a
second source be available before they would finalize a design.
I agree Clone might not be the correct word choice, but by todays business standards is
not that far off the
mark.
As to the website in question, a quick look revealed it has not been updates in years, I
am personally
thankful that this person was just enough of a geek to have built a nice hobby page. but
how managed to
keep it unnoticed ?
This raises the question of "how much unnoticed?", I ran the page title and meta
content into YGAMS and
came up with some very interesting footprint info. (see
YGAMS.COM for the current beta and
examples of
the internet footprinting tool)
From page header
<title>My Virtual
PC Museum</title>
<meta content="John B. Sandlin" name="Author" />
<meta content="07/15/2002 PCs I've Owned"
name="Description" />
<meta content="John Sandlin" name="Keywords" />
"John B Sandlin" came up as a known with a YGAMS of ~253
The Title "My Virtual PC Museum" only hit ~ 2 on this side of never seen !
and "07/15/2002 PCs I've Owned" ~ 0 proves this has never been indexed.
It looks to me that these pages have been unseen and hiding for many years behind more
than just robots.txt
files. Believe me a YGAMS of 0 is almost impossible to maintain once something has been
published and
indexed gets indexed by someone!
There is little question this is fresh meat, none of the search engines have seen it YET,
but that could
change as soon as this mutterings got indexed, if I had but included a link to the page in
question.
BTW: Does anone here know who this is ?
Back to my rat-killen, I have wasted enough time today muttering :)

Just in its transmission, not including any possible problems someone might have with
