The 8086/8088 could be considered to be compatible with the 8080. Even though they could not run 8080 binaries, a dis-assembly/re-assembly pass could create a functioning executable.
To put it another way, the assembly language was backwards-compatible. You could not have done the same with, say, the 6800 or 6502, as which flags were set on add, flag types, etc. were not the same between those processor families.
You could take an 8080 binary, run it through a (fairly simple) translator, and be up and running.

Re:Why two ethernet controllers?

I can't think of any legitimate use for *two* ethernet controllers other than in a broader network application
I can think of two.
DSL modem (many of which use ethernet) and a regular LAN. I am told you can just put the modem on the LAN, but on my Linux gateway I could not make that work.
Thin client - very handy even at home, use your clunky old PC as an X-Terminal onto a server, 100BaseT private connection de-congests the (maybe 10BaseT) LAN
I gather the engines were not as good as the Concorde. Concorde had the Rolls Royce Olympus engines - superb, old design first used on the Lightning, and susequently on th Vulcan.
I heard that the Tupolev TU-144 needed afterburners to pass through the sound barrier, and possibly also to remain there.
It is quite difficult to design an engine that must have all air going through the engine at subsonic speeds, for the air surfaces like turbine blades to work, and yet
propel the plane at supersonic speeds. Think about it.
Visited Goonhilly some time ago. It has a number of dishes now - from the very old ones, the biggest, to the new ones. The old ones had to track small, weak satellites in low earth orbit,
and consequently had a large diameter and had to slew fast.
The newer ones are smaller, and often fixed, pointing to satellites in geo-stationary orbit.
There there are a pair of microwave dishes (in and out?) that look small, but carry all the terrestrial traffic to/from Goonhilly.
At the time (12 years ago ?) Goonhilly carried almost all Europes transatlantic traffic.
At Wizzy Digital Courier we are putting together a system that can deliver Internet content in third world countries.
Read the site for all the details, but in a nutshell it implements bandwidth by carrying data physically on a hard drive instead of passing it down a telephone line.
Using 802.11b wireless ethernet cards at either end, a vehicle that makes regular trips to rural areas - be it to deliver people, beer, or bread - can become a conduit for Email and web content.
It uses Linux, UUCP for the transport, and WWWoffle web proxy. The proxy allows requests made at a remote school to be passed back to a well-connected server, which scrapes pages, and passes the content back to back-fill the remote proxy.

That is what killed Wordstar

When Wordstar - the most popular CP/M word processor - upgraded to Wordstar 2000 (well before the millenium..) they changed everything.
Everybody knew ^S^D^E^X left/right/up/down and the ^K file commands. It flowed as naturally to the fingers as vi commands do today:-)
I cannot imagine what possessed them to change all the keybindings - but it killed the product stone dead.
You can read "Principles for Delegation and Administration of ccTLDs" on
ICANN's site.
A little further down we read:-
4.4 The delegee should recognise that ultimate public policy authority over the relevant ccTLD rests with the relevant
government or public authority.
4.5 The delegee should work cooperatively with the relevant government or public authority of the country or territory
for which the ccTLD has been established, within the framework and public policy objectives of such relevant
government or public authority.
It is questionable that Mike Lawrie is following those directives.
Use LDAP as a library card file? Perhaps you could, but that sounds like a classic database application to me.
Powerful search functions? Like SQL?
The Lightweight part of LDAP means that it is optimised for reading, and
does not expect to be written to very much. Databases, on the other hand, could be considered heavyweight because, with transactions, they can guarantee the accuracy of the data.
You cannot run an airline reservation system on LDAP. If I update LDAP information, the next few readers might get stale data.
LDAP is thus lighter on resources, and, IMHO, would be a better tool for a library index.
In case people don't read the article:-) remember they spammed Usenet.
Usenet occupied a much more central role in geek life back then, but Usenet is definitely an
Opt-in environment - you expect to find kooks on Usenet.
I think they even crossposted - meaning that a good newsreader would mark the message as already read in cross-posted groups.
But you could not crosspost to all groups - so one did read the same message too many times - hence all the vitriol.. They were the folks people loved to hate..
The redhat 7.0 installer (anaconda, python, etc)
would run in 16 Meg. From 7.1 on, it needs 32Meg just to install. Grrr.
The operating system itself - a mail and WWW server - runs happily in 16Meg - why can't the installer do the same ?
I am recycling old computers here, and am stuck at RH7.0 installer.
The Christian Science Monitor is a quite excellent paper.
It has one religious article, that you are free to ignore. THe rest of the reporting
is superb - they have their own reporters, so it is refreshingly free from Reuters / AP Newswire
rehashes. Often as not, I read the news months before the mainstream press finds it newsworthy. It is great for International issues.
I have been using Tomsrtbt for years now. It had some glitches when
the ext2 filesystem was extended, but these were fixed a while back. However, I use ext3 as my filesystem because I can still use Toms Root/Boot. There is a whole collection of 'extras' - mostly
kernel modules and so forth, that you can use to create a customised boot disk.
You can even rebuild it under itself - no other installation necessary.
And lets not forget BusyBox - which makes most of these distributions possible. Even Red Hat boot disks use
BusyBox these days.
The tsetse fly is a very important element in the preservation of wildlife in Africa
Two cases stand out:-
Kruger National Park only retained its biodiversity for as long as it did because of the Tsetse fly.
Hluhluwe-Umfolozi park in Zululand is all that is left after a widlife killing spree at the turn of the century
in a failed attempt to eradicate the fly.
Since the stats are gathered in one place, a hitcounter,
my lynx-browsing will never be tallied, as I do not download those little GIFs.
Even under Galeon I flag it to not download pictures from other sites - so I will not show up there either.
Because South African companies like those addresses - makes them 'international'
Because hotmail doesnt have a.za address
Because google.com returns search results from the world, and the world is a.com place
I know Alan Levin because his office is next door to me - he is usually right in his pronoucements.
The digital divide is very real in a country where my (internet) phone bill is the same as my rent.
> I recall a company creating a transputer
That was Inmos - a British Microelectronics company.
It was a regular CPU - not FPGAs. However, it did have a stack architecture.
It was a parallel processing machine - 32 bit, integer, floating point, and onboard microscheduler to allow fast (20usec) context switches.
To properly implement parallelism between processors, it is also
necessary to do parallel processing on a single CPU. This is because it is always more
important to keep other processors busy than to get on with your own jobs.
The Transputer had a CPU, onboard 4K RAM, and four high-speed communication links to its brethren, each with their own DMA engines.
You can find out more from RAM's transputer page. I have my own transputer stuff too.
The article also comments on the declining role of Usenet. I quote:-
"But the threat of a ban failed to ignite an outcry from its customers, a symptom of the dwindling use of Usenet. Once a venerable platform for online discussions, the influence of Usenet newsgroups has progressively declined, according to analysts and those in the industry".
I love/. - but its news has a half-life measured in hours, practically Chat. Usenet has a half-life measured in days, diligently archived by Deja News.
