Rephrasing, 
"I can use electronic mail and a VT100 terminal type. Can I use WWW? "

Answer 1 - electronic mail: 

The option to receive HTML files by electronic mail requires that you 
run a program which allows for 'local' loads of HTML files. This means 
that any file which is in html can be loaded from disk, and displayed 
nicely. This is a _formatting_ process. As soon as you access a link which 
is pointing to a http or any other resource which is unavailable to your 
station interpreting the file locally, you will fail. 

Consequence: 

Yes you can read HTML files if received from electronic mail. However, 
the 'surfing on the net' requires that you have interactive access to the 
internet with a 
<a href = http://info.cern.ch/hypertext/WWW/Clients> 
suitable client program </a> called 'WWW browser'.  

Answer 2 - VT100: 

Despite the fact that 'Mosaic' is much nicer to use and allows the 
display of in-line images and various goodies associated with graphics, 
the 
< a href=http://info.cern.ch/hypertext/WWW/Lynx/Status.html> LYNX </a>
browser allows you to utilize plain VT100 type of communications. The display 
of graphics *in-line* is not possible and you have to hope that people 
used something as a replacement (e.g., the 'ALT' directive like the 
following: 
<img src=http://www.ch.embnet.org/embnet.news/vol1_1/item.gif alt= +> 
This will have displayed the graphics 'gif' as in-lined image but on LYNX 
it will be visible only as '+' character. If it were 
<a href = http://www.ch.embnet.org/embnet.news/vol1_1/item.gif> an image </a> 
then this would be  a hypertext link to a external image, and, depending 
on how LYNX is configured, it can possibly handle this by archiving the 
file on disk 
and allowing a conversion into a printable format. 

Consequence: 

You can possibly run WWW in very convenient way on VT100 if you do not 
require clickable images (type ISMAP) or in-line images (those pages which 
come with graphics) that do not have a textual representation.
LYNX is used my many people out there and it runs on many platforms. 


: What software is there use html format pages?

If you run a WWW browser locally, there is the page at Cern which lists 
all possible clients, including those for Mac and PC. 
 
: Is there a better terminal type I can set my emulator to than vt-100?
:      (communication package is procomm plus v2.0 for windows)

There is no ultimate need to do so - VT100 is fine for LYNX, and Mosaic
is graphics-driven anyway.
